Describe the structure of a seminiferous tubule.

Explanation

Seminiferous tubules are highly coiled tubular structures present in testicular lobules of testis. The wall of each seminiferous tubule is lined by germinal epithelium. Majority of cells of this epithelium are cuboidal called male germ cells (spermatogonia), but a few large cells called Sertoli cells or sustentacular cells. The male germ cells grow into primary spermatocytes,which undergo meiosis to produce spermatozoa.
