Question

Which of the following is the outermost protective layer of the testis, derived from the peritoneum?

Options

• Tunica Propria

• Tunica Vaginalis

• Tunica Albuginea

• Tunica Vasculosa

Answer 1

The tunica vaginalis is the outermost of the three protective layers (tunics) enclosing the testis. It is a double-layered serous membrane derived from the peritoneum. This layer provides a frictionless environment for testicular movement and contains serous fluid that reduces friction.
