Question

what is the correct order of steps in a reflex arc? stimulus, afferent/sensory signal, efferent/motor signal, muscle contraction muscle contraction, efferent/motor signal, afferent/ sensory signal efferent/motor signal, afferent/sensory signal, muscle contraction, stimulus afferent/sensory signal, stimulus, muscle contraction, efferent/motor signal

Explanation:

A reflex arc starts with a stimulus triggering sensory receptors. An afferent/sensory signal carries this information to the central nervous system. The CNS then sends an efferent/motor signal to the muscle, which results in muscle contraction as the response.

Answer:

Stimulus, afferent/sensory signal, efferent/motor signal, muscle contraction
