- STST p. 478-479 The pelvic girdle consists of the iliac crest, ischia, pubic bones, and sacrum; it’s attached to the vertebral column at the sacrum.
- A & P Overview (Know the words in RED in STST) Conditions arising from dysfunction of the pelvic musculature which relate to GYN surgery include prolapse of internal organs, such as of the bladder or rectum, into the vaginal vault. Surgically, these organs are approached using various techniques by incision into the spaces that surround and divide them. These anatomical planes are called the prevesical, vesicovaginal, vesicocervical, and rectovaginal spaces. The perineum is the area between the vaginal opening and the anus. It is generally 2-3 cm in length and is supported by the peliv and urogenital diaphagms, which consist of the levator ani, coccygeal, and deep transverse perineal muscles. (See Appendix A Plate 2, p. 1026. The vestibule is the cavity between the labia minora, and it contains the urethra meatus, inferior to the clitoris, as well as the orifaces of the vestibular glands (or Bartholin’s glands). So—the Bartholin’s glands are located within the vestibule . What are they? Paired structures about 0.5-1 cm in diameter that secrete a lubricating mucoid substance.
- STST p. 479 The structures of the pelvic outlet relate to the function of childbearing. The pelvis can be divided into 2 cavities: the superior and the inferior cavity. The superior is the “false pelvis” and the inferior is the “true pelvis” which has a pelvic inlet and pelvic outlet thru which the fetus passes during childbirth. This shallower and wider outlet aids in the process of fetal delivery.
- Fig 15-4: p. 479 The pelvic ligaments lend support to the pelvic organs and help maintain the relative positions of the organs in the lesser pelvis. The pelvic ligaments, which include the cardinal, round, and infundibulopelopelvic ligaments, are loose configurations of areolar tissue, blood vessels, and muscle tissues that act as “moorings” for the uterus and vagina. Connective tissue helps to keep the structural integrity of the organs in stasis. Connective tissue change with age, nutritional status, amt of exercise, and hormonal fluctuations.
- STST p. 482 Vagina: p. 481/482: The vaginal mucosa becomes thicker at puberty and is enriched with glycogen that supports a normal flora that renders vaginal fluid acidic— so pH is acidic . Another name for the fallopian tubes and ovaries (together) are the adnexa, or the uterine appendages . Another name for fallopian tubes are uterine tubes. The uterus is lined with endometrium that varies in its consistency an sheds in accordance with phases of the menstrual cycle. Ligaments extending to the pelvic walls suspend the uterus: broad, cardinal, pubic, sacral. The broad ligament contains the uterine folds, contains the uterine (fallopian) tube, the round and ovarian ligaments, and various blood vessels, nerves, and lymphatics. The ovaries are supported at either end by ligaments. A fold of peritoneum arising near the overlying fimbria forms the suspensory ligament. The ovarian ligament, lying in the broad ligament, supports the bulk of the ovary. Blood arrives to the organs via the ovarian arteries branching from the aorta and follows ovarian veins back to the inferior vena cava.

- This—out of Lemone and Burke Ch 48: Types of Uterine fibroid tumors –also called leiomyomata). Leiomyomata are benign tumors that originate from smooth muscle of the uterus. The are the most common form of pelvic tumor, believed to occur n 1 of every 4 or 5 women older than 35 yrs of age. Fibroid tumors usually develop in the uterine corpus, and may be intramural, subserous, or submucous. Intramural fibroid tumors lie within the uterine wall. Subserous fibroid tumors lie beneath the serous lining of the uterus and project into the peritoneum. Submucous fibroid tumors lie beneath the endometrial lining of the uterus. Fibroids are seen more often and grow more rapidly in African Americans. Myomectomy—removal of the tumor without removing the entire uterus, is the surgical procedure of choice for women who which to retain productive capability.
