A) Leydig cells
B) Scrotum
C) Sertoli cells
D) Epididymis
Correct Answer: C
Solution :
Sertoli cells are named after its discoverer, an Italian histologist Enrich Sertoli (1842-1910 These are located in seminiferous tubule. Sertoli cells secrete Androgen Binding Protea (ABP) that concentrates testosterone in seminiferous tubules. It acts as a nurse cells for differentiating Spermatozoa. Sertoli cells are also known as subtenticular cells. These are characteristics of mammalian testis. Sertoli cells mainly nourish the spermatozoa (sperm). Leydig cells are named so after a German anatomist, Franz von Leydig (1821-1908) who discovered them. These cells secrete testosterone hormone that controls spermatogenesis. Scrotum is pouch of deeply pigmented skin divided into two separate sacs. The normal temperature of the testes in the scrotum is about\[{{2}^{o}}\]lower than the internal body temperature and is the ideal temperature for developing sperms. Epididymis is a mass of long narrow closely coiled tubule, which lies along the inner side of each testis.
