What are the 3 levels of the nervous system?
The human nervous system has inherited special functional capabilities from each stage of human evolutionary development. From this heritage, three major levels of the central nervous system have specific functional characteristics: (1) the spinal cord level, (2) the lower brain or subcortical level, and (3) the higher brain or cortical level.
How does the nervous system interact with the body?
The digestive system sends sensory information to the brain (CNS) The nervous system interacts with every system in your body. It is a specialized network of tissues, and neurons . The nervous system takes messages from the brain and tells what your body to do. Your body also sends messages back to your brain.
