Question

Which of the following correctly pairs a cell type with its location in or around the seminiferous tubules?

Options

• Spermatids located outside the seminiferous tubules

• Sertoli cells located at the periphery along the basement membrane

• Leydig cells located in interstitial spaces between tubules

• Spermatogonia located in interstitial spaces between tubules

Answer 1

Leydig cells, also known as interstitial cells, are located in the interstitial spaces between seminiferous tubules. In contrast, spermatogonia are located at the periphery along the basement membrane, and Sertoli cells line the wall of the seminiferous tubules. This spatial organization is critical for coordinating hormone signaling and germ cell development.
