|January 24, 1980
Resumen
El sistema nervioso entérico (ENS) tiene dos plexos principales. Este estudio encontró que las fibras nerviosas conectan estos plexos, lo que sugiere que coordinan la función intestinal.
Área de la Ciencia:
- La neurociencia es la neurociencia.
- Gastroenterología y Gastroenterología.
- Biología celular Biología celular.
Sus antecedentes:
- El sistema nervioso entérico (ENS) del intestino de los mamíferos comprende el plexo mientero y el plexo submucoso.
- Comprender las conexiones entre estos plexos es crucial para la función del SNE.
- El conocimiento actual de las relaciones anatómicas y funcionales entre el plexo es limitado.
Objetivo del estudio:
- Investigar las conexiones anatómicas y funcionales entre los plexos mientérico y submucoso.
- Para aclarar la relación entre los dos principales plexos del SNE.
- Explorar el papel de los neurotransmisores en la comunicación entre el plexo.
Principales métodos:
- Se utilizaron métodos in vitro establecidos para mantener los plexos mientero y submucoso por separado.
- Realizó estudios inmunohistoquímicos en plexos aislados y secciones de la pared intestinal.
- Realizó radioinmunoensayos en extractos de tejidos.
Principales resultados:
- Proyecciones recíprocas identificadas entre los plexos mientérico y submucoso a través de las fibras nerviosas.
- Se detectó la presencia de polipéptido intestinal vasoactivo (VIP) y sustancia P en estas fibras nerviosas proyectadas.
- Los resultados del radioinmunoensayo apoyaron los hallazgos inmunohistoquímicos.
Conclusiones:
- Pruebas demostradas de conexiones directas de fibras nerviosas entre los plexos mientéricos y submucosos.
- Sugiere que la VIP y la sustancia P juegan un papel en la coordinación de las funciones de los dos plexos entéricos.
- Proporciona nuevos conocimientos sobre la organización estructural y funcional del SNE.

Autonomic Nervous System: Overview
The human nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is composed of the brain and spinal cord, while the PNS contains nerve cells, clusters of nerve cells, and the sensory receptors that are outside the CNS. The PNS has two types of nerve cells: sensory (afferent) and motor (efferent). Sensory cells send signals to the CNS from receptors, and motor cells carry signals from the CNS to organs, muscles, and...
Peripheral Nervous System: Ganglia and Nerves
The Peripheral Nervous System (PNS) is a crucial component of the body's neural network, extending beyond the central nervous system (CNS) to bridge the gap between the CNS and the external environment. It encompasses nerves, ganglia, and sensory receptors.
Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...

Sympathetic Pathways: Sympathetic Chain Ganglia
The sympathetic chain ganglia, also known as the sympathetic trunk ganglia or paravertebral ganglia, are a series of ganglia located bilaterally on either side of the spinal column. These ganglia serve as relay stations for the sympathetic nervous system. Preganglionic neurons originating in the spinal cord project their axons to the sympathetic chain ganglia. Within the ganglia, these preganglionic fibers synapse with postganglionic neurons.The postganglionic neurons of the sympathetic trunk...
Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
The sympathetic pathways of the collateral ganglia and adrenal medulla serve unique but interconnected roles in the sympathetic response.
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...

Cranial Part of Parasympathetic Division
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.
The vagus nerve (cranial nerve X) alone accounts for approximately 75...

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...
