Electrochemical impulse :red_cross: How electric current is generated in the body.
Action potential : :red_cross:
The voltage difference across a nerve cell membrane when the nerve is excited.
Stimulated axon :check:
Depolarization :check:
Sodium-potassium pump :red_cross:
Located in the cell membrane, an active transport method that moves sodium ions out of and potassium ions into a cell against their concentration gradient.
Resting potential :red_cross:
Voltage difference across a cell membrane during the resting stage
Unstimulated axon :check:
Repolarization :check:
Polarized membrane :check:
Refractory period :check:
Hyperpolarized :red_cross: A Condition when the inside of the nerve cell membrane becomes more negative than the resting potential.
Threshold level :red_cross: Minimum level of a stimulus required to produce a response.
All-or-none response :red_cross: A nerve or muscle fibre responds completely or not at all to the stimulus.
Synaptic transmission :check:
Synapses :red_cross:
Small spaces between neurons or between neurons and effectors.
Postsynaptic neuron :red_cross:
Neuron that carries impulses away from the synapse.
Acetylcholine :red_cross:
Neurotransmitter released from vesicles in the end plates of neurons, that makes the postsynapatic membranes more permeable to sodium ions.
Cholinesterase :red_cross:
Enzyme, which breaks down acetylcholine, that is released from postsynapatic membranes in the end of plates of neurons shortly after acetylcholine.
Presynaptic neuron :red_cross:
Neuron that carries impulses to the synapse.
Neurotransmitters :red_cross:
Chemicals released from vesicles into synapses. Located in the end plates of axons.
Summation :red_cross: Effect produced by the accumulation of neurotransmitters from two or more neurons
