reproductive final Flashcards
female antrum?
nurtures and protects oocyte. contains growth factors, progesterone, hylauronic acid, estrogen. fluid secreted by granulosa cells.
mucosa of endometrium?
simple columnar with numerous tubular uterine glands in lamina propria
stratum functionale?
functional layer, thickest, sloughed off during menstruation
stratum basale?
source of regeneration for stratum functionale
straight arteries of endometrium
supply stratum basale
spiral arteries of endometrium
supply stratum functionale
function of female oviduct?
transport ovum from ovary to uterus
parts of female oviduct?
infundibulum, ampulla, isthmus, uterine part
infundibulum of oviduct?
funnel with fimbriae
ampulla of oviduct?
where fertilization occurs
isthumus of oviduct?
narrow part
uterine part of female oviduct?
opens to uterine cavity
mucosa of female oviduct?
simple columnar ciliated cells in mucosa and peg cells
peg cells function?
bathe sperm and ovum
zona pellucida?
ZP proteins help sperm bind, oocyte secretes proteins forming a coat with ZP proteins
female transition zone?
point where endo and ecto cervix meet with abrupt change of epithelium. CERVICAL CANCERS!
primordial follicle formation?
primary oocyte surrounded by flattened squamous follicular cells form ovarian follicle. dominant follicle depends on complex hormonal balances of FSH and estrogen, then primordial follicle becomes granulosa resulting in primary follicle
leydig cells
develop during puberty. secrete testosterone in testes
testosterone
steroid hormone that promotes sperm production and development of secondary male sex characteristics. production triggered by pituitary LH
what are the seminal vesicles?
exocrine glands consisting of highly folded, tortuous tubes.
what does seminal fluid contain?
fructose for metabolic substrate for sperm, prostoglandins to increase sperm motility in female reproductive tract, and fibrinogen to allow semen to coagulate
mucosa of seminal vesicles?
psuedostratified columnar epithelium
sertoli cells
large phagocytic columnar cells that are non dividing. form blood testis barrier, produces androgen binding protein, secrete fluid to carry sperm along tubules. exist in germinal epithelium of seminiferous vesicle
blood testis barrier
formed by sertoli cells. limits self androgen exposure to prevent autoimmune attack.
what does androgen binding protein do in sertoli cells?
concentrates testosterone
spermiogenesis
final physical differentiation process of spermatogenic cells in germinal epithelium. no cell division. spermatids condense.
what is formed when spermatids condense?
acrosome, midpiece, flagellum
acrosome
head, teardrop shape
midpiece
mitochondria
