Question

The nurse cells of the seminiferous tubules do all of the following, except that they

A) maintain the blood-testis barrier.
B) secrete androgen-binding protein.
C) secrete inhibin.
D) support spermiogenesis.
E) secrete testosterone.

Answer 1

Sertoli cells, or nurse cells, perform several functions in support of sperm production, but they do not secrete testosterone.

Step-by-step explanation:

Sertoli cells, also known as nurse cells, are found in the seminiferous tubules and play a crucial role in spermatogenesis.

They perform various functions to support the process of sperm production, including maintaining the blood-testis barrier, secreting androgen-binding protein, and supporting spermiogenesis. However, Sertoli cells do not secrete testosterone. This hormone is primarily secreted by the interstitial cells of Leydig, which are located in the wall of the seminiferous tubules.
