what is endometrium mucosa of the uterus
__ of oviduct has the greatest surface area ampulla
fetus implantation causes __ secretion cGH
LH functionhttp://www.studystack.com/Home.jsp?nointro ovulation, maintainence of corpus luteum
cGH function maintain corpus luteum
__ maintain corpus luteum cGH, LH
endometrium(mucosa) composition mucosal epithelium (simple columnar), lamina propria
__ layer lost after each menstrual cycle stratum functionalis
__ layer reatined after menstrual cycle stratum basalis
uterus histology endometrium (epithe, lam prop), myometrium , visceral peritoneum
beginning of uterine cycle destruction of stratum functionalis of the endometrium.
menstruation sloughing of stratum functionalis
when does menses occur when levels of progesterone and estrogen drop, causing sloughing of endometrium
proliferation phase also known as follicular phase
follicular phase also known as proliferation phase
secretory phase also known as luteal phase
__ causes menses constriction of the arteries in functional zone.
during proliferation phase, __ occurs rebuilding of the fuctional zone, and development of follicles
secretory phase between ovulation, degradation of corpus luteum,
during secretory phase __ occurs. ovulation, arteries invading functional zone
proliferation phase preceded by __ phase, followed by menses, secretory phase
which hormones play major roles in a)proliferation phase, b)secretory phase a)estrogen b)estrogen, progesteron
__ artery travel to basal layer of uterus straight artery
__ artery travel to function layer of uterus spiral artery
__ artery closed off due to contraction of smooth muscle during menses spiral artery
straight artery, spiral artery both present in endometrium of uterus
which female sex hormone loosens up connective tissue during end of pregnancy estrogen
vagina histology stratified squamous epith (non keratinized unlike skin), lamina propria, smooth muscle.
funtion of bacteria in vagina produce lactic acid which restricts the growth of pathogenic organism.
mammary gland is speciallized apocrinesweat gland
function of suspensory ligaments in breasts support mass of breast
majority of tissue in breasts adipose tissue
milk production stimulated by prolactin, estrogen progesteronn
milk ejection stimulated by oxytocin
oxytocin function contract smooth muscle in lactiferous ducts, sinus, ejecting milk
antrum found in secondary, tertiary follicles
In which stage of the menstrual cycle do ~20 oocytes begin to enlarge first stage ie. follicular phase
mucous secreting gland in female reprod system vestibular gland
__ becomes corona radiata cumulus oophrous
example of anastomoses in uterus ovarian artery/vein join with uterine artery/vein
scrotum analagous to labrum majora
testes analogous to ovary
bulbourethral gland analagous to vestibular gland
labrium major analagous to scrotum
ovary analagous to testes
vestibular gland analagous to blubourethral gland
__ encloses the testes scrotum
sperm also called spermatozoa
tunica vaginalis is serosa(peritoneum) which covers the outside of each testis and lines the scrotal cavity.
spermatic cord consists of Ductus Deferens, Deferential artery, Pampiniform Plexus, Testicular artery
inguinal canal links scrotal chambers with the peritoneal cavity
Raphe is a line between the two testes
dartos muscle contraction causes wrinkling of the scrotal surface
cremaster muscle contraction tenses the scrotum and pulls the testes closer to the body for heat conservation
which muscle causes wrinkling of the scrotal surface dartos muscle
which muscle when contracted causes testes to move closer to the core of the body cremaster muscle
a dense connective tissue surrounding testes tunica albuginea
tunica albuginea covered by tunica vaginalis
name membranes, muscles in order surrounding testes testes, tunica albuginea, scrotal cavity, tunica vaginalis, cremaster muscle, scrotum(dartos muscle, skin).
tunica vaginalis covers tunica albuginea of testes
between ___ and ___ there is a space called scrotal cavity tunica vaginalis and tunica albuginea
sperm production occurs in seminiferous tubuleq
rete testis is where seminiferous tubules interconnect to form a maze of passaways.
efferent ductules connect the rete testis to the epididymis
maturation of sperm occurs in epididymis
how many tubes make up an epididymis 1
stem cells of sperms called spermatogonia
when does mitosis of spermatogonia start puberty
spermatogonia becomes _ after mitosis primary spermatocyte
primary spermatocyte undergoes ___ and becomes __ meiosis1, pair of secondary spermatocyte
secondary spermatocyte undergoes __ and becomes __ meiosis 2pair of spermatid
a primary spermatocyte produces __ spermatid 4
1 speratid matures into ___ 1 spermatozoon
spermatogenesis begins at outer/lumen and moves to outer/lumen outer , lumen
Sertoli cells function blood-testis barrier, support of spermatogenesis, provide nutrient to spermatid
final stage of spermatogensesis known as __ and during this stage __ occur spermiogenesis, transform round spermatid to spermatozoan
how does spermatid get transformed into spermatozoan condensation of nucleus, formation of acrosome, development of flagellum
spermatozoon has mitochondria at midpiece
acrosome function breaks down zona pellucida
what breaks down zona pellucida acrosome
midpiece of sperm contains mitochondria
at birth testes contains spermatogonia, sertoli cell
importance of blood-testis barrier developing spermatozoa contain antigen not present in somatic cells. hence they would get attacked by the immune system had they been not protected within the tight junction between sertoli cells.
