Autonomous Nervous System and Peristalsis of the Intestine
Autonomous nervous system is a part of the peripheral nervous system that is responsible for regulating the involuntary functions of the body. It can be further divided into the sympathetic and parasympathetic nervous systems.
Peristalsis is the involuntary contraction of smooth muscles that propels food through the digestive tract. The autonomous nervous system plays a crucial role in regulating the peristaltic movement of the intestine.
Role of Parasympathetic Nervous System in Peristalsis
The parasympathetic nervous system is responsible for the rest and digest response of the body. It stimulates the peristaltic movement of the intestine by releasing the neurotransmitter acetylcholine. This neurotransmitter acts on the smooth muscles of the intestine and causes them to contract.
Role of Sympathetic Nervous System in Peristalsis
The sympathetic nervous system is responsible for the fight or flight response of the body. It inhibits the peristaltic movement of the intestine by releasing the neurotransmitter norepinephrine. This neurotransmitter acts on the smooth muscles of the intestine and causes them to relax.
Conclusion
Thus, peristalsis of the intestine is an example of the action of the autonomous nervous system, specifically the parasympathetic nervous system. It shows how the nervous system regulates the involuntary functions of the body.
