18a Female reproductive Flashcards
Diamond-shaped region between the pubic arch and coccyx
Bordered by the ischial tuberosities laterally
Perineum
Erectile tissue hooded by the prepuce
The exposed portion is called the glans
Clitoris (homologous to the penis)E
hair-free skin folds lying within the labia majora; homologous to the ventral penis
Labia minora
elongated, hair-covered, fatty skin folds homologous to the male scrotum
Labia majora
round, fatty area overlying the pubic symphysis
Mons pubis
Not present in all females
Source of Female ejaculation
Skene’s gland
Greater vestibular
Pea-size glands flanking the vagina
Homologous to the bulbourethral glands
Keep the vestibule moist and lubricated
(Bartholin’s) glands
Vagina
Wall consists of three coats
- Fibroelastic adventitia
- Smooth muscle muscularis
- Stratified squamous mucosa
Mucosa near the vaginal orifice forms an incomplete partition called the
hymen
upper end of the vagina surrounding the cervix
Vaginal fornix
Thin-walled tube lying between the bladder and the rectum, extending from the cervix to the exterior of the body
The urethra is embedded in the anterior wall
Provides a passageway for birth, menstrual flow, and is the organ of copulation
Vagina
Day 1 (Ovarian Cycle)
FSH released
The cycle starts anew
decline of the progesterone and estrogen results in sloughing of the endometrium and the beginning of menese
Days 26-28 (Ovarian Cycle)
maintains the thickness of the endometrium
Progesterone
transforms the ruptured follicle into a corpus luteum, which produces inhibin, progesterone, and estrogen
LH
Day 14
LH triggers Ovulation
matures the ovum
Estrogen
stimulates the egg to develop
FSH
mucosal lining of the uterine cavity (where implantation of fertilized egg takes place).
Has numerous uterine glands that change in length as the endometrial thickness changes- two layers: Stratum functionalis and Stratum basalis
Endometrium
Undergoes cyclic changes in response to ovarian hormones
Is shed during menstruation
Stratum functionalis
