Anatomy Flashcards
Vulva
external genitalia of female, includes pubic hair, mons veneris, labia majora/minora, clitoris, urinary/vaginal openings
Mons veneris
“mound of venus”, area covering pubic bone, hundreds of nerve endings
Labia majora

Root
extends internally into pelvic activity, attached to pubic bone
Shaft
length of penis between glans and body
Glans
head of penis, richly endowed with nerve endings
Cavernous bodies (male)
structures in shaft that engorge with blood during sexual arousal

covering of skin over penile glans (male prepuce)
Corona
rim of penile glans
Frenulum
highly sensitive thin strip of skin, connects glans to shaft on underside of penis
Scrotum
scrotal sac, pouch of skin of external male genitals that enclose testes
