Sep 23, 2024 · Axons are grouped based on their myelination and function. Group A and B nerve fibers are myelinated, meaning they are covered by a fatty sheath that increases the speed of impulse transmission. Group C nerve fibers are unmyelinated and transmit signals more slowly.
Oct 30, 2023 · Learn about the morphology and histology of neurons, the basic building blocks of the nervous system. Axons are processes from the cell body (soma) or from the axon hillock (a specialized part of the cell body) of a neuron that conduct impulses away from cell body.

An axon (from Greek ἄξων áxōn, axis) or nerve fiber (or nervefibre: 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.
Nov 14, 2022 · Axon connects to the soma at a cone-like part of the structure known as the axon hillock. This part of the axon has considerable functional importance since action potential originates here. In other words, this region of the neurolemma processes the incoming signals from other neurons.

Dec 21, 2023 · Conductive part (axon), which conducts electrical impulses away from the cell body. Transmissive part (axon terminals), where axons communicate with other neurons or effectors (target structures which respond to nerve impulses) Neurons are categorized into different types based on their unique morphologies and functions.

Apr 1, 2011 · Four major functions of the axon are illustrated (i.e., spike initiation, spike propagation, excitation-release coupling, and integration). A spike initiates in the axon initial segment (AIS) and propagates towards the terminal where the neurotransmitter is released.

May 25, 1995 · The axon, which is interposed between the cell body and the synaptic terminals in most neurons, plays a crucial role in connecting neurons and acting as a conduit for the transmission of information between them.
