Neuroglia
Ion Channels
Action Potential/Nerve Impulse
Synpase Transmission
Neurotransmitters/Disorders
100
Neuroglia makes up this amount of the Central Nervous System.
What is half?
100
This type of ion channel opens in response to change in membrane potential
What is a voltage-gated channel?
100
Anything that causes changes in a cell.
What is a stimulus?
100
The union of two neurons or a neuron and its effector.
What is a synapse?
100
Most well known neurotransmitter.
What is Ach?
200
This part of neuroglia contains all the myelinated axons.
What is white matter?
200
This type of channel alternates between open/closed. Na+/K+ pump is an example.
What is a leakage channel?
200
When a stimulus will be strong enough to cause an action potential or none at all.
What is the threshold (or All-or-None principle)?
200
The neuron found prior to the synapse?
What is presynapse?
200
One of the two neurotransmitters associated with excitement.
What is Glutamate or aspartate?
300
This part of neuroglia contains all the unmyelinated axons, dendrites, and other parts.
What is gray matter?
300
This type of channels opens/closes in response to chemical signal
What is a ligand-gated channel?
300
The number of the threshold.
What is -55mV
300
The neuron found after the synapse.
What is postsynaptic?
300
The neurotransmitter associated with Temperature; Apetite; Onset of sleep.
What is Serotonin?
400
These are multilayered lipid and protein covering around neurons
What are myelin sheaths?
400
This type of channel open in response to mechanical stimulus
What is a mechanically-gated channel?
400
The mode in which impulses move from axon hillock to terminal.
What is propagation (conduction)?
400
The small gap between membranes of two neurons filled with fluid
What is synaptic cleft?
400
A natural painkiller.
What is Endorphins
500
These are gaps within myelin sheath.
What are the Nodes of Ranvier?
500
A protein that binds to a receptor in a ligand-gated channel
What is a ligand?
500
Conduction in which adjacent Na+ voltage-gated channels open along membrane.
What is Continuous?
500
The element most commonly used in the transmission of an impulse across the gap.
What is Ca+?
500
A neurological disorder with short, recurring, periodic attacks of motor, sensory, or psychological malfunction.
What is epilepsy?
