Auerbach’s Plexus: From 1 Different Sources

(myenteric plexus) a collection of nerve fibres – fine branches of the *vagus nerve – within the walls of the intestine. It supplies the muscle layers and controls the movements of *peristalsis. [L. Auerbach (1828–97), German anatomist]

Choroid Plexus

An extensive web of blood vessels occurring in the ventricles of the BRAIN and producing the CEREBROSPINAL FLUID.... choroid plexus

Plexus

A network of nerves or vessels: for example, the brachial and sacral plexuses of nerves and the choroid plexus of veins within the brain.... plexus

Solar Plexus

A large network of sympathetic nerves and ganglia situated in the abdomen behind the stomach, where it surrounds the coeliac artery. Branches of the VAGUS nerve – the most important part of the PARASYMPATHETIC NERVOUS SYSTEM – lead into the solar plexus, which in turn distributes branches to the stomach, intestines and several other abdominal organs. A severe blow in the solar plexus may cause temporary unconsciousness.... solar plexus

Brachial Plexus

A collection of large nerve trunks that are formed from nerve roots of the lower part of the cervical spine (in the neck) and the upper part of the thoracic spine (in the chest). These nerve trunks divide into the musculocutaneous, axillary, median, ulnar, and radial nerves, which control muscles in and receive sensation from the arm and hand. Injuries to this plexus can cause loss of movement and sensation in the arm.

In severe injuries, there may be damage to both the upper and the lower nerve roots of the brachial plexus, producing complete paralysis of the arm.

Paralysis may be temporary if the stretching was not severe enough to tear nerve fibres.

Nerve roots that have been torn can be repaired by nerve grafting, a microsurgery procedure.

If a nerve root has become separated from the spinal cord, surgical repair will not be successful.

Apart from injuries, the brachial plexus may be compressed by the presence of a cervical rib (extra rib).... brachial plexus

Myenteric Plexus

Broadly, the several neuron masses, ganglia, and nerve fiber plexus that lie in the walls of the intestinal tract, particularly the small intestine. They monitor and stimulate local muscle and glandular functions as well as blood supply, with little interface or control by the central nervous system or the autonomics. Each synapse away from the CNS gives greater autonomy, and these nerves only listen to God ... and food. This means the small intestine is relatively free of stress syndromes.... myenteric plexus

Kiesselbach’s Plexus

a collection of capillaries in the mucosa at the anterior part of the nasal septum. Nosebleeds frequently have their origin from this plexus. See epistaxis; Little’s area. [W. Kiesselbach (1839–1902), German laryngologist]... kiesselbach’s plexus

Meissner’s Plexus

(submucous plexus) a fine network of parasympathetic nerve fibres in the wall of the alimentary canal, supplying the muscles and mucous membrane. [G. Meissner (1829–1905), German physiologist]... meissner’s plexus
