Neurones as rapid communication cells

Annotated pathway from receptor to effector with an enlarged myelinated motor neurone labelled with dendrites, cell body, axon, Schwann cell, nodes of Ranvier and axon terminals

Neurones are specialised cells that carry information between receptors, the central nervous system and effectors. A common pathway is receptor to sensory neurone to relay neurone to motor neurone to effector.
