THE NERVOUS SYSTEM

Purpose of the Nervous System Communication and control

Nervous system’s important parts Brain –Controls actions, thought and holds memories

Nervous system’s important parts Spinal Cord –Relays information between brain and body

Nervous system’s important parts Nerves –Sends messages to brain and gets messages from brain

Nervous system’s important parts Neurons –Nerve cells that carry information

Video #2 – Neurons and Nerve cells

Problems with the Nervous System Head Injury – Brain damage Spinal Injury – causes paralysis Addiction – mental or physical need for a drug or other substance

Keeping the system healthy Do not abuse drugs Use protective gear THINK before taking a risk Get enough sleep (8 or more hours)
