myelinated axons can deliver the nervous system impulse quickly from cell to cell because the myelin itself as well as the solution in which nerve cells are suspended are highly effective conducting materials. Additionally, by encasing the axon much like the wire enclosed in an electrical cord,...

WHAT ARE NERVES? STRUCTURE OF NERVES CONNECTIVE TISSUE THREE TYPES OF NERVES Sensory Nerves Motor Nerves Autonomic Nerves TYPES OF CRANIAL NERVES Cranial Nerve I – Olfactory Nerve Cranial Nerve II – Optic Nerve Cranial Nerves III, IV, and VI – Oculomotor Nerve, Trochlear Nerve, and Abducens...
One theory derived from observing the eggs of chickens and frogs suggests that axons grow according to a spatial topography. The relative dispersal of chemical cues from the multitude of nearby nerve cells acts as a kind of magnetic alignment to organize the axon’s growth direction. Another ...

Something goes wrong in some part of the nerve. Perhaps it's in the myelin, the membranous lining of nerve cells in which axons float. Or it could be in the axons, which are connectors responsible for transferring the electrical impulses from one cellular body to the next. Even the nerve...
nerve originates in the olfactory epithelium (a collection of cells that line the nasal cavity in humans). The epithelium contains millions of olfactory receptors. Bundles of the axons of these receptors are called fila olfactoria; these bundles are collectively known as the olfactory nerve. ...
Nerve is a bundle of neuronal axons outside the central nervous system, transmitting signals to and from the body and brain, while tract is a collection of axons within the central nervous system, facilitating communication between different brain areas. ...
What is the thickest nerve in the body? Nerves: Nerves are peripheral nervous system organs that resemble cords. Although they vary in size, nerves are basically bundles of axons that extend from the central nervous system toward the peripheral structures of the body. ...
