NODE uv RON-vee-ay A short region of exposed axon between Schwann cells on neurons of the vertebrate peripheral nervous system. 614
(rahn'-vee-A) A gap in the myelin sheath covering a nerve fiber, which accelerates the rate of impulse conduction.
Local area of unmyelinated axon that occurs at intervals along a myelinated axon.
A constriction of mylelinated nerve fibers at regular intervals at which the myelin sheath is absent and the axon is enclosed only by sheath cell processes; also known as a neurofibril node.
A gap between two of the Schwann cells that make up an axon's myelin sheath; serves as a point for generating a nerve impulse.
Short unmyelinated segment of an axon.
The gap in the myelin sheath where the action potential occurs during saltatory conduction.
a space, along a myelinated nerve fiber, between the adjacent neurolemmocytes (Schwann cells) that form the myelin sheath and the neurolemma; also called neurofibral node
Area between two Schwann cells which is not covered by myelin
