Which one of the following statements best characterises the testis?

  • The seminiferous epithelium contains only proliferative cells

  • Functional compartmentalisation of the seminiferous epithelium depends on tight junctions

  • The interstitial tissue contains few capillaries

  • The seminiferous epithelium contains numerous capillaries

Solution

B.

Functional compartmentalisation of the seminiferous epithelium depends on tight junctions

Each testis contains seminiferous tubules for spermatogenesis and interstitial  (Intertubullar) tissue rich in Leyding cells for steroidogenesis seminiferous epithelium contains a continuous layer of the Sertoli cell, which are joined by tight intercellular junctions. These junctions divide the epithelium into a basal compartment that contains spermatogonia and an abdominal compartment.
