female anatomy
The vagina is a thin walled-tube, 8 to 10 cm long. It lies between thebladder & the rectum & extends from the cervix to the body exterior. Theurethra is embedded in its anterior wall. Often called the birth canal, thevagina provides a passageway for delivery of an infant & for menstrualflow. Since it receives the penis (& semen) during sexual intercourse, it isThe highly distensible wall of the vagina wall consists of three coats:A mucosa marked by transverse ridges or rugae, which stimulate theThe epithelium of the mucosa is a stratified squamous epithelium adaptedto stand up to friction. Certain of the mucosal cells act asantigen-presenting cells & are thought the route of HIV transmission froman infected male to the female during intercourse. The vaginal mucosahas no glands; it is lubricated by the cervical mucous glands. Its epithelialcells release large amounts of glycogen, which is anaerobically metabolizedto lactic acid by resident bacteria. Consequently, the pH of a woman’svagina is normally quite acidic. This acidity helps keep the v
These glands release mucus into the vestibule & helpto keep it moist & lubricated, facilitating intercourse. The clitoris isrichly innervated with sensory nerve endings sensitive to touch, & itbecomes swollen with blood & erect during tactile stimulation, contributingto a female’s sexual arousal. Sperm freshly deposited in the vagina areincapable of penetrating a oocyte. Each mammarygland is contained within a rounded skin-covered breast anterior to thepectoral muscles of the thorax. Structures associated with the vestibule. Just deep to the areola, each lactiferousduct has a dilated region called a lactiferous sinus. The lobes are padded & separated from eachother by fibrous connective tissue & fat. No pregnancies or first pregnancy later in life. Family history of breast cancer (especially sister or mother). Developmentally, the mammary glands are modified sweat glands thatare really part of the skin, or integumentary system. 1056-1061) June 1, 1999‘Female Cycles & Fertilization’The monthly series of events associated with the maturation of an eggis called the ovarian cycle. The hymen is very vascular & tendsto bleed when it is ruptured during the first coitus (sexual intercourse). Slightly below the center of each breast isa ring of pigmented skin, the areola, which surrounds a central protrudingnipple. In virgins, the mucosa near the distal vaginal orifice forms anincomplete partition called the hymen.
