The brain and the spinal cord are part of this section of the nervous system.
What is the central nervous system?
100
These are nerve cells that run through our bodies.
What are neurons?
100
These are chemicals that send messages between neurons.
What are neurotransmitters?
100
This regulates our internal functions and how we react to the outside world.
What is our nervous system?
100
This chemical sends messages from neuron to neuron.
What are neurotransmitters.?
200
Regulates our internal functions. It is also involved in how we react to the outside world.
What is the nervous system?
200
This is the gap between the axon terminals of one neuron and the dendrites of another.
What is the synapse, or synaptic gap?
200
Neurotransmitters cross this gap when they send messages between neurons.
What is the synapse, or synaptic gap?
200
This part of the neuron produces energy that fuels the neuron's activity.
What is the cell body?
200
These two parts of our body make up the central nervous system.
What is the brain and spinal cord?
300
This section of the nervous system is activated when we go into "fight or flight" mode.
What is our sympathetic nervous system?
300
This is the direction that information travels along the neurotransmitter. A message is received at the _____ and sent to the next neuron by the _____.
What are dendrites to axon terminals?
300
This is the area of the neuron from which neurotransmitters are released.
What are axon terminals?
300
These are cells that run through our whole body and communicate with each other.
What are neurons?
300
This part of the nervous system restores the body's reserve of energy after intense activity.
What is the parasympathetic nervous system?
400
This part of the nervous system regulates vital functions, such as heartbeat, breathing, digestion and blood pressure.
What is the autonomic nervous system?
400
This is the function of the myelin sheath.
What is to insulate the axon and speed up messages sent by the neuron?
400
This is what happens to neurotransmitters once they cross the synapse, or synaptic gap.
The neurotransmitter chemicals are converted to electricity and sent from the dendrites, through the axon, to the axon terminal
400
This part of the neuron receives information from other neurons and passes those messages through the cell body.
What are dendrites?
400
This part of your nervous system regulates vital functions like heartbeat, blood flow and breathing.
What is the autonomic nervous system?
500
These are the functions of the somatic nervous system.
The somatic nervous system carries messages from voluntary muscles and sense organs. It is activated by pain, touch, temperature and body position.
500
This is the form in which messages travel through the neuron.
What is electricity, or electric impulses?
500
These are the three neurotransmitters that fire in our brain when we are in love.
What are dopamine, norepinephrine and oxytocin?
500
These are the symptoms of a concussion.
What is dizziness, blurred vision, headaches, nausea, vomiting, short term memory loss...
500
This is what your nervous system does when a WOLVERINE ATTACKS YOU.
What is shuts down digestion, increases heart rate, raises blood pressure....
