How are the activities of gastro-intestinal tract regulated?

Explanation

**Step-by-Step Solution:**

1. **Understanding Regulation of Gastrointestinal Tract Activities**: The activities of the gastrointestinal (GI) tract are regulated through two primary mechanisms: neural control and hormonal control.

2. **Neural Control**:
- The neural control involves the nervous system, which influences the digestive process through specific neurotransmitters.
- **Acetylcholine**: This neurotransmitter is released by the parasympathetic nervous system and plays a crucial role in stimulating the secretion of digestive juices, enhancing digestion.
- **Adrenaline**: In contrast, adrenaline, which is associated with the sympathetic nervous system, inhibits the secretion of digestive juices. This highlights the opposing effects of the two branches of the autonomic nervous system.
