The Central Nervous System The Central Nervous System processes all of the body’s information. The two parts of the central nervous system are the brain and the spinal cord.
The Peripheral Nervous System The Peripheral Nervous System includes all of the other nerves in the body The Peripheral Nervous System is divided into two categories: – The Somatic Nervous System – The Autonomic Nervous System
The Somatic Nervous System The Somatic Nervous System connects the brain to the muscles of the body. It controls all of our voluntary muscle movements. It is connected to the motor cortex in the brain.
The Autonomic Nervous System This system is also responsible for actions associated with stress and perceived threats. The autonomic system is further broken down into two systems: – Sympathetic Nervous System – Parasympathetic Nervous System
The Sympathetic Nervous System The Sympathetic Nervous System mobilizes the body to respond to stress. It is our alert system. – Accelerates the heart, blood pressure, respiration), released adrenaline… – Conserves energy for fight by slowing down digestion, etc.
The Parasympathetic Nervous System The Parasympathetic Nervous System returns the body to a normal state after a stressful encounter.

I. The Forebrain There are five main regions of the forebrain to study: – The Cerebral Cortex – Thalamus – Hypothalamus – Amygdala – Hippocampus
The CEREBRAL CORTEX is the intricate, wrinkled covering of the brain (FISSURES) In addition to interneurons, it contains GLIAL CELLS, which guide neural connections, provide nutrients to myelin, and mop up neurotransmitters
