Enteric Nervous System: Regulation of GI Motor Activity

Enteric Nervous System: Regulation of GI Motor Activity

The Enteric Nervous System (ENS) plays a pivotal role in regulating gastrointestinal or GI motor activity. This complex network of nerves, deeply embedded within the gut wall, responds to changes in the gut environment and receives input from both the autonomic nervous system and the central nervous system. By doing so, the ENS operates various programs tailored to the body's nutritional status and needs.
During periods of fasting, the ENS initiates the migrating myoelectric complex, a program...

Nerve Supply of the GI Tract

Nerve Supply of the GI Tract

The neuronal supply to the gastrointestinal (GI) tract is essential for regulating various functions, including digestion, absorption, and movement of food. This intricate network of nerves is known as the enteric nervous system (ENS), often referred to as the "second brain" of the body.
The enteric nervous system consists of two major plexuses: the myenteric plexus (Auerbach's plexus) and the submucosal plexus (Meissner's plexus). These plexuses are located within the layers of the GI tract...

Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Physiology of Enteric Nervous System and Gut Health

Physiology of Enteric Nervous System and Gut Health

The gastrointestinal tract, responsible for the digestion and absorption of nutrients, is safeguarded by the intestinal barrier, which consists of secretory, physical, and immune components. At the forefront is the secretory barrier, composed of essential elements such as mucus, gut microbiota, and defense proteins. They collaborate to break down food particles, facilitate nutrient absorption, and maintain optimal gut health. These secretory components ensure the smooth functioning of the...

Functional Divisions of the Nervous System

Functional Divisions of the Nervous System

The nervous system, responsible for sensing, integrating, and responding to various stimuli, is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The PNS has two functional divisions: the sensory or afferent division and the motor or efferent division.
The sensory division transmits information from sensory receptors in the body to the CNS. It provides the CNS with knowledge about somatic senses (such as tactile, thermal, pain, and proprioceptive sensations)...

Gastric Motility

Gastric Motility

Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.
Peristaltic Waves and Chyme Formation
Upon food entry, the stomach initiates...

Area of Science:

Gastroenterology
Neuroscience
Cell Biology

Background:

The gut possesses an intrinsic nervous system, the enteric nervous system (ENS).
The ENS controls reflex behaviors, enabling gut function in isolation.
Mechanosensitive neurons within the ENS are crucial for encoding mechanical stimuli.

Purpose of the Study:

To review the concept of mechanosensitive enteric neurons as multifunctional.
To discuss stimulus modalities, response patterns, and functional roles.
To identify future research challenges in this area.

Main Methods:

Review of existing literature on mechanosensitive enteric neurons.
Analysis of electrophysiology, neurochemistry, and morphology data.
Synthesis of findings regarding neuronal function and circuit integration.

Main Results:

Mechanosensitive neurons respond to diverse mechanical stimuli (deformation, stretch).
These neurons exhibit varied electrophysiological and neurochemical properties, not belonging to a single specialized class.
Some mechanosensitive neurons are polymodal, responding to multiple stimulus types.

Conclusions:

Mechanosensitive enteric neurons are multifunctional, acting as 'multitaskers'.
They are integral components of multifunctional circuits within the ENS.
Further research is needed to fully elucidate their complex roles.
