Solution
The correct option is C Seminiferous tubules
Seminiferous tubule is the functional unit of testis of man. Each testis has about 250 compartments called testicular lobules, these compartments contain highly coiled tubules called seminiferous tubules. In seminiferous tubules, sperms are produced. Each seminiferous tubule is lined on its inside by two types of cells called male germ cell (spermatogonia) and Sertoli cells. These cells are also called nurse cells as they provide nutrition to the developing sperms. Head of developing sperms are embedded in the sertoli cells. The male germ cells undergo meiotic divisions finally leading to sperm formation.Thus, the correct answer is 'Seminiferous tubules'.
