What structure is formed by the draining veins of the scrotum, nerves, and lymphatics?

The spermatic cord is a significant anatomical structure that contains the arteries, veins, nerves, and lymphatics supplying the testis and the scrotum. It serves as a conduit between the scrotum and the abdominal cavity, carrying vital elements such as the ductus deferens, testicular artery, pampiniform plexus of veins (which drain the scrotum), and various nerves. The presence of these components within the spermatic cord allows for thermoregulation of the testis and plays a role in the support and function of the reproductive system.

The inguinal canal, while related to the passage of the spermatic cord, is primarily a passageway that the cord follows rather than a structure formed by its components. The fascial layer provides support and structure but does not encompass the draining veins, nerves, and lymphatics in the way that the spermatic cord does. The scrotal ligament is a structure that helps anchor the testis but does not encompass the complex arrangement of vessels and nerves present in the spermatic cord. Thus, the spermatic cord is the fitting answer as it integrates all these essential elements together, facilitating their function and connectivity.
