Question

Sertoli cells occur in

• A. Frog testis
  
• B. Human testis
  
• C. Human ovary
  
• D. Frog ovary
  

Answer 1

The correct option is B Human testis


Sertoli cells
Sertoli cells or nurse cells present in the seminiferous tubules inside the testes. They provide nourishment to the developing spermatozoa.

Human testes
Human testes contain sertoli cells in the seminiferous tubules. They provide nourishment to developing sperms.

Frog testes
Sertoli cells or nurse cells help in the nourishment of sperms which are absent in testes of frogs.

Ovary
Sertoli cells are present in testes and not in ovaries. Hence both the human and frog ovaries do not have sertoli cells.

Granulosa cells are present in the ovary of humans which are analogous to sertoli cells. They support the follicle development and developing oocytes.

Final answer
(A) Human testis
