Which hormone stimulates contraction of gall bladder :

Options

A. CCK-
B. ACTH
C. LH
D. FSH

Answer

**Step-by-Step Solution:**

1. **Identify the Hormones Listed**: The question provides four hormones: CCK (Cholecystokinin), ACTH (Adenocorticotropic Hormone), ALAGE, and APHYSIT.

2. **Understand the Function of Each Hormone**:
- **CCK (Cholecystokinin)**: This hormone is secreted by the enteroendocrine cells in the gastrointestinal tract. It plays a crucial role in digestion.
- **ACTH (Adenocorticotropic Hormone)**: This hormone stimulates the adrenal cortex to release cortisol and does not have a direct role in gallbladder contraction.
- **ALAGE and APHYSIT**: These hormones are not commonly recognized in the context of gallbladder function or hormonal regulation.

3. **Determine the Role of CCK**: Cholecystokinin is specifically known to stimulate the contraction of the gallbladder. When food enters the small intestine, CCK is released, which causes the gallbladder to contract and release bile into the intestine.

4. **Conclude the Correct Answer**: Based on the functions of the hormones discussed, the hormone that stimulates the contraction of the gallbladder is CCK (Cholecystokinin).

5. **Final Answer**: The correct option is CCK (Cholecystokinin).
