Module 02: Care of Mother and Fetus During Intrapartal Period (Part 01) Flashcards
This is delineated to occur in non-reproductive cells and is known to generate exact copies of their parent cells.
Mitosis
How many chromosomes are entailed from an individual to generate an offspring?
23 chromosomes each
This is delineated to occur among specific reproductive cells or also known as gametes, hence they generate sperm and egg cells that are half of the genetic materials of their parent cells.
Meiosis
What makes mitosis different from meiosis?
(1) Four stages in total (plus the interphase)
(2) Happens in somatic cells
(3) Purpose is cellular proliferation
(4) Produces two diploid daughter cells
(5) Chromosome number remains the same the genetic variation doesn’t change
What makes meiosis different from mitosis?
(1) Eight stages in total (plus the interphase)
(2) Happens in germ cells
(3) Purpose is sexual reproduction
(4) Produces four diploid daughter cells
(5) Chromosome number is halved in each daughter cell and genetic variation is increased
What makes meiosis and mitosis the same?

(2) Vas Deferens
(3) Seminal Vesicles
(4) Ejaculatory Ducts
(5) Prostate Glands
(6) Bulbourethral glands
(7) Urethra
(8) Penis
What makes the male and female reproductive system comparable?
Although they differ greatly in both appearance and function, they are homologues, that is, they arise from the same or matched embryonic origin.
This is known as the study of male reproductive organs. This is constituted of the male reproductive system’s external and internal divisions.
Andrology
What constitutes that male external structures?
This includes the testes (which are encased in the scrotal sac) and the penis.
This is a rugated, skin-covered, muscular pouch suspended from the perineum. It functions are to support the testes and help regulate the temperature of the sperm.
Scrotum
What happens to the scrotal muscle when the weather is cold or hot?
(A) In cold weather, the scrotal muscle contracts and brings the testes closer to the body.
(B) In very hot weather, the scrotal muscle relaxes allowing the testes to fall away from the body.
Because of the scrotum’s function, the temperature of the testes can remain as even as possible to promote the production and viability of the sperm.
These are known as the two ovoid glands that are 2 to 3 cm wide, that rest in the scrotum. This is often characterized as the male reproductive organ.
Testes
The testes is encased by what?
A white fibrous capsule that is composed of a number of nodules, and each nodule is composed of Leydig cells or interstitial cells that produce testosterone and a seminiferous tubule that produces spermatozoa.
What do Leydig cells or interstitial cells within the testes produce?
Testosterone
What do seminiferous tubules produce within the testes?
Spermatozoa
When does the testes descend among male fetuses?
Testes in a fetus form in the pelvic cavity and then descend late in intrauterine life (about 34th to 38th week of pregnancy) into the scrotal sac. Because this descend occurs late in pregnancy, many male infants born preterm will have undescended testes.
(descent does not occur in the extrauterine life)
This condition is characterized when the testes remains in the pelvic cavity and because of this, it may not produce viable sperm and have a four to seven increase rate of testicular cancer.
Cryptorchidism
How do spermatozoa mature?
(A) The hypothalamus releases GnRH, which in turn influences the anterior pituitary gland to secrete FSH and LH.
(B) Androgen binding protein and testosterone then combine to form sperm formation.
(C) when the production of testosterone reaches peak amount, a feedback effect on the hypothalamus and APG is created, which slows down the production of FSH and LH, which then decreases and regulates sperm production.
This hormone in the male reproductive system is responsible for the release of testosterone from the testes.
Luteinizing Hormone
This hormone in the male reproductive system is responsible for the release of androgen binding protein (ABP).
Follicle Stimulating Hormone
Characterize the testes.
One testis is slightly larger than the other and is suspended slightly lower than the scrotum than the other (usually the left one). Because of this, testes tend to slide past each other more readily on sitting or muscular activity, and there is less possibility of trauma to them.
It normally feels firm, smooth and are egg shaped.
True or false. Spermatozoa can survive at a temperature as high as that of the internal body?
No, the temperature of the testes outside the body which is 1F lower than the internal body temperature, provides protection for sperm survival.
This is composed of three cylindrical masses of erectile tissue in the penis shaft. The urethra passes through these layers of tissue, allowing this male reproductive organ to serve as both the outlet for the urinary and reproductive tracts in men.
Penis
This is released with sexual excitement, from the endothelium of blood vessels.
Nitric Oxide (This causes dilation and increase in blood flow to the arteries of the penis (engorgement).
This is characterized as the muscle at the base of penis, which under stimulation of the parasympathetic nervous system, then contracts, thus trapping both venous and arterial blood in the three sections of erectile tissue.
ischiocavernosus
Characterize the mobility of sperm.
Sperm are immobile and incapable of fertilization as they pass through or are stored at the epididymis level. It takes at least 12 to 20 days for them to travel the length of the tube and a total of 65 to 75 days for them to reach full maturity.
The contraction of the ischiocavernosus muscle would lead to?
Distention and erection of the penis
This male reproductive part is characterized to be located at the distal end of the penis and is known as a bulging, sensitive ridge of tissue.
Glans
This male reproductive part is characterized as a retractable casing of skin that protects the nerve-sensitive glans at birth.
Prepuce
What are the recommendations of the American Academy of Pediatrics (AAP) on circumcision?
The AAP advises that circumcision decisions should be made in consultation with parents with consideration of their cultural or religious beliefs. Its advantages allow for lower rates of urinary tract infections, HIV, STIs, and penile cancer. Its disadvantages include surgical complications, such as bleeding and pain, and reduction of sensation with sexual stimulation.

