Give the function of
A)Sertoli cells
B)Leydig's cells
C) Trophoblast
Answers
Explanation:
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).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.
tq for saying ill mark as brainleist and what is ur name❤
Answer:
Sertoli cells
Sertoli cells facilitate the progression of germ cells to spermatozoa via direct contact and by controlling the environment milieu within the seminiferous tubules. The regulation of spermatogenesis by FSH and testosterone occurs by the action of these hormones on the Sertoli cells.
Leydig's cells
Leydig cells synthesise and secrete testicular hormones called androgens.
Trophoblast
It is a precursor of the placenta. …of the morula become the trophoblast and the inner cell mass gives rise to the embryo (the formative cells) and also its yolk sac, amnion, and allantois. A cavity appears within the morula, converting it into a hollow embryo, called the blastocyst.
