Section Of Uterus And Vagina

The oocyte is ovulated from the ovary and moves into the uterine tube. The uterine tube is fringed by small cylindrical structures called fimbriae. The uterus is a small, flask-shaped organ. The uterus has a domed fundus, a main body, a narrowed isthmus, and an inferior cervix. The uterosacral ligament attaches the uterus to the sacrum. Most of the uterine wall is made of the myometrium which is a thick layer of smooth muscle. The vagina is approximately ten centimeters in length and is lined with stratified squamous epithelium and smooth muscle. A small ring of mucous membrane called the hymen is present in the vagina and is frequently torn during first intercourse. The hymen can rupture prior to intercourse and is not a good indicator of virginity. The vagina has rugae which are folds in the vaginal wall. These stimulate the penis and also allow for expansion of the vagina during delivery. Label the suspensory ligament and ovarian ligament as well as the structures of the uterus, ovary, and vagina. Color the regions of the uterus, ovary, vagina, and associated structures.

The mammary glands are located in the breast. They produce milk when a woman is lactating and lead to lactiferous ducts. These ducts take milk to the lactiferous sinuses which drain into the nipple. Because breast cancer is a significant cause of mortality in women, the lymph drainage of the breast is important. Primary tumors may originate in the breast tissue and then migrate by lymphatic vessels to the axillary lymph nodes. This is one of the main ways that breast cancer spreads. There is a small series of parasternal lymph nodes that takes a small portion of the lymph back to the cardiovascular system.

The floor of the pelvis is known as the perineum and can be divided into a urogenital triangle and an anal triangle. The anal triangle contains the anus and the urogenital triangle houses the vaginal orifice, the urethral orifice, and the clitoris. The mons pubis is the most anterior part of the external genitalia and posterior to that is the prepuce. This structure envelops the clitoris. The labia majora and the labia minora encircle the vaginal orifice. The vagina is lubricated internally by some glands during arousal and intercourse as well as from the greater vestibular glands located laterally and posteriorly to the vaginal orifice. Label the structures of the female breast and the external genitalia and color them in.
