Anatomy of a nerve: A nerve consists of several nerve fibers (axons). Each individual fiber is covered in a layer called the endoneurium, which is composed of loose connective tissue. A bundle of fibers is referred to as fascicles. These fascicles are encased in a several layers called the perineurium. Surrounding the bundles of fascicles, is another layer called the epineurium, which consists of dense irregular tissue.

Nerve fibers of the peripheral nervous system are myelinated, consisting of Schwann cells. Each fiber is surrounded by the endoneurium consisting of loose connective tissue. The fibers are gathered in bundles called fascicles and each fascicle is wrapped in the perineurium. The perineurium is composed of overlapping epithelium-like cells. Several fascicles also bundle together and wrapped in the epineurium which consist of dense irregular tissue and protects the nerve from stretching and…

The neuromuscular junction is a synapse between a nerve fiber and a muscle fiber. Just one nerve fiber is able to stimulate several points within the neuromuscular junction. The structure also depicted shows the synaptic knob and synaptic cleft. The knob is the site of synaptic vesicles and where neurotransmitters are released, the cleft is the space where these neurotransmitters diffuse through.

There are multiple classifications of Nerve Fibers including: Afferent fibers: Carry sensory signals from receipts to the CNS Efferent fibers: Carry motor signals from he CNS to effectors Somatic fibers: Innervate skin, skeletal muscles, bones, and joints Visceral fibers: Innervate blood vessels, glands, and viscera General fibers: Innervate widespread organs Special fibers: Innervate more localized organs in the head, including the eyes, ears, olfactory, etc.

The Auerbach Plexus, also known as the Myenteric plexus, is a collection of nerve fibers within the walls of the intestine that supplies the muscle layers and controls the movements of peristalsis. This structure is named after Auerbach Leopold. In 1862 he published his description of a plexus of autonomic nerve fibers in the intestines of vertebrates. Shortly afterward he presented his description of the ganglion cells situated in the plexus.
