WebMay 17, 2024 · Describe the process of myelination and axon regeneration. Nervous tissue is composed of two types of cells: neurons and glia, as shown in Figure 11.3. 1. Neurons … WebActually, these cells have 2 axons rather than an axon and dendrite. One axon extends centrally toward the spinal cord, the other axon extends toward the skin or muscle. Multipolar neurons have many processes that extend from the cell body. However, each neuron has only one axon (examples: spinal motor neurons, pyramidal neurons, …

Did you know?
WebThe axon carries the action potential to the next neuron. Neurons usually have one or two axons. Some axons are covered with myelin, which acts as an insulator to minimize dissipation of the electrical signal as it travels … WebAboutTranscript. Neurons (or nerve cells) are specialized cells that transmit and receive electrical signals in the body. Neurons are composed of three main parts: dendrites, a cell body, and an axon. Signals are received through the dendrites, travel to the cell body, and continue down the axon until they reach the synapse (the communication ...
WebMyelin is a lipid-rich material that surrounds nerve cell axons (the nervous system's "wires") to insulate them and increase the rate at which electrical impulses (called action potentials) are passed along the axon. The myelinated axon can be likened to an electrical wire (the axon) with insulating material (myelin) around it. However, unlike the plastic … WebAt its far end, the axon splits up into many axon terminal. Each forms a synapse with a dendrite or cell body of another neuron. The cell to which the axon terminal belongs (sending cell) is called the presynaptic cell, …
