MEDICAL PHYSIOLOGY

Detailed explanation-1: -The nervous system has three overlapping functions based on sensory input, integration, and motor output. At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body.

Detailed explanation-2: -A sensory neuron picks up stimuli from the internal or external environment and converts each stimulus into a nerve impulse. An interneuron is a neuron that carries nerve impulses from one neuron to another. A motor neuron sends an impulse to a muscle or gland, and the muscle or gland then reacts in response.
