Amygdala

500

This part of the brain controls most of the involuntary body functions (breathing, etc…).

Brain Stem

Cellular

100

These cells transmit information throughout the nervous system.

Neurons

200

These neurons carry information to control movement.

Motor

300

These neurons carry information TO the brain.

Sensory

400

The part of the neuron that takes information away from the cell body.

Axon

500

The part of the neuron that receives information from other neurons.

Dendrite

Connect

100

Protects the brain.

Skull

200

This system works with the nervous system to control breathing.

Respiratory

300

This system works with the nervous system to control movement.

Muscular

400

Circulatory/Cardiovascular

500

This system works with the nervous system to control the flow of hormones in the body.

Endocrine

Random 1

100

This system is the “control center” of the body.

Nervous

200

This part of the nervous system connects the brain to the rest of the nerves in the body.

Spinal Cord

300

Neurons communicate using these types of impulses.

Electrical

400

This subdivision of the nervous system controls functions that happen automatically/involuntarily.

Autonomic Nervous System

500

This subdivision of the autonomic nervous system activates the “fight or flight” response (reactions to stressful/scary events).

Random 2

100

The nervous system is divided into how many main parts?

Two

200

This part of the nervous system is made up of the brain & spinal cord.

Central Nervous System (CNS)

300

This part of the nervous system is made up of the nerves that run throughout the body.

Peripheral Nervous System (PNS)

400

This feature of brain development allows us to create new pathways in the brain so we can change how we think & behave.

Neuroplasticity

500

This sudivision of the nervous system controls things we do by choice.

Somatic Nevous System
