Action Potential
The direction the action potential travels
What is toward the axon terminals?
Vesicles release this into the synapse
What are neurotransmitters?
This is where recptor molecules in the postsynaptic membrane are located
What is the dendrites and cell body?
When the resting potential occurs
What is when a neuron at rest?
This seperates the presynaptic and postsynaptic neuron
What is the synaptic cleft?
This is where the action potential originates
What is the axon hillock?
The channel that opens at the threshold
What is a Na+ voltage-gated channel?
The breif change in membrane potential because of a neurotransmitter
What is postsynaptic potentials?
The charge of the cell during resting potential
What is negatively charged compared to outside?
These are substances that mimic neurotransmitters
What are agonists?
This triggers the action potential
What is the sum of IPSP and EPSP?
The voltage of the threshold
What is -40mv?
This pushes postsynaptic cell closer to thresholod
What is the excitatory postsynaptic potential (EPSP)?
The channel that is open at rest
What is leaky k+ channels?
This process absorbs neurotransmitters back into the axon terminal they were released from
What is reuptake?
The average peak of the action potential
The channel that opens when the action potential reaches the axon terminal
What is Ca2+ voltage gated channel?
This hyperpolorizes the postsynaptic cell
What is the inhibitory postsynaptic potential (IPSP)?
Average resting potential of cells
These are the classic synapses
What are axo-dendritic synapses and axo-somatic synapses?
The reason action potential is only conducted in one direction
What is the cell membrane in the wake of the action potential being in the refractory phase?
Where channels are located on the axon
What is the Nodes of Ranvier?
This determines the action of the neurotransmitter
What is the nature of postynaptic receptors?
This approximates a cells resting potential
What is the equlibrium potential?
This disability disrupts neural communication and the balance of excitation and inhibition
What is autism?
