Q

Testes

A

paired oval glands
develop in abdominal cavity but descend into scrotum
covered by tunica albuginea
subdivided into lobules
each lobule divided into 1-3 seminiferous tubules

Q

Follicles

A

ovum + supporting cells

located in cortex of ovaries

17
Q

Uterus

A

womb
“metri”
“hyster-“

18
Q

Layers of uterus

A
  1. perimetrium - serosa; visceral peritoneum
  2. myometrium - smooth muscle
  3. endometrium - simple col. epi.; c.t.; inner layer shed each month, outer retained
19
Q

Vagina

A

birth canal
tubular, fibromuscular organ
mucosa lined with strat. squamous epi.
rugae allow for expansion and stimulation

20
Q

Clitoris

A

erectile tissue w/prepuce

21
Q

Labia majora vs minora

A

Majora - lateral fold, fat, hair

Minora - medial enclosed vestibule, no fat, no hair

22
Q

Alternate names for uterine tubes

A

Fallopian tubes

Oviducts

23
Q

Uterine tubes

A

not directly attached to ovary

infundibulum w/fimbriae surrounds ovary

24
Q

How does the uterine tubes transport ova to the uterus?

A
  1. Cilia lining the tubes - inward current

2. Smooth muscle - peristalsis

25
Q

How do the testes and ovaries compare?

A
  • Both covered in tunica albuginea
  • Both gonads
  • both paired
  • both produce gametes
  • both develop internally, retroperitoneal
