Nervous System Test

This system receives information about what is going on inside and outside of your body. Then, it processes that information and forms a response to it.

• Muscular System

• Skeletal System

• Cardiovascular System

• Nervous System

• Respiratory System

These carry messages, or impulses, from one part of your body to another:

These carry nerve impulses, or messages toward a neuron's cell body

The three types of neurons are Sensory Neurons, Interneurons and:

• Myelin Neurons

• Engine Neurons

• Synapse Neurons

• Axon Neurons

• Motor Neurons

These take impulses or information away from the cell body:

These cover some axons and increase the speed of the impulse:

• Myelin Sheath

• Dendrites

• Meningitis

• Brain Stem

• Synapse

This is the control center of the body. It includes the brain and spinal cord:

• Lymphatic System

• Endocrine System

• Central Nervous System

• Digestive System

• Respiratory System

How many neurons make up the brain?

• 1 million

• 100 million

• 1 billion

• 100 billion

• 1 trillion

This region of the brain makes up about 85% of the brain's weight. Divided into left and right hemispheres, it controls movement, speech and abstract thought.

This region of your brain coordinates movement and balance.
