    Spermatic cord structure

    Fibrous cord containing blood vessels, nerves, and the vas deferens, passing through the inguinal canal in males.

    Gubernaculum function

    Fibrous cord attaching the gonad to the future scrotum or labia, aiding in the descent of the testicles.

    Direct inguinal hernia

    Hernia directly through the abdominal wall, often weakness in the posterior inguinal ring.

    Mesentery definition

    Double-layered peritoneum enveloping blood vessels and nerves supplying an organ. It's mobile.
