NettetThe 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, myelin does not form a single long sheath over the entire length of the axon.

Myelin acts as a form of insulation for axons, helping to send their signals over long distances. For this reason, myelin is mostly found in neurons that connect different brain regions, rather than in the neurons whose axons remain in the local region [2]. is saying no thanks rude

Nettet17. mai 2024 · The insulation for axons in the nervous system is provided by oligodendrocytes in the CNS and Schwann cells in the PNS. These cells use the same mechanism to insulate axon segments. Myelin is a lipid-rich sheath that surrounds the axon and by doing so creates a myelin sheath that facilitates the transmission of … NettetFor other uses, see Insulation (disambiguation). An insulator is a type of cis-regulatory element known as a long-range regulatory element. Found in multicellular eukaryotes … NettetThis insulation is important as the axon from a human motor neuron can be as long as a meter—from the base of the spine to the toes.

Myelin sheaths insulate the electrical activity of the axon to prevent electrical interference with the other nerve impulses in the closely packed neurone network of the central nervous system.

Nettet11. jun. 2010 · The thickness of the myelin sheath that insulates axons is fitted for optimal nerve conduction velocity. Here, we show that, in Schwann cells, mammalian disks large homolog 1 (Dlg1) interacts with PTEN (phosphatase and tensin homolog deleted on chromosome 10) to inhibit axonal stimulation of myelination.
