Write a note on seminiferous tubules.

Text Solution

Verified by Experts

Each testicular lobule contains 1-3 highly coiled seminiferous tubules. Each tubule is lined on its inside by two types of cells.
The cuboidal cells are called male germ (spermatogenic) cells and few large pyramidal (supporting cells–Sertoli or Nurse cells).
The former gets divided to form sperms while the latter provides nutrition to the germ cells.
