External genitalia, Vulvamons pubis
labium majus
labium minus
clitoris
• The round ligament terminate at its anterior third;contain sebaceous glands,sweat glands and hair follicles
• Be richly supplied with venous plexus and vessels which may produce hematoma
• Contain numerous nerve endings
• Erection function
• Be richly supplied with nerves,which produce sexual excitement

vaginal vestibule
secretes mucus during sexual activity,becomes cysto or abscess when the duct is blocked
varying size and shape,the hymen is usually ruptured at the first sexual experience
congenital imperforate hymen
paraurethral gland,early be infected
• major vestibular gland
• hymen
• urethral orifice

position and shape
structure
• sex
• the way of menstruation
• soft birth canal
• canal,shorter anterior and longer posterior,enough distensibility
• fornix are formed at the top of vagina due to the projection of the uterine cervix,the posterior one is the deepest, and often be used as drainage point
• mucous coat muscular layer fibrous coat
mucosa: squamous epithelium, having no glands

promontory , divided the pelvis into
inlet true pelvis outlet cavity
• false pelvis (large pelvis) : assess the pelvis preliminarily
• true pelvis (small pelvis) : bony birth canal

types of pelvis
• gynecoid type transverse of inlet > anteroposterior intertuberal diameter > 10cm
• platypeloid type transverse < anteroposterior
• anthropoid type anteroposterior > transverse
• android type funnel-shaped , angle of public arch <
900

pelvic floor
contain multiple layers of muscle and fascia
3 layers :
perineum : soft tissue between vaginal orifice and anus
• superficial layer : superficial muscles and fascia
• middle layer : superior and inferior fascia and muscles between them
• inner layer : pelvic diaphragm , levator ani muscle

near organs
urethra : short but straight,about 4 ~ 5cm,easy be
infected
bladder : may prolepses in old female,easy be hurt during
operation
ureter : notice the relationship with uterine arteries
rectum : may prolepses in old female
appendix : distinguish with adnexal disease
