Detailed explanation-1: -The central nervous system is the brain and spinal cord, while the peripheral nervous system consists of everything else. The central nervous system’s responsibilities include receiving, processing, and responding to sensory information.
Detailed explanation-2: -The stimulus is modified, or transduced, into an electrical impulse in the receptor neuron. This incoming excitation, or afferent impulse, then passes along an extension, or axon, of the receptor to an adjustor, called an interneuron.
Detailed explanation-3: -Afferent or sensory neurons collect stimuli received by receptors throughout the body, including the skin, eyes, ears, nose, tongue as well as pain and other receptors in the internal organs. Sensory information is transmitted to the central nervous system, which includes the brain and spinal cord.
