Question

Give the function of

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

Answer 1

Answer:

here is your answer

Explanation:

A) A Sertoli cell (a kind of sustentacular cell) is a "nurse" cell of the testicles that is part of a seminiferous tubule and helps in the process of spermatogenesis, the production of sperm.

B)Leydig cells synthesise and secrete testicular hormones called androgens. ... The seminiferous tubules of the testis open into the vasa efferentia through rete testis. The vasa efferentia leave the testis and open into epididymis located along the posterior surface of each testis.

C)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.

Answer 2

Answer:

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.

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).

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.
