It has a branch which is the inferior rectal artery which supplies the distal rectum and anal canal.

Question 11

Question 15

What are the boundaries of the lesser sciatic foramen?

Answer 15

Anterior: tuberosity of the ischium
Superior: the spine of the ischium and sacrotuberous ligament
Posterior: the sacrotuberous ligament

Question 16

What are the boundaries of the greater sciatic foramen?

Answer 16

Anterolaterally: the greater sciatic notch of the ischium.
Posteromedially: The sacrotuberous ligament
