WebMyelin produced by either oligodendrocytes (CNS) or Schwann cells (PNS) extends from the glial plasma membrane and spirally enwraps axonal segments. The myelinated axonal segments are also known as internodes, whereas the unmyelinated axonal segments are called the nodes of Ranvier ( figure 2A ). Web[00108] Myelin: A lipid substance forming a sheath (known as the myelin sheath) around the axons of certain nerve fibers. Myelin is an electrical insulator that serves to speed the conduction of nerve impulses in nerve fibers.

Web11 okt. 2024 · Axons are a key component of a neuron, they conduct electrical signals in the form of an action potential from the cell body of the neuron to its axon terminal where it synapses with another neuron. An axon is insulated by a myelin sheath throughout its length to increase the velocity of these electrical signals allowing signals to propagate … WebOligodendrocytes and Schwann cells. The major function of oligodendrocytes and Schwann cells is the formation of myelin. Myelin acts as an insulator of axonal segments and is a prerequisite for the high velocity of nerve conduction, of up to 200 m/second. The association of glial cells with axons is also found in invertebrates.
