Which one of the following statements best characterise the testis?
Options
- AThe seminiferous epithelium contains only proliferative cells
- BFunctional compartmentalisation of the seminiferous epithelium depends on tight junctions
- CThe interstitial tissue contains few capillaries
- DThe seminiferous epithelium contains numerous capillaries
Correct answer
B. Functional compartmentalisation of the seminiferous epithelium depends on tight junctions
Step-by-step 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.
