48
Q

the wall of the vagina consists of

A

3 layers

49
Q

inner epithelium of vagina forms

A

vaginal rugae that secrete mucus and other substances to produce an acidic environment

50

rugae produce

A

friction during intercourse to stimulate ejaculation

51
Q

middle layer of vagina

A

contains smooth muscle and skeletal muscle

52
Q

outer layer of vagina

A

anchors vagina in pelvic cavity and is made of connective tissue

53
Q

the vaginal orifice is partially to fully covered at birth by

A

a thin membranous hymen that usually ruptures during childhood activity

54
Q

the vagina serves as

A

the female copulatory organ, forms lower portion of the birth canal and provides a passage from menstrual flow out of the body

55
Q

the lack of testosterone during development causes

A

the mesonephros to degenerate

56
Q

while the absence of Muellerian inhibiting factor allows

A

the Muellerian ducts to differentiate

57
Q

Fallopian tubes form

A

upper, unfused, funnel shaped ends of Muellerian ducts

58
Q

uterus and broad ligaments form when

A

when middle portions of Muellerian ducts fuse

59
Q

inner two thirds of vagina forms when

A

distal portions of the Muellerian ducts unite with urogenital sinus

60
Q

what is homologous to the male vas deferens?

A

nothing

61
Q

the female external genitalia are collectively referred to as

A

A

fleshy folds covered by pubic hair that extend from the mons pubis

64
Q

labia minora