(1) Epididymis
(2) Vas deferens
(3) Seminal vesicles
(4) Ejaculatory tracts
(5) Prostate glands
(6) Urethra

Oligospermia
This internal male organ is known as an additional hollow tube that is surrounded by arteries and veins and protected by a thick fibrous coating.
Vas Deferens (altogether these structures are referred to as the spermatic cord)
This internal organ carries the sperm from the epididymis through the inguinal canal through the abdominal cavity, where it ends at the seminal vesicles and the ejaculatory ducts below the bladder.
Spermatic cord
Describe the status of the sperm at the vas deferens.
Sperm complete maturation as they pass through the vas deferens. They are still not mobile at this point, however, probably because of the fairly acidic medium of semen
These are two convoluted pouches that lie along the lower portion of the bladder and empty into the urethra by ejaculatory ducts. These glands secrete a viscous alkaline liquid with a high sugar, protein, and prostaglandin content.
Seminal Vesicles
Describe the state of the sperm at the seminal vesicles.
Sperm become increasingly motile because this added fluid surrounds them with a more favorable pH environment.
This male internal organ is a chestnut size gland that lies below the bladder and allows the urethra to pass through the center of it. This secretes a thin, alkaline fluid, which, when added to the secretion from the seminal vesicles, further protects sperm by increasing the naturally low pH level of the urethra.
Prostate Gland
These glands lie beside the prostate gland and empty by short ducts into the urethra. They supply one more source of alkaline fluid to help ensure the safe passage of spermatozoa.
Bulbourethral Glands
Explain where semen is derived based on percentages.
(1) Prostate gland (60%),
(2) The seminal vesicles (30%),
(3) The epididymis (5%), and

(A) To produce mature and discharge ova
(B) Produce estrogen and progesterone
(C) Regulate the menstrual cycle
What happens if the ovaries are removed before puberty?
Absence of estrogen prevents maturation and maintenance of secondary sex characteristics and pubic hair distribution assumes a more male pattern.
How are the ovaries held in position?
By three strong ligaments that attach to the uterus and pelvic wall
Why are ovaries prone to silent tumor growth?
Because they are suspended in position and can enlarge significantly before causing symptoms of compression.
How many immature ova are present in each ovary at birth?
Approximately 2 million
What is the difference in chromosome numbers between reproductive cells and other body cells?

What are the three (3) layers of the uterus?
(A) Endometrium
(B) Myometrium
(C) Perimentrium
This layer of the uterus is characterized as the inner layer of mucous membrane. It supports pregnancy by thickening each month under hormone influence; if pregnancy does not occur, it is shed as menstrual flow.

The afferent nerves enter the spinal column at the T11 and T12 levels.
Why is it important to know that sensory innervation from the uterus registers lower in the spinal column than motor control?
It allows for pain relief during labor without stopping uterine contractions.
How does an anesthetic solution help manage pain during labor?
It can be injected at the T11 and T12 levels to stop the pain of uterine contractions without affecting motor control.
Which spinal levels are targeted for pain relief without affecting uterine contractions?
T11 and T12 levels.
How is the uterus supported within the pelvic cavity?
By ligaments, fascia, and muscle.
What happens if the ligaments supporting the uterus become overstretched during pregnancy?
They may not support the bladder well, leading to a cystocele or urinary infections.
This condition is characterized when the bladder herniates into the anterior wall of the vagina, potentially leading to frequent urinary infections.
Cystocele
This condition occurs when the rectum pouches into the vaginal wall, potentially causing constipation.
rectocele
What is the role of the posterior ligament in the uterus?
It forms the Douglas cul-de-sac, a pouch where fluid can collect, which is useful for diagnostic purposes.

