The axon which is also known as 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.

The function of the axon in a nerve cell is to carry the 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.

Here's how your nerves conduct the electrical signals.

Impulses that are sent along neurons are called action potentials.

An action potential (also known as an impulse) is the electrical current that travels the length of an axon when a neuron has been stimulated.

At rest the membrane inside of a neuron has a negative charge.

A nerve or nerves in the human body are like little electrical wires sending electricity from our bodies and electrical signals through our body to control our movements.

The nerves in the body are bundles of axons in the peripheral nervous system (PNS) that act as information highways to carry signals between the brain and spinal cord and the rest of the body.

Each axon is wrapped in a connective tissue sheath called the endoneurium.

Although there are trillions of nerves in the human body there are actually only 3 types of nerves.

The 3 types of nerves in the human body are.

1: Autonomic nerves. These nerves control the involuntary or partially voluntary activities of your body, including heart rate, blood pressure, digestion, and temperature regulation.

2: Motor nerves. These nerves control your movements and actions by passing information from your brain and spinal cord to your muscles.

 3: Sensory nerves. These nerves relay information from your skin and muscles back to your spinal cord and brain. The information is then processed to let you feel pain and other sensations.

The nerves in the body connect to your brain and through your spinal cord and then from there the nerves are spread out all over your body inside to connect to your fingers, arms, eyes, toes etc.

In the human body there are over 7 trillion nerves.

The nerves in the body are bundles of axons in the peripheral nervous system (PNS) that act as information highways to carry signals between the brain and spinal cord and the rest of the body.

Each axon is wrapped in a connective tissue sheath called the endoneurium.

In a way the nerves in our bodies are like electrical wires flowing the electricity through the wires but instead the nerves have signals and also electrical signals being sent through the nerves.

These nerves allow our brain to control our body and allow movement etc.

In the human body there are over 7 trillion nerves.

All these nerves are part of what’s known as your body’s nervous system.

You can think of nerves as your body’s electrical wiring as they transmit signals between your brain, spinal cord, and the rest of your body.

The nervous system consists of two components:

  • The central nervous system, which is made up of the brain, spinal cord, and nerves
  • The peripheral nervous system, which is made up of sensory neurons, clusters of neurons called ganglia, and other nerves that connect to one another as well as the rest of the central nervous system

These nerves and cells, called neurons, send messages throughout your body.

All nerves are important for proper day-to-day functioning, but there are two groups of nerves chiropractors focus on the most: cranial and spinal nerves.

Cranial nerves are located on the bottom surface of your brain.

There are 12 pairs of them, and they each have their own special function.

These cranial nerves connect your brain to different parts of your head, neck and trunk.

To prevent confusion (and because these nerves are located so close together), each pair is numbered with a Roman numeral, beginning at the front and moving to the back.

For example, the first nerve closest to the front of your head is the olfactory nerve, so its Roman numeral designation is I.

Most of the time, cranial nerves are classified as being either sensory or motor.

Sensory refers to your five senses — touch, smell, taste, hearing, and sight — and motor nerves are responsible for controlling the movement and function of glands or muscles.
