Nervous System/Neurons Brain Pop

What might happen if your body lacked neurotransmitters?

• Your nerve cells could not communicate with one another.
• Impulses could not travel along your nerve cells.
• You would not be able to touch the objects that surround you
• Your nerve cells would begin dying off

How are neurotransmitters different from the impulses that travel along the bodies of nerve cells?

• The impulses are electrical; neurotransmitters are chemical.
• The impulses travel at a faster rate than neurotransmitters
• The impulses send signals from the body to the brain; neurotransmitters send signals from the brain to the body
• The impulses occur constantly; nuerotransmitters are released only occasionally.

Which process is governed by the autonomic nervous system?

• writing
• chewing
• breathing
• walking

If an area of your body is particularly sensitive, what can you conclude about that area?

• It contains more skin cells than other areas of your body.
• It contains more nerve endings than other areas of your body.
• It conducts electricity better than other areas of your body.
• It contains more neurotransmitters than other areas of your body.

A disorder called CIPA prevents certain people from feeling pain. What can you infer about these people?

• They are capable of amazing feats of strength
• They often injure or burn themselves without reaslizing it.
• Their brains do not function properly, so they can't think clearly.
• They tend to live extremely long lives.

Which phrase best describes your entire nervous system?

• Extensive and complex
• Localized and inefficient
• Unicellular and microscopic
• Mindless and automatic

An impulse traveling through your nervous system is most similar to:

• A feather floating on the breeze
• A noise traveling through the air
• An electric signal traveling through a series of telephone lines
• A truck driving down an interstate highway

_________ send information; _________ receive information.

• Terminals; dendrites
• Somas; impulses
• Processes; sheaths
• Membraines; myelin sheaths

What is the main purpose of the myelin sheaths around your neurons?

• They convert chemical signals into electrical signals
• They receive information from neighboring neurons
• They convert electrical signals into chemical signals
• They quicken the speed at which nerve impulses travel

Where can you find a synapse?

• Inside the nucleus of a neuron
• Between a neuron's dendrite and its terminal
• between seperate neurons
• surrounding the body of a neuron
