  1. Supporting cells include Schwann cells and satellite cells in the PNS; in the CNS they include the various types of glial cells; oligodendrocytes, microglia, astrocytes, and ependymal cells. Schwann cells form a sheath of Schwann around axons of the PNS.

  2. Oct 30, 2023 · The Schwann cells, also known as neurolemmocytes, are a type of glial cells present exclusively in the peripheral nervous system. They develop from precursors in the neural crest and can be differentiated into two types of cells: Myelinating Schwann cells; Non-myelinating Schwann cells

  6. The myelin sheath terminates near the neuromuscular junction; at this point, three to five Schwann cells seamlessly continue wrapping the terminal nerve axon while extending into the knob-like space between the nerve and myofiber membrane. 1 Schwann cells function to store the neurotransmitter acetylcholine, clear cell debris, decode competing ...

  7. The Biology of Schwann Cells. Schwann cells are a diverse group of cells formed from neural crest cells. They are essential components of the peripheral nerves of both vertebrate and invertebrate nervous systems. The diversity of Schwann cell subsets and function is seen in those Schwann cells that form myelin – that uniquely specialised part ...

  8. The neuromuscular junction is an anatomic location in which signals are transmitted from a motor neuron to a muscle fiber via neurotransmitters (acetylcholine) which diffuse across a synapse. These signals cause muscle contraction. COMPONENTS.
