The insulation for axons in the nervous system is provided by glial cells, oligodendrocytes in the CNS, and Schwann cells in the PNS. Whereas the manner in which either cell is associated with the axon segment(s) that it insulates is different, the means of myelinating an axon segment is mostly the same in the two situations.

The neurotransmitters diffuse across the gap and then bind to chemical … NettetYes, the oligodendrocytes produce myelin sheaths in the CNS and Schwann cells produce myelin sheaths in the PNS. However, one other thing of note: a single oligodendrocyte can myelinate multiple neuronal axons, while a single Schwann cell can only myelinate a single nueron's axon.

Myelin 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 covering on an electrical wire, … NettetThe insulation for axons in the nervous system is provided by glial cells, oligodendrocytes in the CNS, and Schwann cells in the PNS.

Nettet16. jun. 2024 · Neurons are specialized cells that are capable of sending electrical as well as chemical signals. Most neurons contain dendrites, which receive these signals, and axons that send signals to other neurons or tissues.
