Structural organization of enteric nervous system in human colon.
The organization of the Enteric Nervous System (ENS) was studied in the human colon. Fragments of the whole colonic wall were either routinely processed or Zinc-Iodide Osmium impregnated. Single-layer preparations were also obtained from some of the Zinc-Iodide Osmium-impregnated specimens. The results showed some differences in the organization of human colonic ENS from that of other mammals. ...
متن کاملThe human enteric nervous system.
Decades of work in animal models have demonstrated that the enteric nervous system (ENS) plays a key role in controlling gut functions. Recent advances made it possible to extend such studies to the ENS of man in health and even in disease. Such studies have already provided new insights into the pathophysiology of inflammatory and possibly functional bowel diseases. Studies on human ENS reveal...
متن کاملThe enteric nervous system.
T HE enteric nervous system is a collection of neu-rons in the gastrointestinal tract 1 that constitutes the " brain of the gut " and can function independently of the central nervous system. 2 This system controls the motility, 3,4 exocrine and endocrine secretions, 5 and microcirculation 6 of the gastrointestinal tract; it is also involved in regulating immune and inflammatory processes. 7 In...
متن کاملDual purinergic synaptic transmission in the human enteric nervous system.
Based on findings in rodents, we sought to test the hypothesis that purinergic modulation of synaptic transmission occurs in the human intestine. Time series analysis of intraneuronal free Ca(2+) levels in submucosal plexus (SMP) from Roux-en-Y specimens was done using Zeiss LSM laser-scanning confocal fluo-4 AM Ca(2+) imaging. A 3-s fiber tract stimulation (FTS) was used to elicit a synaptic C...
متن کاملDevelopment of the enteric nervous system.
Development of the ENS requires the function of a diverse set of genes encoding transcription factors, signaling molecules, and their receptors. Mutations of these genes result in altered ENS function in animals and humans. In particular, such mutations have been shown to contribute to many cases of Hirschsprung's disease. Elucidation of the mechanisms of ENS development and function allow the ...
