Chapter 28 - The Reproduction System #2 Flashcards
The prostate is located? It surrounds”
Inferior to the urinary bladder and surrounds the prosthetic urethra.
This is a single donut shaped gland about the size of a golf ball.
Prostate
This gland secretes a milky, slightly acidic fluid that makes up about 25% of the volume of semen.
Prostate
Secretions of the prostate enter the prostatic urethra through?
Prostatic ducts
Name 2 unique substances that are found in the fluid secreted by the prostate gland.
Prostate-specific antigen & seminalplasmin
If this substance found in the fluid secreted by the prostate has increased levels in blood, it can indicate enlargement of the prostate, infection, or prostate cancer.
Prostate-specific antigen
This is an antibiotic that can destroy bacteria and is found in the substance secreted by the prostate.
Seminalplasmin
These are paired glands about the size of peas.
Bulbourethral (Cowper’s) glands
Bulbourethral glands are located inferiorly to? They are located on either side of?
The prostate / either side of the membranous urethra
During sexual intercourse, these glands secrete an alkaline fluid into the urethra that protects the passing sperm from acids in urine; they also secrete mucus for lubrication.
Bulbourethral glands
This is a mixture of sperm and seminal fluid
Semen
This is a liquid that consists of the secretions of the seminiferous tubules, seminal vesicles, prostate, and Bulbourethral glands.
Seminal fluid
Semen contains how much sperm per milliliter?
100 million
What is the pH of sperm?
Slightly alkaline (7.2-7.7)
This provides sperm with a transportation medium, nutrients, and protection from the hostile acidic environment of the male’s urethra and the female’s vagina.
Seminal fluid
This contains the male urethra and is a passageway for semen and urine
The penis
This is the opening of the tip of the penis that allows semen or urine to exit the body.
External urethral orifice
The tip of the penis aka
Glans
The body of the penis is composed of how many cylindrical, erectile masses of tissue that fill with blood upon sexual stimulation?
3
The masses of tissues located in the penis?
Corpus cavernosa & corpus spongiosum
These are the 2 dorsolateral masses of the penis.
Corpora cavernosa
This is the smaller, single midventral mass of the penis which contains the spongy urethra.
Corpus spongiosum
These are paired glands that produce female gametes and hormones.
Ovaries
The ovaries contain little compartments or bags that contain developing gametes in various stages. These are called?
Follicles
The ovaries are held in position by what 3 ligaments?
Broad, ovarian, suspensory ligaments
This ligament attaches the uterus to the pelvic cavity and also attaches to the ovaries.
Broad ligament
This ligament anchors the ovaries to the uterus
Ovarian ligaments
This ligament attaches the ovaries to the pelvic wall.
Suspensory ligament.
Females have two of these tubes?
Uterine (Fallopian)
Uterine tubes measure how long? They lie between?
4 inches / the folds if the broad ligament
This is the funnel-shaped end portion of each uterine tube; it is close to the ovary but actually opens to the pelvic cavity.
Infundibulum
These are the finger like projections of the infundibulum near the ovaries.
Fimbriae
These structures produce small movements that sweep an ovulated oocyte into a tube.
Uterine tubes
The uterine tubes eventually lead to and attach to?
The uterus
This part of each uterine tubes is a wide portion located medially to the infundibulum.
Ampulla
Fertilization usually occurs?
In the ampulla of the Fallopian tube
This part of the uterine the is the narrow portion that joins the uterus.
Isthmus
The epithelial lining of the Fallopian tubes contains what types of cells? These cells help move the female gamete (or fertilized ovum) toward the uterus.
Ciliated
What do the muscular walls of the Fallopian tubes do to assist in the movement of the female gamete toward the uterus?
The contract
A fertilized egg arrives at the uterus how many days after it is released from an ovary?
6-7
The main method of sterilization in females is?
Tubal ligation
In a tubal ligation, what is done?
The fallopian tubes are tied and closed then cut.
What is the result of tubal ligation?
The secondary oocyte cannot pass through the fallopian tubes and sperm cannot reach it.
This serves as the site of fetal development during pregnancy.
Uterus
The 3 parts of the uterus.
Fundus, body, cervix
This part of the uterus is the dome-shaped portion that is superior to the fallopian tubes.
Fundus
This is the central portion of the uterus.
Body
This is the inferior narrow portion of the uterus that produces mucus.
Cervix
The interior of the body of the uterus is called?
Uterine cavity
The interior of the cervix is the?
Cervical canal
This is the entrance to the cervical canal (from the uterine cavity).
Internal os
This is the entrance to the vagina (at the lower end of the cervix)
External os
Normally the body of the uterus projects anteriorly over the urinary bladder in a position called?
Anteflexion
A tilted uterus is flexed which way?
Posterior
These ligaments attach the uterus to the sides of the pelvic cavity.
Broad ligament
This ligaments lie on either side of the rectum and connect the uterus to the sacrum
Uterosacral ligaments
These ligaments attach the uterus to the vulva area
Runs ligaments
The 3 layers of tissue found in the uterus
Perimetrium, myometrium, endometrium
This layer of the uterus is the outer epithelial layer which becomes the broad ligament laterally.
Perimetrium
This is the middle layer of the uterus and consists of smooth muscle.
Myometrium
Labor during childbirth involves the contraction of what layer of the uterus?
Myometrium
This is the inner layer of the uterus. It is highly vascularized.
Endometrium
What layer of the uterus is sloughed off during menstruation?
Endometrium
