Brain
Stimuli
100

Signals from the environment that activate neurons.  

Stimuli

100

Nerve cells that send and receive messages throughout the body.

Neurons

100

What is the system that serves as the body's command center?

What parts of the body does this include?

The Central Nervous System, which includes the brain and the spinal cord.

100

The part of the brain that controls the spinal cord and many involuntary activities, like breathing and heart rate.

 Medulla

100

A word that describes the reaction to stimuli.

Response

200

The receiving neuron recognizes and processes the message.

Receptor sites

200

The long, thin fiber of a neuron that transmits signals to other neurons.

Axon

200

What is the system that serves as the informational highway?

Where do these nerves transmit information from and to?

The Peripheral Nervous System transmits electrical signals from all over the body to the central nervous system.

200

The part of the brain that controls voluntary movements, the senses, and thought.

Cerebrum

200

Type of stimuli by smell and taste.

Chemical

300

Finger-like structures of a neuron that receive electrical signals.

Dendrite

300

A wave of electrical activity transmitted between neurons.

Nerve impulse

300

Your heart rate increases during a stressful situation. This part of the nervous system releases hormones, such as adrenaline, which increase heart rate and blood flow. 

Hint: an involuntary movement

the Peripheral Nervous System 

300

The part of the brain that keeps the body in balance.

Cerebellum

300

Type of stimuli by touch, pressure, and sound.

Mechanical

400

The places where neurons connect and communicate with each other.

Synapse

400

An involuntary response to an outside stimulus.

Withdrawal reflex

400

A person suffers a head injury, resulting in a concussion. What part of the nervous system would this affect?

The Central Nervous System

400

This part of the brain is necessary during a ballerina's performance. 

Cerebellum 

400

Type stimulated by light

Electromagnetic  

500

Nerves that transmit signals to skeletal muscle, causing movement.

Motor nerves

500

Nerves that receive sensory stimuli, such as how something feels.

Sensory nerves

500

You decide to pick up a can of soda. What part of the nervous system would this involve?

The central nervous system and the peripheral nervous system. 

500

Your blood pressure involves what part of the brain?

Medulla

500
