Neuron Structures
Branches that extend from the cell body?
What is Dendrites
Functions of the nervous system
Sensation, Integration, Response
Highly dangerous and malignant
What is Glioma
What is the resting membranes potential inside the cell compaired to outside?
What is -70mV
The ions that help repolarize neuron after action potential
what are Potassium Ions (K+)
Body of the cell
What is a Soma
The flow of electricity from one to another
What is Current
Typically are benign tumors
What is Neuroma
Potassium Equilibrium
-90mV
this opens when a specific chemical binds to the channel
What are Ligand-Gated Channels
What is Synapse
Sites between myelinated regions where signals are recharged
What are Nodes of Ranvier
Loss of communication due to damaged myelin-mediated insulation
What is Multipule Sclerosis
Sodium equilibrium
What is +55mV
gaps in the membrane that allows ion currents to pass directly into another
What is electrical synapse
Area where a signal is first generated
What is the Axon Hillock
regions of Axon covered in myelin
What are Internodes
Autoimmune reaction in demyelinating disease of PNS
What is Guillain-Barre Syndrome
Ion channels that open with physical changes (such as temperature, stretched, or pushed)
What is Mechanically-gated channels
these lead to hyperpolarization of postsynaptic
what is inhibitory neurotransmitters
A Fiber that emerges from from the cell body
What is Axon
neurons resting period after action potential
what is refractory period
Alzheimer's
Loss of Acetylcholine
This instance occurs when the voltage-gated potassium channels are open
What is Hyperpolarization
requires neurotransmitter to allow cell communication
what is chemical synapse
