The Nervous System

When you react to catch a dropped ruler your body reacts in this order:

• 1) muscles contract 2) eyes sense ruler move 3) message sent to brain 4) message sent to the muscles
• 1) message sent to muscles 2) muscles contract 3) message sent to brain 4) eyes sense ruler move
• 1) eyes contract 2) muscles sent to brain 3) message sense moves 4) ruler is sent to muscles
• 1) eyes sense ruler move 2) message sent to brain 3) message sent to muscles 4) muscles contract

This part of the brain, sometimes called the 'mini-brain,' controls balance and body position?

• right hemisphere
• medulla oblongata
• cerebellum
• left hemisphere

Which part of the neuron is a long fiber that sends information to other cells?

• body of the neuron
• axon
• dendrite
• spinal cord

Neurons that send information from the brain TO THE MUSCLES.

• sensory neurons
• arteries
• veins
• motor neurons

Neurons that send information from the environment TO THE BRAIN.

• sensory neurons
• arteries
• veins
• motor neurons

Which part of the brain controls vital automatic functions such as breathing and heart rate?

• cortex
• brain stem
• cerebellum
• hypothalmus

What is NOT true about a REFLEX?

• It is a QUICK, automatic response to a stimulus.
• They are mostly controlled by the spinal cord.
• An example is blinking.
• They are controlled by the heart.

The right side of the body is controlled by

• RIGHT hemisphere of the brain
• LEFT hemisphere of the brain
• amygdala
• toes

Nerve cells that send information from one to another are called:

• spinal cells
• neurons
• T-cells
• blood cells

The central nervous system consists of...

• the brain and nerves of the fingers and toes.
• all of the neurons in your body.
• the brain and spinal cord.
• the brain, heart, lungs, and spinal cord.
