AP PSYCHOLOGY

Detailed explanation-1: -The correct sequence of the components in a reflex arc is given below: Receptors → Sensory neuron → Spinal cord → Motor neuron → Muscle.

Detailed explanation-2: -Interneuron is the neuron that connects the sensory neuron and the motor neuron. They are present in the central nervous system. It collects sensory impulses and processess them to generates quick responses.

Detailed explanation-3: -The primary components of the reflex arc are the sensory neurons (or receptors) that receive stimulation and in turn connect to other nerve cells that activate muscle cells (or effectors), which perform the reflex action.

Detailed explanation-4: -Afferent neurons in the dorsal roots carry impulses from the body’s sensory receptors to the spinal cord, where the information begins to be processed.

Detailed explanation-5: -Receptors→sensory neuron→spinal cord→motor neuron→muscles. The path taken by nerve impulse in a reflex action is called a reflex arc.
