Reproductive test Flashcards
Penis
Male sex organ, transports sperm and excretes urine waste
foreskin/prepuce: double layer fold of skin protecting glans penis (head)
Scrotum
Sac-like structure that surrounds, protects and supports testicles
Testicles
two egg shaped glands that produce sperm
spermatic cord: contains vas deferens and all vessels and nerves for each testicle
Vas deferens
Continuation of the epididymis, joins the urethra
Prostate gland
Secretes fluid into semen to aid in sperm movement
Cowper’s gland
aka bulbourethral secretes pre-ejaculate fluid to wash out residual waste and lubricate urethra for sperm to pass, can contain sperm even if ejaculation doesn’t occur
Urethra
Passageway through penis to the outside of the body to release urine and reproductive fluids/materials
Spermatozoa
male gametes, aka sperm, fertilize ova
Ovaries
small almond shaped, located in lower abdomen on either side of uterus, produce ova
Fallopian tubes
extend from upper end of the uterus, carry ovum from ovary to uterus
Uterus
pear shaped, located btwn urinary bladder and rectum, 3 parts: fundus, corpus, cervix. 3 tissues: perimetrium, myometrium, endometrium
Vagina
muscular tube extending from cervix to outside body
Where are estrogen and progesterone produced
The ovaries
3 stages of menstruation
menarche: beginning of function, puberty, 28 days
perimenopause: transition phase btwn regular menstrual period and no periods at all, last 10 years, hormone changes
menopause: termination of function during middle age
What happens during postmenstrual phase of menstrual cycle
pituitary gland secretes follicle stimulating hormone, causing ovum to mature, ovaries secrete estrogen, stimulating uterus to prepare for zygote
Functions of placenta
temporary organ that allows for exchange of nutrients, oxygen, waste btwn mother/fetus, produces hormones necessary to maintain pregnancy
Functions of umbilical cord
carries blood, oxygen, nutrients from placenta to fetus, carries its waste to dispose, navel is formed from attachment
Gestation period
period of child development in utero, lasts about 280 days
Gynecologist
physician specializing in the diagnosis and treatment of the female reproductive system
Obstetrician
physician specializing in providing medical care to women during pregnancy, childbirth, and immediately afterward
Andropause
aka ADAM, androgen decline in the aging male, a progressive decrease of testosterone that usually begins in the late 40s
Cryptorchidism
A undescended testicle, a developmental defect in which 1 or both testicles fail to descend into the scrotum
Azoospermia
Absence of sperm in the semen
Oligospermia
Abnormally low sperm count of below 20 million/mL
Orchidectomy
Surgical removal of one or both testicles
PCOS
Polycystic ovary syndrome: condition caused by hormonal imbalance, ovaries are enlarged by presence of cysts that are formed by incompletely developed follicles
Orchiopexy
Repair of an undescended testicle
Oophoritis
Inflammation of an ovary, often occurs with pelvic inflammatory disease or salpingitis are present
Endometriosis
Condition in which endometrial tissue escapes the uterus and attaches to other structures in the pelvic cavity, leading cause of infertility
Menometrorrhagia
Excessive uterine bleeding at both the usual time of menstrual periods and other irregular intervals
Ectopic pregnancy
Potentially dangerous condition in which the fertilized egg implants and starts to develop outside the uterus
Preeclampsia
Pregnancy induced hypertension, edema and proteinuria
Eclampsia
More serious form of preeclampsia with convulsions and sometimes coma
Abruptio placentae
Disorder in which the placenta separates from the uterine wall before birth, leading cause of fetal death
Ovariorrhexis
Rupture of an ovary
Amniocentesis
Surgical puncture with a needle to obtain a sample of amniotic fluid used to evaluate fetal health and diagnose certain congenital disorders
Oophorectomy
Surgical removal of both ovaries
Hysterectomy
Surgical removal of uterus
Ovulation
takes about 5 days for ovum to pass through fallopian tube
Conception
fertilized egg is called a zygote, implantation to 8th week of pregnancy baby is called embryo
