**Autonomous Neural System**
The autonomous neural system, also known as the autonomic nervous system, is responsible for controlling unconscious bodily functions such as heart rate, digestion, and respiratory rate. It is further divided into the sympathetic and parasympathetic nervous systems, which work in opposition to regulate various bodily functions.
**Examples of Autonomous Neural System Actions**
Below are some examples of the actions controlled by the autonomous neural system:
- **Swallowing of Food:** When we swallow food, the autonomous neural system coordinates the movements of the muscles involved in the swallowing process. This involves a combination of voluntary and involuntary muscle actions to move the food from the mouth to the stomach.
- **Pupillary Reflex:** The autonomous neural system controls the pupillary reflex, which is the automatic constriction or dilation of the pupils in response to changes in light intensity. This reflex helps regulate the amount of light entering the eye to maintain optimal vision.
- **Peristalsis of the Intestine:** Peristalsis is the involuntary wave-like muscle contractions that propel food and waste through the digestive tract. The autonomous neural system controls the rhythmic contractions of the smooth muscles in the intestines to facilitate digestion and absorption of nutrients.
**Conclusion**
In conclusion, the autonomous neural system plays a crucial role in regulating various bodily functions without conscious effort. The examples mentioned above demonstrate how this system controls essential processes such as swallowing, pupillary reflex, and peristalsis. Understanding the actions of the autonomous neural system is essential for comprehending the complex mechanisms that govern our bodies.
