Contents of inguinal canal are all except
**Core Concept**
The inguinal canal is a narrow, tortuous passage in the anterior abdominal wall through which the spermatic cord in males and the round ligament of the uterus in females pass. It is an important anatomical structure that provides a conduit for the transport of various structures, including nerves, blood vessels, and lymphatic vessels.
**Why the Correct Answer is Right**
The correct answer is the structure that is not typically found within the inguinal canal. The inguinal canal contains the spermatic cord in males, which includes the vas deferens, testicular arteries, and cremasteric arteries. In females, the round ligament of the uterus passes through the inguinal canal. The inguinal canal also contains the ilioinguinal nerve, which provides sensory innervation to the skin of the medial thigh and the root of the penis in males, and the labia majora in females.
