Describe the structure of a seminiferous tubule.
The manufacturing of sperms withinside the testes takes vicinity in a noticeably coiled shape referred to as the seminiferous tubules. These tubules are placed withinside the testicular lobules. Each seminiferous tubule is covered with the aid of using germinal epithelium. It is covered on its internal aspect with the aid of using styles of cells specifically spermatogonia and sertoli cells respectively. Spermatogonia are male germ cells which produce number one spermatocytes with the aid of using meiotic divisions. Primary spermatocytes go through in addition meiotic department to shape secondary spermatocytes and finally, spermatids. Spermatids later metamorphoses into male gametes referred to as spermatozoa. Sertoli cells are referred to as nurse cells of the testes as they offer nourishment to the germ cells. There are big polygonal cells called interstitial cells or leydig cells simply adjoining to seminiferous tubules. These cells secrete the male hormone referred to as testosterone.
