15.5 Seminiferous tubule

Version française

Cross section of a human seminiferous tubule.

Between the limiting membrane (M) and the tubular lumen (*) is a complex stratified epithelium.

This epithelium is composed of two main classes of cells: the supporting non-dividing somatic Sertoli cells (S) (see figures 15.10–15.13), and the germinal cells at various steps of spermatogenesis: spermatogonia (Sg), spermatocytes (Sc) and spermatids (St).

The limiting membrane (M) is composed of flattened contractile cells or myoid cells separated by a small amount of connective tissue fibrils (collagen, elastin, fibrilin and reticulin).
