The esophageal plexus is formed by nerve fibers from two sources: 1.branches of the vagus nerve 2.visceral branches of the sympathetic trunk. The esophageal plexus and the cardiac plexus contain the same types of fibers and are both considered thoracic autonomic plexus(es).

Parasympathetic Fibers

1. The Vagus nerve delivers two fiber types to the esophageal plexus:

A. Preganglionic Parasympathetic fibers (Preganglionic fibers) - These fibers have their cell bodies located in the dorsal motor nucleus of the vagus and they will synapse on the terminal ganglia in the walls of the esophagus.
B. Afferent fibers- These fibers are primarily concerned with autonomic reflexes and they have their cell bodies in the inferior ganglion of the vagus.

"Note": These vagal fibers in the esophageal plexus reform to make the anterior vagal trunk (left vagus) and the posterior vagal trunk (right vagus). Anterior and posterior being terms in relation to the esophagus. a mnemonic for which is 'LARP': Left becomes Anterior, Right becomes Posterior.

Sympathetic Fibers

2. The visceral branches of the sympathetic trunk also deliver two fiber types to the esophageal plexus

A. sympathetic postganglionic fibers- The cell bodies of these fibers are located in the sympathetic chain ganglia. The cell bodies of the preganglionic fibers, the first neuron of this two neuron chain, are located in the intermediolateral cell column (IMLCC) of the thoracic spinal cord.
B. Afferent fibers- These fibers are primarily concerned with pain and have cell bodies located in the dorsal root ganglion.

The lower esophageal sphincter (LES) is a specialized, thickened muscle region with a high resting tone mediated by myogenic and neurogenic mechanisms. During swallowing or belching, the LES undergoes strong inhibitory innervation. In the horse, the LES seems to be organized as a "one-way" structure

BACKGROUND: Esophageal elongation by traction suture is used in pediatric patients to manage long-gap esophageal atresia (EA). There was no histological evidence of the esophageal elongation. Here, we sought to clarify the histologic effects of traction on the esophagus by using a rat EA model simul
