Is axon the same as a nerve fiber?

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.

What do nerve fibers refer to?

An axon (from Greek ἄξων áxōn, axis), or nerve fiber (or nerve fibre: see spelling differences), is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body.

Is nerve A group of axon fibers?

A nerve consists of many structures including axons, glycocalyx, endoneurial fluid, endoneurium, perineurium, and epineurium. The axons are bundled together into groups called fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium.

What is the bundle of axons called in a nerve fiber?

fascicles
In the peripheral nervous system a bundle of axons is called a nerve. In the central nervous system a bundle of axons is called a tract. Each axon is surrounded by a delicate endoneurium layer. The course connective tissue layer called perineurium, binds the fibers into bundles called fascicles.

What is the difference between a neuron and an axon?

is that neuron is (cytology) a cell of the nervous system, which conducts nerve impulses; consisting of an axon and several dendrites neurons are connected by synapses while axon is (cytology) a nerve fibre which is a long slender projection of a nerve cell, and which conducts nerve impulses away from the body of the …

What is the function of the axon in a neuron?

Each neuron in your brain has one long cable that snakes away from the main part of the cell. This cable, several times thinner than a human hair, is called an axon, and it is where electrical impulses from the neuron travel away to be received by other neurons.

How does the axon help the nerve cell?

These branches split into smaller extensions known as axon terminal branches, or nerve terminals. Simply put, axons allow nerve cells to send electrical and chemical messages to other nerve, gland, and muscle cells using this internal communication process.
