seminiferous tubules

sem·i·nif·er·ous tu·bules

one of two to four twisted, curved tubules in each lobule of the testis, in which spermatogenesis occurs. Synonym(s): tubuli seminiferi recti [TA], convoluted seminiferous tubule, tubuli contorti (2)

seminiferous tubules

The many, long, coiled-up, fine tubes, hundreds of which are present in each testicle and are said to total in length over 400 m. The spermatozoa develop from cells in the walls of these tubules.

seminiferous tubules

coiled tubules in which SPERMATOGENESIS takes place in the testes of male vertebrates. They are made up of germinal epithelium and hundreds are present in each testis. The germ epithelium proliferates, forms spermatogonia and grows into spermatocytes which give rise to spermatids by GAMETOGENESIS. The spermatids mature to spermatozoa embedded in nutritive SERTOLI CELLS.
