Inferior pubic ramus

Last revised by Frank Gaillard on 27 Dec 2019

The inferior pubic ramus (plural: inferior pubic rami) is part of the pubis. It forms the border of the urogenital region of the pelvic outlet, running between the pubic tubercle and ischial tuberosity. 

Medial to the inferior pubic ramus lies the crus of the clitoris in females or penis in males. Superomedially lies levator ani muscle and directly superolateral is obturator internus muscle.  

Muscle attachments include the medial thigh muscles:
