Intro to the Nervous System

Nerve Cells are also called:

• Capillaries

• Synapses

• Neurons

• Glial cells

The part of the neuron that receives signals is the:

• Axon
• Dendrite
• Axon Terminal
• Cell Body

The electrical messages sent through the nervous system are called ____________. 

• Impulses
• Neurons
• Dendrites
• Transmissions

what might be a job of a motor neuron?

• connecting to a muscle and helping you move

• connecting within the brain to help you make a decision

• sending a message toward your brain from a pain receptor in your skin

• all of these

What is the primary function (purpose) of the human nervous system ?

• Helps blood circulate through the body and allows for cellular respiration to take place.

• Uses electrochemical signal to help parts of the body communicate with each other and react rapidly to changes both inside and outside the body.

• Provides support to the muscles and glands and communicates through chemical signals released into the blood stream.

• Allows for problem solving and the ability to read and write.

Something that makes an organism react in a certain way. This can be internal or external.

• response
