Question

Sertoli cells are found in

• A. Adrenal cortex and secrete adrenaline
• B. Seminiferous tubules and provide nutrition to germ cells
• C. Pancreas and secrete cholecystokinin
• D. Ovaries and secrete progesterone

Answer 1

The Correct Option is B

Sertoli cells are a crucial component of the male reproductive system. Here's a detailed explanation of their location and function:

1. Location of Sertoli Cells: Sertoli cells are located within the seminiferous tubules of the testes. These tubules are the sites of sperm production, also known as spermatogenesis.
2. Function of Sertoli Cells: Sertoli cells play a vital role in nurturing and supporting the development of germ cells (sperm cells) as they mature from spermatogonia into spermatozoa. They provide both nutritional and structural support.
3. Ruling Out Other Options:
   • Adrenal cortex: The adrenal cortex secretes steroid hormones like cortisol and aldosterone, not adrenaline.
   • Pancreas: While the pancreas produces various hormones (e.g., insulin), it does not secrete cholecystokinin; that is a function of the small intestine.
   • Ovaries: The ovaries are involved in female reproductive functions, secreting hormones such as estrogen and progesterone. They contain different cell types unrelated to Sertoli cells.
4. Conclusion: Based on the above explanations, Sertoli cells are correctly identified as being located in the seminiferous tubules where they provide nutritional support to developing germ cells. Thus, the correct answer is: Seminiferous tubules and provide nutrition to germ cells.
