1. Introduction to the Nervous System

2. Nervous System
Purpose: The Nervous System controls and coordinates functions throughout the body and responds to internal and external stimuli

3. Parts of the Nervous System
Central Nervous System:
Brain and Spinal Cord
Peripheral Nervous System: The rest of the nerves in the body

4. How do they work together?
Peripheral nerves connect the central nervous system to the rest of the body

5. Central Nervous System
Consists of the brain and spinal cord
Relays messages, processes and analyzes information

6. The Brain
Cerebrum - largest part of the brain. Thinking, language, motor function, touch
Cerebellum - “little brain”. Controls coordination, balance, movement.
Thalamus - located just above brain stem. Motor function,
sensory perception
Hypothalamus - size of pearl. Controls autonomic and endocrine function, food and water intake

7. Peripheral Nervous System
Consists of all of the nerves that are not a part of the brain or spinal cord
Includes sensory and motor nerves

8. Peripheral Nervous System
Somatic Nervous Sys:
Controls voluntary movement of skeletal muscle
Autonomic Nervous Sys:
Controls involuntary movement such as respiration and heart beat
