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.

A nerve fibre, also called an axon, is a long and slender projection of nerve cells (or neurons) that carry electrical impulses away from the nerve cell body. A neuron typically has one nerve fibre emanating from its cell body that transmits impulses to other neurons, muscles or glands.

Jan 8, 2024 · Nerve fiber, also known as an axon, is a long, thin projection found on nerve cells (neurons) responsible for nerve impulses' conduction through the nerve cell body. Nerve fibers show properties including conductivity, velocity, refractive period, summation, and accommodation.

Oct 30, 2023 · By definition, nerves are bundles of axons (or nerve fibers) found in the PNS. Within the CNS, the axons form entities are known as tracts. While the structure of a nerve is simple, their functions, innervations and nomenclature can be complex.

Axons, cord-like groups of fibers in the center of your nerve. Dendrites, branches that carry electrical impulses. Endoneurium, a layer of connective tissue surrounding axons.

Nerve fibers can be classified based on different criteria: 1. Histologically, as myelinated or non-myelinated (Fig. 2.2). 2. Functionally, as afferent (sensory) or efferent (motor). 3. Based on diameter and conduction velocity which is known as Gasser and Erlanger’s classification.

Jan 24, 2025 · axon, portion of a nerve cell 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.

A nerve fiber is a threadlike extension of a nerve cell, consisting of an axon and myelin sheath, specialized to conduct electrical impulses away from the neuron body or receptor portion. AI generated definition based on: Nerves and Nerve Injuries, 2015
