Question

What is the composition of the tunica albuginea?

Options

• Germinal epithelium with spermatogonia

• Vascular tissue with blood vessels

• Serous membrane derived from peritoneum

• Dense white fibrous connective tissue with collagen fibres

Answer 1

The tunica albuginea is the middle protective layer of the testis and is composed of dense white fibrous connective tissue rich in collagen fibres. This tough, fibrous composition provides structural support and protection to the testis while allowing inward projections (septa) to partition the organ into its characteristic lobular structure.
