A structure located on the posterior border of the testis courses between the abdominal cavity and scrotum through the inguinal canal and contains arteries, veins, nerves, lymphatics, seminal duct, fatty and connective tissue.

A structure located on the posterior border of the testis courses between the abdominal cavity and scrotum through the inguinal canal and contains arteries, veins, nerves, lymphatics, seminal duct, fatty and connective tissue.

• A. Spermatic cord
• B. Cremasteric muscle
• C. Vas deferens
• D. Pampiniform plexus

Answer: (A)

The structure described is the spermatic cord. It travels from the abdominal cavity through the inguinal canal and into the scrotum, located along the posterior aspect of the testis. Within this cord are the vas deferens (seminal duct), the testicular arteries, the pampiniform venous plexus, lymphatics, autonomic nerves, and surrounding fatty and connective tissue. This bundle is precisely the collection of vessels, nerves, ducts, and tissues that the description lists, making it the best fit for the given scenario. The alternatives don’t fit as completely: the cremasteric muscle is a muscle layer that helps raise the testis but does not contain the full set of vessels, nerves, and the duct. The vas deferens is just the conduit for sperm and does not include arteries, veins, lymphatics, or nerves. The pampiniform plexus is only the venous network draining the testis and lacks the arterial supply, duct, and other components found in the cord.
