Axon - Wikipedia
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. The function of the axon is to transmit information to different ...
Nerve: anatomy, definition, types, functions - Kenhub
2023年10月30日 · Some nerve fibers (axons) and are enveloped in myelin sheath, a lipid and protein rich layer that aids in increasing the velocity of electrical impulse conduction. Those fibers are called myelinated fibers whereas the fibers without a myelin sheath are unmyelinated.

Nerve Fiber Types - ScienceDirect
2015年1月1日 · A nerve fiber is a long process of nerve cell (neurone) called the axon. The nerve cell’s body is anatomically situated in the central nervous system or within the ganglia of the peripheral nervous system.
Parts of a neuron: Structure and functions | Kenhub
2023年12月21日 · The axon of a neuron is also known as a nerve fiber. The membrane of an axon is known as the axolemma, while the cytoplasm is also referred to as axoplasm. Bundles of axons in the CNS form a tract, while in the PNS, they are referred to as fascicles (which, when bound together with connective tissue, form nerves).
Nerve Fiber - an overview | ScienceDirect Topics
A nerve fiber is a threadlike extension of a nerve cell (the neuron) and consists of an axon and myelin sheath (if present). A neuron is formed by its perikaryon or the cell body and cytoplasmic processes.
Axon | Neurons, Nerve Fibers & Signaling | Britannica
Axon, 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. Some axons may be quite long, reaching, for example, from the spinal cord down to a toe.

2023年5月1日 · Nerve fibers that send information from sensory neurons to the central nervous system are termed afferent nerve fibers, while nerve fibers that carry information away from the central nervous system, such as the motor neurons to …
Understanding the Structure and Function of an Axon - Verywell …
2024年2月14日 · An axon is a thin fiber that connects neurons (nerve cells) to that they can communicate. Neurons communicate via electrical impulses that trigger the release of "chemical messengers" called neurotransmitters. Axons also transmit electrical impulses from muscle and gland cells to the brain.
