What is the function of the Myenteric Plexus? The Myenteric plexus is an arrangement of nerve fibers and neuron cells that are situated within the muscular tissue layer. This layer encloses the esophagus, stomach, and intestines. Myenteric Plexus is also known as ‘Auerbach's plexus’.

Trigeminal Nerve (Cranial Nerve V) The trigeminal nerve sensory and motor roots exit the brainstem from the ventrolateral pons. It then enters Meckel's cave located posterior and inferolateral to the cavernous sinus, and here the trigeminal (gasserian or semillunar) ganglion is formed and gives off the three major branches.

A and Pi Chapter 15 Identify the areas supply by the individual nerves emerging from the cervical plexus. Muscles and skin of the neck, upper shoulders, and parts of the head are supply by nerves emerging from the cervical plexus. The phrenic nerve also exits at this plexus, and it innervates the diaphragm.

GI The Enteric Plexus. The portion of the nervous system that is only contained within, and only affects, the functions of the GI tract, including the motor and secretory functions. The enteric plexus therefore has both Sympathetic and Parasympathetic functions.

What is the function of the Myenteric Plexus? Basically, Myenteric plexus is a system of nerves that are flanked by the circular and longitudinal layers of the muscular digestive tract. Myenteric Plexus is a segment of the enteric nervous system.

The Cervical Plexus After arising from the cervical plexus, the nerve travels down the surface of the anterior scalene muscle, and enters the thorax. In the thoracic cavity, the nerve descends anteriorly to the root of the lung to reach the diaphragm. A good memory aid for the roots of the phrenic nerve is C3,4,5 keeps the diaphragm alive.ensory Branches. The cutaneous branches of the cervical plexus supply the skin of the neck, upper thorax, scalp and ear. These nerves all enter the skin at the middle of the posterior border of the sternocleidomastoid.

Earthworm Sympathetic nervous system. The sympathetic nervous system consists of nerve plexuses in the epidermis and alimentary canal. (A plexus is a web of nerve cells connected together in a two dimensional grid.) The nerves that run along the body wall pass between the outer circular and inner longitudinal muscle layers of the wall.

- Pleural innervation: It's true that the visceral layer of pleura has no sensory innervation. But the other layer of pleura -- the parietal pleura -- is continuous with the visceral one and lines the inside of the chest.This parietal pleura is richly innervated via intercostal and phrenic nerves, and is very painful when injured or inflamed. Ask anyone who's been awake while receiving a chest tube.leural innervation: It's true that the visceral layer of pleura has no sensory innervation.

The Cervical Plexus The cervical plexus is a network of nerve fibres that supplies innervation to some of the structures in the neck and trunk. It is located in the posterior triangle of the neck, halfway up the sternocleidomastoid muscle, and within the prevertebral layer of cervical fascia.he muscular branches of the cervical plexus are located deep to the sensory branches. They supply some of the muscles of the neck, back and the diaphragm. After arising from the cervical plexus, the muscular branches tend to travel initially in an anteromedial direction.

Vasomotor Sympathetic nerve fibers travel around the tunica media of the artery, secrete neurotransmitters such as norepinephrine into the extracellular fluid surrounding the smooth muscle (tunica media) from the terminal knob of the axon.

Oral: Four layers of the G.I. tract Muscularis propria (externa): smooth muscle layer. There are usually two layers; the inner layer is circular, and the outer layer is longitudinal. These layers of smooth muscle are used for peristalsis (rhythmic waves of contraction), to move food down through the gut.

The Enteric Nervous System 1 The myenteric plexus is located between the longitudinal and circular layers of muscle in the tunica muscularis and, appropriately, exerts control primarily over digestive tract motility.  The submucous plexus, as its name implies, is buried in the submucosa.

- The muscularis mucosa allows for movement of the mucosa independent of the wall of the digestive tract, thereby increasing its contact with food. In most of the alimentary canal, the muscularis mucosa consists of an inner circular and outer longitudinal layer of smooth muscle.The Submucosa: The submucosa consists of moderately dense irregular connective tissue. It contains blood and lymph vessels and nerve plexi.n most of the digestive tract, the muscularis externa consists of an inner circular and outer longitudinal layer of smooth muscle. The inner circular layer is arranged in a tight spiral, and its contraction results in the mixing of food by constricting the lumen of the tube.

Neuroscience For Kids The enteric nervous system is a third division of the autonomic nervous system that you do not hear much about. The enteric nervous system is a meshwork of nerve fibers that innervate the viscera (gastrointestinal tract, pancreas, and gall bladder).

Parasympathetic nervous system As the main vagus nerves continue into the thorax they become intimately linked with the esophagus and sympathetic nerves from the sympathetic trunks to form the esophageal plexus. This is very efficient as the major function of the vagus nerve from there on will be control of the gut smooth muscles and glands.

The Enteric Nervous System In addition to the two major enteric nerve plexuses, there are minor plexuses beneath the serosa, within the circular smooth muscle and in the mucosa. Within enteric plexuses are three types of neurons, most of which are multipolar: 1  Sensory neurons receive information from sensory receptors in the mucosa and muscle.

- The esophagus conveys food from the pharynx to the stomach by means of peristaltic waves which begin as a result of the swallowing reflex. The inner wall of the esophagus is lined with stratified squamous epithelium. It shows up as large purple on your slide.Notice that the cells at the base of this epithelial layer are cuboidal.emember that the epithelial layer, the connective tissue and the muscularis mucosa comprise the mucosa. The submucosa is the next layer toward the outside and contains the submucosal glands. These large purple-staining glands produce mucus which lubricates the esophagus.
