Which of the following is correct location and function of Meissner's plexus of intestine?

Options

A. Muscularis externa - Peristalsis
B. Muscularis interna - Peristalsis
C. Submucosa - Mucosal secretions
D. Mucosa - Mucosal secretions

Answer

### Step-by-Step Text Solution:

1. **Understanding the Structure of the Intestinal Wall**:
- The intestinal wall consists of four layers:
- **Cirrhosa** (outermost layer)
- **Muscularis** (divided into two layers: outer longitudinal muscle layer (LML) and inner circular muscle layer (CML))
- **Submucosa** (contains connective tissue, blood vessels, and nerves)
- **Mucosa** (innermost layer involved in absorption)

2. **Identifying the Location of Meissner's Plexus**:
- Meissner's plexus, also known as the submucosal plexus, is located between the circular muscle layer (CML) and the submucosa. This is crucial for understanding its function.

3. **Understanding the Function of Meissner's Plexus**:
- The primary function of Meissner's plexus is to regulate glandular secretion in the gut. It controls the secretion of digestive enzymes and other substances from the mucosal glands.

4. **Evaluating the Given Options**:
- The question likely provides multiple-choice options regarding the location and function of Meissner's plexus.
- Based on the information:
- The correct location is between the CML and submucosa.
- The correct function is to control glandular secretion.

5. **Conclusion**:
- The correct answer would be the option that states the location of Meissner's plexus as being in the submucosa and its function as controlling mucosal secretion.
