The cell body directs all activities of the neuron. Dendrites extend out from the cell body and receive messages from other nerve cells. An axon is a long single fiber that transmits messages from the cell body to the dendrites of other neurons or to other body tissues, such as muscles.

A useful analogy is to think of a neuron as a tree. A neuron has three main parts: dendrites, an axon, and a cell body or soma (see image below), which can be represented as the branches, roots and trunk of a tree, respectively. A dendrite (tree branch) is where a neuron receives input from other cells.

Neurons have specialized projections called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body. Information from one neuron flows to another neuron across a synapse.

Interneurons

An axon, or nerve fiber, is a long slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron’s cell body or soma. Axons are in effect the primary transmission lines of the nervous system, and as bundles they help make up nerves.

Axon, also called nerve fibre, portion of a nerve cell (neuron) that carries nerve impulses away from the cell body. A neuron typically has one axon that connects it with other neurons or with muscle or gland cells.

Scientists do know that a severed axon will cause a neuron to quickly lose some of its incoming connections from other neurons. These connections occur at short, root-like tendrils called dendrites, which sprout from the neuron’s cell body, or soma.

Traumatic injury, interruption of blood supply, and degenerative diseases all can damage axons in peripheral nerves, or neuronal cell bodies and synapses in the more complex circuitry of the brain or spinal cord.

Central nervous system (CNS) axons do not spontaneously regenerate after injury in adult mammals. In contrast, peripheral nervous system (PNS) axons readily regenerate, allowing recovery of function after peripheral nerve damage.

A nerve injury can affect your brain’s ability to communicate with your muscles and organs. Damage to the peripheral nerves is called peripheral neuropathy. It’s important to get medical care for a peripheral nerve injury as soon as possible. Early diagnosis and treatment may prevent complications and permanent damage.

The signs of nerve damage Numbness or tingling in the hands and feet. Feeling like you’re wearing a tight glove or sock. Muscle weakness, especially in your arms or legs. Regularly dropping objects that you’re holding.

Foods That Fight Nerve Pain Common and useful sources of polyphenols include: Berries. Seasonal fruits. Darker leafy vegetables.
