Autonomic plexus

Autonomic Plexus

The autonomic plexus is a complex network of neurons that are part of the autonomic nervous system. These networks of neurons are responsible for the regulation of many involuntary body functions, including heart rate, digestion, respiratory rate, salivation, perspiration, pupillary dilation, micturition (urination), and sexual arousal.

Structure

The autonomic plexus is composed of both sympathetic and parasympathetic fibers. These fibers form a network of neurons that extend throughout the body, connecting various organs and systems. The autonomic plexus includes several specific plexuses, including the cardiac plexus, pulmonary plexus, and celiac plexus.

Function

The autonomic plexus plays a crucial role in the regulation of many involuntary body functions. It does this by transmitting signals from the brain and spinal cord to various organs and systems in the body. These signals can either stimulate or inhibit the activity of these organs and systems, depending on the specific function being regulated.

Clinical significance

Damage or disease affecting the autonomic plexus can lead to a variety of disorders, including autonomic neuropathy, orthostatic hypotension, and Horner's syndrome. Treatment for these conditions often involves managing the underlying cause of the damage or disease, as well as symptomatic treatment to manage the effects of the disorder.
