# Nervous System **Nervous System - right half of the brain controls the right half of the body. This means that only people in their right mind. (possibly incomplete)** **Central Nervous System** * Composed of the brain and spinal cord * Body's control center, coordinates body activities * Impulses travel through nerves in the brain to create your body's response. **Spinal Cord** (Description of spinal cord) **Peripheral Nervous System** * Composed of all nerves that carry messages to and from the central nervous system. * Peripheral and central nervous systems work together to make rapid changes in the body. **Brain** * **Three main sections** * **Cerebrum** * Hemispheres * Controls memory, intelligence, muscle control * **Cerebellum** * Controls balance, posture, and coordination * **Brainstem** * Controls involuntary activities (like breathing, heart rate) * **Divided into 4 lobes** * **Temporal lobe:** memory, emotion, hearing, language * **Frontal lobe:** decision-making, problem-solving, planning * **Parietal lobe:** processing of sensory information * **Occipital lobe:** vision
