what is reflex arc?

Asked by  | 13th Dec, 2009, 10:50: AM

Expert Answer:

The essential neural pathway involved in a reflex action, which links the stimulus, the activated sensory receptor, and the response. A motor reflex arc usually consists of five elements; receptor, sensory neurone, an integration centre (e.g. an association neurone in the central nervous system; this may be absent in some reflex arcs), a motor neurone, and a muscle that acts as the effector.
