Did you know?
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 neurons, muscles, and glands. In certain sensory neurons (pseudounipolar neurons), such as those for touch and warmth, the axons are called afferent ner… WebMar 1, 2003 · That damage to axons in plaques is responsible for axon loss in normal‐appearing white matter is supported by the finding that axon density in the corpus callosum strongly correlates with the volume of plaques in the cerebral hemispheres (Evangelou et al., 2000b).

WebThe axon is like the tree’s long trunk. The nutrients are transported from the tree’s roots up through the tree’s trunk. Similarly, the axon transports the impulses from the soma onward along its path. The axon terminal is like the tree buds at the end of the tree’s branches. Leaves and pollen come out of these buds.
