Pelvis -Muscular Walls of the Pelvis Separated from Perineum by levator ani muscle/pelvic diaphragm Ala of the ilium is covered by iliacus muscle and psoas major Laterally it is covered by obturator internus muscle Posteriorly it is covered by piriformis Pelvic Floor is composed of the levator ani muscle and the coccygeus -Female Genital Organs -Internal Genital Organs Ovaries, Fallopian(uterine) tubes, uterus, and vagina **-External Genital Organs -Labia major, Labia Minor - Clitoris -2 Limbs Crura (covered by ischialcavernous) and body that ends at the glans clitoris -Function Erectile organ that is only used for sexual arousal - Vestibule Space between labia minora -Contents Opening of the urethra, vagina, and the greater and lesser vestibular glands Urethral orifice has paraurethral glands on the sides Vaginal orifice has a membranous gland that is called the hymen in virgins -Bulbs of the vestibule (corpus sponginosum of the vestibule) consists of venous plexus which is covered by bulbosponginosus muscles. It is consistant with the bulb of the penis -Injuries during childbirth **-Uterus -Parts Neck/Cervix, Body, and Fundus -Position, Mobility, and Fixation -Dynamic Support Pelvic diaphragm (levator ani and coccygeus) and other muscles -Passive/mechanical Support Bent forward over bladder (90degrees) to prevent from falling out -Pathology – loss of support Uterus may drop and may fall into vagina -Retroverted uterine Can cause abortion and dysparunia -fixation of the uterus Cervix is least mobile part -Blood Supply
