All or Nothing
These chemical messengers carry signals across the synapse to begin depolarization
What are neurotransmitters?
This part of a neuron receives incoming messages from other neurons.
What are dendrites?
This is the anterior most lobe of the brain
What is the frontal lobe?
What is the corpus callosum?
This ion channel opens at -55mV
What is Na+?
This is the process of the membrane potential becoming more negative
What is repolarization?
This long extension carries neural impulses away from the cell body.
What is the axon?
This part of the brain processes visual information
What is the occipital lobe (or primary visual cortex)?
Damage to this area would result in poor decision making a planning
What is the frontal lobe?
This ion channel is closed at -70mV
Na+ and K+
This is the membrane potential when a neuron begins an action potential
What is -55mV
This fatty insulating layer helps neural impulses travel faster along an axon.
What is the myelin sheath?
This region is the anterior-most part of the parietal lobe
What is the somatosensory cortex?
Damage to this brain area would result in paralysis
What is the motor cortex?
This ion channel is open at +30mV
What is K+
This is the membrane potential when a neuron is at rest
What is -70mV
These structures at the ends of axons release neurotransmitters into the synapse.
What are terminal buttons (axon terminals)?
This area covers the dorsal surface of the temporal lobe
What is the auditory cortex?
Damage to this brain region our result in stumbling and jerky movement
What is the cerebellum
This ion channel opening causes depolarization
What is Na+
This is when a neuron's membrane potential becomes more negative than its resting potential
These gaps allow ion exchange between Schwann cells
What are Nodes of Ranvier?
This brain region is necessary for walking through doorways without running into the wall.
What is the parietal lobe?
What is Wernicke's Area?
This ion channel returns a neuron to resting potential
What is the Na/K+ Pump?
