|May 9, 2013
Summary
Serotonin significantly regulates colonic motor function through its receptors and transporter. Altered serotonin levels contribute to conditions like irritable bowel syndrome, ulcerative colitis, and colostasis.
Area of Science:
- Gastroenterology
- Neurogastroenterology
- Pharmacology
Context:
- The gut-brain axis plays a crucial role in gastrointestinal motility.
- Serotonin (5-HT) is a key neurotransmitter involved in regulating various physiological processes, including colonic function.
- Understanding the serotoninergic system's influence on the colon is vital for addressing motility disorders.
Purpose:
- To review the role of the serotoninergic system in regulating colonic motor function.
- To elucidate the mechanisms by which serotonin and its related components influence colonic activity.
- To explore the implications of serotoninergic dysregulation in gastrointestinal diseases.
Summary:
- Serotonin (5-HT), its receptors (5-HT1, 5-HT2B, 5-HT3, 5-HT4), transporter, and metabolic enzymes are critical regulators of colonic motor function.
- Activation of specific serotonin receptors enhances colonic motor activity.
- Elevated serotonin levels increase colonic wall sensitivity, contributing to irritable bowel syndrome (IBS).
Impact:
- Serotonin is implicated in the pathogenesis of ulcerative colitis and colostasis.
- This review highlights serotonin's central role in colonic motility disorders.
- Findings provide insights for potential therapeutic strategies targeting the serotoninergic system in GI conditions.

01:23Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists
Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...
01:11Enteric 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.

01:28Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists
Prokinetic agents are specialized medications that stimulate gastrointestinal (GI) motility, promoting food movement through the GI tract. Dopamine, an inhibitory neurotransmitter, plays a significant role in this process, reducing GI motility and indirectly controlling the speed of digestion. Dopamine receptor antagonists, such as metoclopramide and domperidone, offer a unique advantage as prokinetic agents. By blocking the dopamine receptors, these drugs increase GI motility, improving food...
01:25Regulation of the Digestive System
Digestive activity regulation hinges on three primary components. Activation is prompted by a multitude of mechanical and chemical indicators, primarily detected by receptors within the stomach and intestines' walls. These receptors predominantly respond to factors such as mechanical stretching of the organ walls, changes in pH and osmolarity, and the presence of digesting materials and their by-products.

01:20Gastrointestinal Motility Disorders
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...
01:20Drugs Affecting GI Tract Motility: Other Laxatives
Laxatives are primarily used to alleviate constipation, a common gastrointestinal disorder characterized by infrequent bowel movements and difficulty passing stools. They work by various mechanisms to increase the volume or frequency of bowel movements. The primary modes of action of laxatives include increasing stool bulk, softening the stool, stimulating intestinal motility, and osmotically drawing water into the intestines.
