Seminiferous Tubule - an overview ScienceDirect Topics
There are two types: convoluted and straight, convoluted toward the lateral side, and straight as the tubule comes medially to form ducts that will exit the testis. The seminiferous tubules are formed from the testis cords that develop from the primitive gonadal cords, formed from the gonadal ridge. Function See more Seminiferous tubules are located within the testes, and are the specific location of meiosis, and the subsequent creation of male gametes, namely spermatozoa. See more The epithelium of the tubule consists of a type of sustentacular cells known as Sertoli cells, which are tall, columnar type cells that line the tubule. In between the Sertoli cells are spermatogenic cells, which differentiate through See more • Seminiferous tubule (right) with sperm (black, tiny, ovoid).

WebCross-Sections of Reproductive Tissue. Spermatogenesis in the seminiferous tubules starts at the outer lining of the tubule (germline epithelium) As the germ cells divide by meiosis they move towards the inner lining before being released into the lumen as sperm.
