END 1 Lab 3: Female Pelvis and Genitalia

Module 2 - Nerves, Vessels and Lymphatic Drainage: Page 3 of 7

	Add the pudendal nerve and trace its path from the sacrum (sacral plexus) to the pelvic diaphragm and its termination in the perineum. You will have to rotate the pelvis to view the entire path of the nerve. (TIP: If you have trouble finding the pudendal nerve, use the Anatomy Icon and find the pudendal nerve in the index. Turn the "Sun" off and on as you watch the pelvis.)

	Through what foramen does the pudendal nerve pass in order to reach the perineum?
The pudendal nerve exits the pelvis through the greater sciatic foramen, curves around the sacrospinous ligament, and reenters the perineum through the lesser sciatic foramen.

	What are the three terminal branches of the pudendal nerve?
Inferior rectal nerve Perineal nerve Dorsal nerve of the clitoris (or penis)

	Where would you adminster the pudendal nerve block for pain control (e.g., during childbirth)?
The injection is typically placed near the ischial spine, just medial to the sacrospinous ligament, using transvaginal palpation as a landmark. Rotate the 3D model so you can see these relationships.
