Different types of supportive cells in human testis are involved inI. The production of testosterone.II. Providing structural and metabolic support to spermatogenic cells.III. Providing nourishment to the developing sperms.The function(s) of sertoli cells is/ are
Correct answer: D. II and III
- A. I only
- B. II only
- C. I and II
- D. II and III
Explanation
The correct answer is II and III. Sertoli cells are responsible for providing structural and metabolic support to spermatogenic cells and also nourish developing sperm cells. Option I is incorrect because the production of testosterone is primarily the function of Leydig cells, not Sertoli cells. Option B is incorrect because it only includes one of the functions of Sertoli cells. Option C is incorrect because it includes the erroneous function of testosterone production.
