Introduction to the female pelvic cavity
After working through this study unit you will be able to:
- Identify the major structures that form the walls and floor of the female pelvic cavity.
- Recognize the major blood vessels that supply and drain the female pelvic cavity.
- Name the various organs of the female pelvic cavity.
- Understand the anatomical relations and functions of these organs.
The female pelvic cavity is bounded by bony and musculoligamentous pelvic walls and floor. It contains several organs from the digestive, reproductive and urinary systems, some of which pass into the perineum. These include the:
- terminal part of the sigmoid colon, which continues distally as the rectum
- ovaries, uterine tubes and uterus
- pelvic part of the ureters and urinary bladder
The female pelvic organs are surrounded by pelvic visceral fascia. Additionally, the parietal peritoneum of the abdominal cavity reflects onto the superior surfaces of some of these organs, forming pouches between adjacent organs. The pelvic floor is formed by a musculofascial pelvic diaphragm composed of the levator ani and coccygeus muscles, that separates the pelvic cavity above from the perineum below.
The female pelvic cavity is supplied by various branches of the internal iliac artery, the superior [ano]rectal artery and the median sacral artery, with the ovary receiving the ovarian artery from the abdominal aorta. Various visceral plexuses carry both sympathetic and parasympathetic fibers that provide innervation to the organs as well as visceral afferent fibers which mostly carry pain sensation to the central nervous system.
This video will help you learn about the anatomy and contents of the female pelvic cavity in detail.
