What are the 3 main functions of the nervous system *?

Sensation, integration, and response are the first three fundamental functions of the nervous system. The second distinction is between somatic and autonomic control of the body, which is largely determined by the structures involved in the response.

What are the 3 main roles of the nervous system?

Based on sensory input, integration, and motor output, the nervous system performs three interrelated but independent tasks. At a more integrative level, the nervous system’s main job is to regulate and transmit information throughout the body.

What are the brain functions?

What does a brain do? The brain is a sophisticated organ that manages every bodily function as well as thought, memory, emotion, touch, motor skills, vision, breathing, temperature, and hunger. The central nervous system, or CNS, is made up of the spinal cord that emerges from the brain.
