Document Summary

Cranial: nerves go from your brain to your eyes, mouth, ears, and other parts of your head. Central: nerves are in your brain and spinal cord. Peripheral: nerves go from your spinal cord to your arms, hands, legs, and feet. Autonomic: nerves go from your spinal cord to your lungs, heart, stomach, intestines, bladders, and sex organs. Brain & spinal cord share a common space. Gets absorbed into the blood in subarachnoid space. Cns is also wrapped in a bony covering. Cns can be conceptualized as an input-output system. Nervous system can be conceptualized as an input-output system. Receives afferent input from the body and internal organs. Generates a pattern of neural activity to have an effect. Frontal lobe (front), parietal lobe (back), occipital lobe (back side), temporal lobe (front side), cingulate gyrus (in the center) Diencephalon: sensory relay station in the brain. Receives most types of sensory input then relays this input to cortical regions.
