Which cells in the seminiferous tubules provide structural and nutritional support to developing germ cells?
Correct answer: A. Sertoli cells
- A. Sertoli cells
- B. Leydig cells
- C. Peritubular myoid cells
- D. Epididymal principal cells
Explanation
Sertoli cells support developing sperm cells, form the blood-testis barrier, and help regulate spermatogenesis. Leydig cells lie in the interstitial tissue and primarily produce testosterone, so they are a common trap.
