Neurons
Neurons that send signals to muscles.
What are motor neurons?
Resting membrane potential
The gap between two neurons.
Division of the PNS that controls smooth muscle.
What is the autonomic nervous system?
Part of the brain that controls heart rate and breathing rate.
What is the medulla oblongata?
Action potential "jumps" from node to node.
What is saltatory conduction.
The concentration of this ion is greater inside of the axon that it is outside.
What is potassium?
This ion causes vesicles containing neurotransmitter to fuse with the presynaptic membrane.
What is Ca2+?
Part of the reflex arc that detects a stimulus.
What is a receptor?
Lobe of the brain that is responsible for vision.
What is the occipital lobe?
Interneurons are mostly contained within this area of the spinal cord.
What is gray matter?
Name of the stage in an action potential where there membrane potential returns to the resting membrane potential.
What is repolarization?
The two effects neurotransmitters have on action potentials.
What are excitatory and inhibitory effects.
Division of the PNS that is responsible for the "flight or fight" response.
What is the sympathetic nervous system?
Region of the brain that is very important for maintaining homeostasis.
What is the hypothalamus?
Autoimmune disorder that destroys parts of the neuron.
What is multiple sclerosis.
Length of time in which sodium channels are closed and an action potential can not be generated, even if there is a stimulus.
What is the refractory period?
Excitatory neurotransmitters typically bind to these types of channels.
Name of the neurotransmitter that causes a more relaxed state.
What is acetylcholine?
The causes of Alzeimer's disease.
What are protein buildups (plaques) in the neuron and tangled axons.
These neurons usually do not contain myelin sheaths.
What are interneurons.
The peak membrane potential of an action potential.
What is +35mV?
This neurotransmitter is important for learning and memory.
What is glutamate.
Increased heart rate and breathing rate; increased blood flow to skeletal muscles.
What are effects of the sympathetic nervous system (or norepinephrine).
Damage to this area of the brain would make coordinated muscle control difficult.
What is the cerebellum.
