Seminiferous tubule. Light micrograph of a section through a testis showing part of a seminiferous tubule. The seminiferous tubules are the site of sperm production (spermatogenesis). Sperm cells are made up of a head,containing genetic material,and a tail. Mature sperm cells can be seen closest to the tubule's lumen (upper centre,white). Moving away from the lumen are increasingly immature precursor cells; first spermatids,then spermatocytes and finally spermatogonia. The outermost cells are sertoli cells,which nourish the maturing sperm | |
