Did you know?
Schwann cells are a variety of glial cells that keep peripheral nerve fibres (both myelinated and unmyelinated) alive. In myelinated axons, Schwann cells form the myelin sheath. The sheath is not continuous. Individual myelinating Schwann cells cover about 1 mm of an axon —equating to about 1000 Schwann cells along a 1-m length of the axon. The gaps between adjacent Schwann cells are called nodes of Ranvier. WebThese specialized Schwann cells have been shown to enhance synaptogenesis between cultured motor neurons from rodents and between motor neurons and target muscle in Xenopus. Perisynaptic Schwann cell processes make contact with the muscle first and the nerve terminal uses the processes as a guide to locate and innervate the muscle.
Web8 May 2024 · Schwann cells embryologically derive from the neural crest.

The plasma membrane of these Schwann cells spirals around the axons of neurons to form the fatty insulation that is required for faster transmission of electrical signals.
