Question

Which is not correct about sustentacular cells?
A.It is situated in between the germinal epithelial cells
B.It is related with nutrition of sperm
C.It forms blood testis barrier
D.It forms testosterone from oestrogen

Answer 1

Hint: A sustentacular cell is a kind of cell mainly correlated with structural assistance, they can be seen in several tissues. Sustentacular cells are benefiting cells of the seminiferous ducts of the testis; accountable for the differentiation of spermatids.

Complete answer:
Before we discuss the correct option. Let us know a little more about sustentacular cells. A sustentacular cell is a kind of cell that gives structural consent. They are of two categories. One type of cell is seen in the Sertoli cell, in the testicle of animals. It is existing in the fences of the seminiferous tubules and allocates nutrients to sperm as the sertoli cell is a nurse cell and another variety of cells are seen in the olfactory epithelium.
Option D: Sustentacular cells are benefiting cells of the seminiferous ducts of the testis; accountable for the differentiation of spermatids, the supervision of the blood-testis obstacle, and the secretion of inhibin, Mullerian-inhibiting factor and androgen-binding protein. They are not apprehensive with endocrine purposes of testes. Therefore, this is the correct option.
 The supporting cells (Sertoli) are found in the seminiferous ducts. Their chore is the innovation of a hematoma-testicular obstacle and the sustenance of the spermatozoa. They can barely proliferate in the early year of existence.

Hence, the correct answer is option (D)

Note: Sustentacular cells are found in the fences of the seminiferous ducts and store nutrients to sperm. They are accountable for the differentiation of spermatids, the supervision of the blood-testis obstacle, and the secretion of inhibitor, androgen-binding protein and Mullerian-inhibiting factor.
