2 layers. if no pregnancy, inner layer shed as menstrual bleeding
if pregnancy, then contributes to placenta

Question 3

myometrium

Answer 3

three layers of smooth muscles

Question 4

perimetrium

Answer 4

outermost uterine layer, visceral peritoneum

Question 5

vagina

Answer 5

birth canal -retroperitoneal
tubular organ, muscular
opens to outside via vaginal orifice
hymen

Question 6

hymen

Answer 6

barrier across vaginal orifice “membrane”

Question 7

vulva

Answer 7

external genitalia

includes cliorus

Question 8

clitorus

Answer 8

homologous to penis in male, includes glans and prepuce

Question 9

mammary glands

Answer 9

modified sweat glands; develop at puberty, secrete milk, both in female and male

Question 10

perineum

Answer 10

diamond shape area between thighs; both in male and female

Question 11

scrotum

Answer 11

posterior to penis; 2 chambers - 1 around each tesis

temp about 4oF below body temp; muscles raise/lower to adjust

Question 12

testes

Answer 12

develop inside body, descent to scrotum before birth through inguinal canal
contain seminiferous tubules
lined with spermatogonia
spermatogensis occurs here

Question 13

inguinal canal

Answer 13

where testes descend out of body before birth

Question 14

seminiferous tubules

Answer 14

functional unit of male reproductive system

Question 15

spermatogenesis

Answer 15

process by which stem cells become sperm

Question 16

epididymis

Answer 16

where spermatozoa mature
coiled tube where sperm are stored and gain motility
connects to vas deferens

Question 17

interstitial cells

Answer 17

among seminferous tubules, produce testosterone

Question 18

vas deferens

Answer 18

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

Question 19

ejaculatory ducts

Answer 19

2 - convey sperm and secretions from seminal vesicles to urethra at prostate gland

Question 20

prostate gland

Answer 20

1 - adds secretions to seminal fluid

Question 21

bulbourethral glands

Answer 21

2 - distal to prostate, add secretions

Question 22

seminal fluid

Answer 22

secretions from prostate, seminal vesicles, and bulbourethral glands: alkaline; nutrients; enzymes

Question 23

semen

Answer 23

sperm and seminal fluid

Question 24

urogenital opening

Answer 24

at tip of penis - where both urethra and ejaculatory ducts exit

Question 25

spermatic cord

Answer 25

testis to inguinal canal

includes: vas deferus, vein, artery, nerves, muscles, lymph vessels, CT

Question 26

penis

Answer 26

contains urethra; passageway for both urine and semen
distal end - glands penis; contains external urethral orific
prepuce (foreskin) -circular fold of skin at glands

Question 27

vasectomy

Answer 27

male sterilization
cut and remore portion of vasa deferentia proximal to most seminal fluid input
laparoscopic surgery
sperm still produced, reabsorbed by body
does not affect tesosterone levels
