Exam 4 Part 8 Flashcards
3 wall layers of uterus
endometrium
myometrium
perimetrium
endometrium
2 layers. if no pregnancy, inner layer shed as menstrual bleeding
if pregnancy, then contributes to placenta
myometrium
three layers of smooth muscles
perimetrium
outermost uterine layer, visceral peritoneum
vagina
birth canal -retroperitoneal
tubular organ, muscular
opens to outside via vaginal orifice
hymen
hymen
barrier across vaginal orifice “membrane”
vulva
external genitalia
includes cliorus
clitorus
homologous to penis in male, includes glans and prepuce
mammary glands
modified sweat glands; develop at puberty, secrete milk, both in female and male
perineum
diamond shape area between thighs; both in male and female
scrotum
posterior to penis; 2 chambers - 1 around each tesis
temp about 4oF below body temp; muscles raise/lower to adjust
testes
develop inside body, descent to scrotum before birth through inguinal canal
contain seminiferous tubules
lined with spermatogonia
spermatogensis occurs here
inguinal canal
where testes descend out of body before birth
seminiferous tubules
functional unit of male reproductive system
spermatogenesis
process by which stem cells become sperm
epididymis
where spermatozoa mature
coiled tube where sperm are stored and gain motility
connects to vas deferens
interstitial cells
among seminferous tubules, produce testosterone
vas deferens
part of spermatic cord
conveys sperm to ejaculatory duct (smooth muscle)
lops over ureter, widens forming ampulla where merges with duct from seminal vesicle to form ejaculatory duct
ejaculatory ducts
2 - convey sperm and secretions from seminal vesicles to urethra at prostate gland
prostate gland
1 - adds secretions to seminal fluid
bulbourethral glands
2 - distal to prostate, add secretions
seminal fluid
secretions from prostate, seminal vesicles, and bulbourethral glands: alkaline; nutrients; enzymes
semen
sperm and seminal fluid
urogenital opening
at tip of penis - where both urethra and ejaculatory ducts exit
