Seminiferous tubule SEM

Seminiferous tubules are located in the testes, and are the specific location of meiosis, and the subsequent creation of gametes, namely spermatozoa.
The epithelium of the tubule consists of sustentacular or Sertoli cells, which are tall, columnar type cells that line the tubule.
