15.13 Human seminiferous tubule

Version française

Section showing an overall view of a human seminiferous tubule and its limiting membrane (My).

Various generations of germinal cells are labelled:

Spermatogonia (Ad and Ap) are seen along the limiting membrane.
The nuclei of primary spermatocytes (Sc), which form a second layer, are mixed with nuclei of Sertoli cells (S).
Nuclei of early round spermatids (St-a) and of late elongated spermatids (St-b) are present toward the centre of the tubule and occlude the lumen.

The nuclei of myoid cells (My) are seen in the limiting membrane.