Why is the vagina considered an internal reproductive organ?
Even though it opens to the outside, it is enclosed within the body.
How does the length of the vaginal walls differ when a woman lies on her back?
The anterior wall is about 6-7 cm long, while the posterior wall is about 8-9 cm long.
What are the vaginal fornices, and what is their function?
The fornices are recesses around the cervix that allow pooling of semen, aiding in sperm migration.
Why can an examiner palpate internal organs through the vaginal fornices?
Because the vaginal wall is thin at these points, allowing palpation of the bladder, ovaries, and rectum.
They make the vagina elastic and able to expand during childbirth.

This is characterized as the method of estimating ovulation time by changes in the mucus of the cervix that occurs during the menstrual cycle.
Billing Method
This hormone is known as the hormone of the mother during pregnancy. This promotes the development of the placenta and mammary glands. This is also responsible for basal temperature and mood swings of the woman.
Progesterone
What is the primary function of the progesterone?
This prepares the endometrium for implantation of fertilized ovum.
What are the secondary functions of the progesterone?
(A) Inhibits uterine contractility
(B) Inhibits production of Luteinizing Hormone (LH)
(C) Decreased GIT motility leading to constipation
This structure affecting the menstruation is known to release GnRH (Luteinizing Hormone-Releasing Hormone).
Hypothalamus
This hormone released by the pituitary gland is responsible for the maturation of the ovum.
FSH (Follicle Stimulating Hormone)
This hormone released by the pituitary gland is responsible for ovulation and growth of the uterine lining or endometrium.
LH- (Luteinizing Hormone)
This structure affecting menstruation contains the primordial cell activated by the FSH to begin to grown & mature.
Ovaries
This is known to cause the Graafian follicle to rupture and the ovum is set free from the surface of the ovary.
Luteinizing Hormone and prostaglandin
This structure affecting menstruation is known to be the organ of menstrual discharges.
Uterus
This is the time between the ending of the menses and ovulation. This occurs after menses. This is known as the rapid proliferation of the uterine mucosa.
Proliferative or follicular
What happens in the Proliferative or follicular phase of the menstrual cycle?
(A) With the activity of hormones, the endometrium begins to proliferate so rapidly the thickness of the endometrium increases as much as eightfold from day 5 to day 14
(B) On day 14, Estrogen is at its peak and will cause the rupture/release of egg from Graafian Follicle
This is known as the period after ovulation and before the next menses (10 to 14 days). This is known as the maturation and secretion by uterine glands.
Secretory or Luteal Phase
What happens during the Secretory or Luteal Phase?
(A) Existence of corpus luteum (formation of progesterone)
(B) Implantation of zygote will occur in this phase
This phase in the menstrual cycle occurs when the egg is not fertilized and the corpus luteum in the ovary regresses.
Ischemic phase
What happens in the ischemic phase?
(A) Production of progesterone decreases
(B) Endometrium of the uterus degenerates and sloughs off
This phase of the menstrual cycle is known as the menstrual flow and the end of the menstrual cycle.
Menses
What happens during the menses phase?
Composed of mixture of blood from ruptured capillaries, mucin, fragments from endometrial tissue and microscopic atrophied ovum
When does the fertilized egg mature from a single cell to a fully developed fetus?
38 weeks
Under the stages of fetal development, this is known as the first 2 weeks beginning with fertilization
Pre embryonic
Under the stages of fetal development, this occurs at 3 to 8 weeks or one to two months of pregnancy.
Embryonic
This pertains to the egg from ovulation to fertilization.
Ovum
This transpires from fertilization to implantation.
Zygote
This transpires from implantation to 5 to 8 weeks of pregnancy.
Embryo
This transpires from 5 to 8 weeks of pregnancy until the mother’s term.
Fetus
This pertains to the developing embryo and placental structures throughout pregnancy.
Conceptus
This pertains to the earliest age at which fetuses survive if they are born is generally accepted as 24 weeks or at the point a fetus weighs more than 500 to 600 grams.
Age of Viability
This phenomenon is also referred to as conception or impregnation. This is known as the union of an ovum and a spermatazoon.
Fertilization
Where does fertilization usually occur?
(A) Usually occurs in the ampullar portion (outer third of a fallopian tube)
(B) Must occur quickly because an ovum is capable of fertilization for only about 24-48 hrs, beyond this time, it atrophies
What are the three (3) separate factors wherein fertilization may depend on?
(A) Equal maturation of both sperm and ovum
(B) ATbility of the sperm to reach the ovum (motility)
(C) Ability of the sperm to penetrate the zona pellucida and cell membrane and achieve fertilization
This is released by the acrosomal head for sperm to penetrate.
Hyaluronidase
This condition is characterized to be the gestational tropoblastic disease wherein multiple sperm cells have entered the ovum that could lead to abnormal zygote formation.
H.mole or Hydatidiform Mole/Molar pregnancy
This is known as the fertilized ovum.
Zygote (travels from the ampulla to the uterus)
