Question

Quizplus · Accepted Answer

A reflex arc involves a sensory neuron carrying impulses to the CNS, with interneurons often present in the CNS to process the signal before it travels to a motor neuron. The stimulus for the reflex is detected by a receptor, and the effector is often muscle tissue that is activated by impulses from a motor neuron. Synapses in the reflex arc are not typically found in the dorsal root ganglia.
