Conjoint tendon

It forms the medial part of the posterior wall of the inguinal canal.

[1] It inserts into the pubic crest and the pectineal line immediately behind the superficial inguinal ring.

[1] The conjoint tendon serves to protect what would otherwise be a weak point in the abdominal wall.

[1] A weakening of the conjoint tendon can precipitate a direct inguinal hernia.

The conjoint tendon is also known as the inguinal aponeurotic falx, and Henle's ligament.
