Production of gastro-intestinal secretions and movment soon after ingestion of food are brought about by

Options

A. Central nervous system
B. Sympathetic nervous system
C. Parasympathetic nervous system
D. Preipheral nernous system

Answer

To answer the question regarding the production of gastrointestinal secretions and movements soon after ingestion of food, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Gastrointestinal Secretions**:
- Gastrointestinal secretions include saliva, gastric juices, pancreatic juices, and bile. These secretions are essential for the digestion of food.

2. **Role of the Nervous System**:
- The nervous system plays a crucial role in regulating these secretions and the movement of food through the digestive tract.

3. **Identifying the Relevant Nervous System Components**:
- The central nervous system (CNS) includes the brain and spinal cord.
- The sympathetic nervous system is responsible for the 'fight or flight' response and generally inhibits digestive processes.
- The parasympathetic nervous system promotes 'rest and digest' activities, enhancing digestion and absorption.
- The peripheral nervous system encompasses all nerves outside the CNS, including both sympathetic and parasympathetic systems.

4. **Impact of the Parasympathetic Nervous System**:
- When food is ingested, the parasympathetic nervous system is activated. This leads to:
- Increased secretion of gastric juices.
- Enhanced secretion of saliva and pancreatic juices.
- Increased peristalsis (the wave-like muscle contractions that move food through the digestive tract).

5. **Conclusion**:
- Based on the above points, the correct answer to the question is **C. Parasympathetic nervous system**. This system is primarily responsible for stimulating the production of gastrointestinal secretions and facilitating movement in the digestive tract soon after food ingestion.

### Final Answer:
The production of gastrointestinal secretions and movements soon after ingestion of food are brought about by **C. Parasympathetic nervous system**.
