Cards

Term
Corona radiata
Definition
follicular cells that accompany ovum during ovulation
Term
zona pellucida
Definition
adjacent to ovum. extracellular matrix proteins that form a barrier assuring species specific fertilization
Term
prostaglandins
Definition
stimulate muscle contractions
Term
acrosome
Definition
contains enzymes which are released when sperm reaches ovum
Term
acrosomal reaction
Definition
enzymes digest the outer membrane of the egg, allowing penetration of the sperm
Term
capacitation
Definition
maturation of sperm after ejaculation, making sperm "fertilization competent"
Term
zona reaction
Definition
makes the zona pellucida impermeable to other sperm; membrane hardens
Term
cleavage
Definition
mitotic divisions
Term
blastomeres
Definition
cells in the cleavage stage
Term
blastocyst
Definition
accumulation of fluid inside the blastomere
Term
trophoblast cells
Definition
hollow sphere of cells that will go on to contribute to fetal membrane systems
Term
inner cell mass
Definition
small cluster of cells; destined to become embryo and fetus
Term
ectoderm
Definition
gives rise to skin, sense organs, nervous system
Term
endoderm 
Definition
gives rise to digestive and respiratory tracts
Term
mesoderm
Definition
gives rise to everything else; muscles, bone, circulatory system etc.
Term
differentiation
Definition
the development of structural organization whereby cell types and structures differ from one another, rather than just a growing mass of homogenous protoplasm
Term
organizing effects
Definition
induce permanent sexual differentiation of various organs during early development
Term
activating effects
Definition
effects of hormones in mature organism
Term
interstitial cells of Leydig
Definition
TDF causes them to secrete testosterone
Term
vas deferens
Definition
a tube conducting sperm from the testis to the urethra
Term
seminal vesicles
Definition
lobe-type paired glands near the end of the vas deferens that contribute the gell-fraction to semen. This organ provides fructose, citric acid and proteins to nourish the sperm
Term
Congenital adrenal hyperplasia
Definition
adrenal glands produce not the normal adrenal hormone cortisol, but a substance that is structurally and functionally similar to testosterone
Term
seminiferous tubules

Definition
a smooth muscle that causes shrinking of the scrotum
Term
cremaster muscle
Definition
elevates the testes
Term
epididymis
Definition
highly folded duct approx. 6m long, for the passage of sperm from the testis to the vas deferens
Term
ejaculatory ducts
Definition
short tubes that descend through the prostate gland and terminate in the urethra; formed by the union of the vas deferens and seminal vesicle ducts
Term
prostate gland
Definition
surrounds the ejaculatory duct and part of the urethra; raises the pH of the vagina, provides lubrication
Term
cowper's glands
Definition
below prostate, 2 pea-sized glands; secrete thick clear mucus before ejaculation
Term
corpus spongiosum
Definition
houses the urethra, erectile tissue
Term
retrograde ejaculation
Definition
ejaculation "backward" into bladder
Term
broad ligament
Definition
suspends ovaries between the uterus and pelvic wall
Term
ovarian ligament
Definition
attaches ovaries to the uterus
Term
suspensory ligament
Definition
attaches ovaries to the pelvic wall
Term
round and uterosacral ligaments
Definition
suspend female reproductive system in the lower abdomen
Term
graafian follicle
Definition
mature oocyte; follicle cells have a fluid filled space between them
Term
infundibulum
Definition
funnel-like structure of the fallopian tube
Term
fundus
Definition
rounded region of the uterus, superior to entrance of fallopian tubes
Term
body of uterus
Definition
major hollow part of uterus
Term
cervix
Definition
connects the uterus to the vagina
Term
fornix
Definition
fold between cervix and vaginal wall - potential site for infection
Term
Greater vestibular glands (Bartholin's)
Definition
2 posterior glands, mucous secreting, can plug and make cysts
Term
lesser vestibular (skene's)
Definition
2 glands anterior to vaginal opening that produces mucus
Term
perinium
Definition
muscle and tissue located between the vaginal opening and the anal canal
Term
lactiferous ducts
Definition
get milk to the nipple
Term
alveolar glands
Definition
produce milk during lactation
Term
lutenizing hormone
Definition
signals ovulation
Term
progesterone
Definition
produced during the second half of the menstrual cycle; contributes to thickening of the endometrium which is shed during menstrual phase if fertilization does not take place
Term
