MEDICAL PHYSIOLOGY

Detailed explanation-1: -[1] The ‘tendinous’ anatomy of the inguinal ligament, stretching from the anterior superior iliac spine (ASIS) to the pubic tubercle (PT) with its grooved superior surface, was later discussed in detail by Cunningham. It forms by the folding of the inferior extent of the external oblique aponeurosis.

Detailed explanation-2: -The walls of the inguinal canal include the following: An anterior wall that is composed of the aponeurosis of the external oblique muscle and reinforced laterally by the internal oblique muscle. The superficial inguinal ring also contributes to the medial third.

Detailed explanation-3: -The conjoint tendon forms the medial part of the posterior wall of the inguinal canal. [3] It is located right behind the superficial inguinal ring. The inguinal canal is a small passage formed by aponeuroses of the abdominal musculature.

Detailed explanation-4: -The conjoint tendon is formed from the lower part of the common aponeurosis of the abdominal internal oblique muscle and the transversus abdominis muscle. It inserts into the pubic crest and the pectineal line immediately behind the superficial inguinal ring.
