Question

Which specific cell type within the testis is primarily responsible for the synthesis and secretion of inhibin, a hormone that regulates FSH secretion?

K SUNKANNA · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
 **Primary Concept**: Testis cell function and hormonal regulation
 **Related Topics**: Endocrine system, reproductive physiology, spermatogenesis
 **Prerequisites**: Basic understanding of the male reproductive system and hormone feedback loops.
## SOLUTION PATHWAY
**Given Information**:
The question asks about the cell type responsible for inhibin production, a hormone that regulates FSH (follicle-stimulating hormone) secretion.
**Method & Steps**:
1. Identify the roles of different testicular cell types.
  Reasoning:  Each cell type in the testis has specific functions. We need to determine which one produces inhibin.
  Formula/Rule:  N/A
2. Recall the function of inhibin.
  Working: Inhibin is a hormone that acts on the anterior pituitary gland to negatively regulate the secretion of FSH.  This feedback loop helps maintain appropriate spermatogenesis.
  Key Point: The negative feedback loop ensures that FSH levels don't get too high, preventing overproduction of sperm.
3. Determine which cell type produces inhibin.
  Result: Sertoli cells are the primary source of inhibin in the testis.
  Verification: This is a well-established fact in reproductive physiology.
 ## OPTION ANALYSIS
A :x: Leydig cells are responsible for testosterone production.
B ✓: Sertoli cells nurture developing sperm and produce inhibin.
C :x: Spermatogonia are germ cells that undergo mitosis to produce spermatocytes.
D :x: Myoid cells provide structural support to the seminiferous tubules.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing Leydig cells with Sertoli cells:  Remember Leydig cells produce testosterone, while Sertoli cells produce inhibin and support spermatogenesis.
  2.Not understanding the negative feedback loop:  Inhibin's role is to prevent excessive FSH production.
 **Quick Tips**:
  1.Associate Sertoli cells with 'support' and 'inhibin'.
  2.Remember the acronym 'LIS' - Leydig cells produce testosterone, Inhibin from Sertoli cells.
