The neural plexus that controls the secretions of organs of the GI tract is

Options

A. Myenteric plexus
B. Submucosal plexus
C. Brachial plexus
D. Cervical plexus

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the neural plexus that controls the secretions of the organs of the gastrointestinal (GI) tract.

2. **Identifying the Options**: The options provided are:
- A) Myenteric plexus
- B) Submucosal plexus
- C) Brachial plexus
- D) Cervical plexus

3. **Defining Plexus**: A plexus is a network or bundle of nerves that can control various functions in the body. In the context of the GI tract, we are interested in which plexus regulates secretions.

4. **Understanding the GI Tract**: The GI tract includes the mouth, esophagus, stomach, intestines, and ends at the rectum and anus. Each part has specific functions, including secretion of digestive juices.

5. **Analyzing the Plexuses**:
- **Myenteric Plexus**: Located between the layers of the muscularis, it primarily controls the motility (movement) of the GI tract, not secretion.
- **Submucosal Plexus**: Found in the submucosal layer, it is responsible for regulating the secretions of the GI tract. This plexus is also known as Meissner's plexus.
- **Brachial Plexus**: This plexus is located in the shoulder region and controls the upper limbs; it is not related to the GI tract.
- **Cervical Plexus**: This plexus is found in the neck region and controls functions related to the neck and upper part of the body, not the GI tract.

6. **Conclusion**: Based on the analysis, the correct answer is **B) Submucosal plexus**, as it specifically regulates the secretions of the organs in the GI tract.
