Exocrine Cells of Testes
View Complete Answer & Explanation
Question (English)
Exocrine cells of the testes are:
- Sertoli cells only
- Germ cells only
- Both Sertoli cells and Germ cells ✓ Correct
- Leydig cells
Explanation:
Correct Answer: Both Sertoli cells and Germ cells
The exocrine cells of the testes include both Sertoli cells and Germ cells, as both are components of the seminiferous tubule and contribute to spermatogenesis — a process whose products (spermatozoa) are delivered via ducts (exocrine secretion).
Seminiferous Tubule Components
- Germ cells: Undergo spermatogenesis → produce spermatozoa
- Sertoli cells (Sustentacular/Nurse cells): Support, nourish and protect developing sperm; secrete AMH, Inhibin and ABP
Endocrine vs Exocrine of Testes
- Endocrine: Leydig cells → secrete testosterone into blood
- Exocrine: Sertoli + Germ cells → contribute to spermatozoa production and secretion through tubular system
