Document Summary
Female reproductive system ii uterus, vagina & perineum. Compare male and female reproductive & perineal structures. Cervix of uterus enters vagina at ~ 90 : forms deep recess fornix. Three layers: outer adventitia, middle muscularis, mucosa with transverse rugae. Relations: excretory duct for passage of menses, anterior: base of bladder & urethra, receives penis & ejaculate (sperm, lateral: levator ani, pelvic fascia, ureters, birth canal, posterior: anal canal, rectum, rectouterine, communicates superiorly with cervix pouch. Uterine artery branches off into vaginal artery to innervate the vagina. Forms floor of pelvis and supports pelvic organ; also forms roof of perineum. Urethrovaginal sphincter* - sphincter running around vagina; runs between external urethral sphincter & deep transverse muscle. Deep transverse perineal muscle: covered with perineal membrane. Pelvic diaphragm urogenital diaphragm superficial perineum. Erectile bodies (crus and bulb: females have bilateral bulbs around the vagina (males have a single midline structure, left and right crus come together to form the clitoris.
