Which one of the following statements best characterise the testis?

  • A
    The seminiferous epithelium contains only proliferative cells
  • Correct answer
    B
    Functional compartmentalisation of the seminiferous epithelium depends on tight junctions
  • C
    The interstitial tissue contains few capillaries
  • D
    The seminiferous epithelium contains numerous capillaries

Solution

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

Hence, the correct answer is option: 'B'.
