Question

Which is the partial content of the inguinal canal ? Why ?

Answer 1

Ilioinguinal nerve is considered as the partial content of the inguinal canal.
This nerve is said to be the partial content of inguinal canal because it enters the canal through roof by piercing the internal oblique muscles and leaves the canal through the superficial inguinal ring. The ilioinguinal nerve does not pass through the deep inguinal ring, and thus only travels through part of the inguinal canal.
Ilioinguinal nerve is a mixed nerve. The nerve enters the canal by piercing the internal oblique muscle about 2.5 cm. below and medial to the anterior superior iliac spine. It is situated superficial to the spermatic cord, and leaves the canal through superficial ring. Ilio- Inguinal nerve conveys fibres from the ventral ramus of L1, but after piercing the internal oblique it conveys sensory fibres only.
