Branchlike structures on one end of a neuron responsible for taking information away from the cell body.
The fiber-like extension of a neuron through which the cell sends information to target cells.
The long-nerve cell process that conducts impulses from the cell body.
A nerve fiber that carries nerve impulses away from the cell body of a neuron.
Nerve cell process that carries the impulse away from the cell body to the site of action or response, the effector (e.g., muscle); some axons have a myelin sheath (compare dendrite).
Structural process of a nerve cell that conducts nervous impulses away from the cell body and dendrites.
A nerve fiber: a single process extending from the cell body of a neuron and carrying nerve impulses away from it. An axon may be over a meter in length in certain neurons. In large nerves the axon has a sheath (neurilemma) made of myelin; this is interrupted at intervals by gaps called nodes of Ranvier, at which branches of the axon leave. An axon ends by dividing into several branches called telodendria, which make contact with other nerves or with muscle or gland membranes.
An elongated projection of a nerve cell or neurone that carries an electrical impulse to the tissue at the end of the axon. Large axons are covered by a sheath of insulating myelin which is interrupted at intervals by nodes of Lanvier, where other axons branch out. An axon may be more than a metre long. It ends by branching into several filaments called telodendria, and these are in contact with muscle or gland membranes and other nerves.
A process of a neuron that conducts impulses away from the cell body. Typically, it arises from a portion of the cell devoid of Nissl granules, the axon hillock. Axons may possess either or both of two sheaths (myelin sheath and neurilemma) or neither. Axons are usually long and straight, and most end in synapses in the central nervous system or ganglia or in effector organs (e.g., motor neurons). They may give off side branches or collaterals. An axon with its sheath(s) constitutes a nerve fiber.
The extension of a neuron through which impulses are sent away from the body to other neurons, glands, or muscles.
The extension or prolongation of a nerve cell (neuron) that conducts impulses to other nerve cells or muscles. Axons are generally smaller than 1 micron (1 micron = 1/1,000,000 of a meter) in diameter, but can be as much as a half meter in length.
A long, thin fiber of a neuron that carries impulses away from the cell body.
The elongated projection of a nerve fiber that typically carries nerve impulses away from the cell body of a neuron.
The axon, a slender and elongated portion of a neuron (nerve cell), serves as a pathway for transmitting nerve impulses. It plays a vital role in facilitating communication within the nervous system. Many axons in the body are enveloped by a protective coating called the myelin sheath, which is composed of fatty substances. This myelin sheath aids in insulating the axon and enhances the efficiency of nerve signal conduction.
A fiber that transmits signals, extending from and serving as an extension of a nerve cell.
