Question

Give the function of

A)Sertoli cells
B)Leydig's cells
C) Trophoblast​

Answer 1

Explanation:

A) Sertoli cells are the somatic cells of the testis that are essential for testis formation and spermatogenesis. Sertoli cells facilitate the progression of germ cells to spermatozoa via direct contact and by controlling the environment milieu within the seminiferous tubules.

B) Leydig cells are interstitial cells located adjacent to the seminiferous tubules in the testes. The best-established function of Leydig cells is to produce the androgen, testosterone, under the pulsatile control of pituitary luteinizing hormone (LH) (9).

C) 38.3.

38.3.Trophoblasts are cells that form the outer layer of a blastocyst, which provides nutrients to the embryo, and then develop into a large part of the placenta. Trophoblast invasion is a critical process in the establishment of a successful pregnancy.
