Respuesta
-
membrane potential
Pregunta 11
Pregunta
During an action potential, the opening of [blank_start]potassium ion channels[blank_end] permits an [blank_start]outflow of potassium ions[blank_end], which eventually returns the membrane potential to its resting value.
Respuesta

potassium ion channels
-
outflow of potassium ions
Pregunta 12
Pregunta
During an action potential, the opening of [blank_start]sodium ion channels[blank_end] permits an [blank_start]inflow of sodium ions[blank_end], which depolarizes the neuron.
Respuesta
-
sodium ion channels
-
inflow of sodium ions
Pregunta 13
Pregunta
At terminal buttons, [blank_start]synaptic vesicles[blank_end] contain [blank_start]neurotransmitters[blank_end], which serve as chemical signals for communication between neurons.
Respuesta
-
synaptic vesicles
-
neurotransmitters
Pregunta 14
Pregunta
The neurotransmitter molecules released into a synaptic cleft can open up ion channels on the postsynaptic membrane, which permits [blank_start]ion flow[blank_end] across the postsynaptic membrane.
Respuesta
-
ion flow
Pregunta 15
Pregunta
After ion channels are opened up y neurotransmitter molecules, the flow of ions across the postsynaptic membrane could either have an [blank_start]excitatory[blank_end] effect, which makes the postsynaptic neuron more likely to fire, or have an [blank_start]inhibitory[blank_end] effect, which makes the postsynaptic neuron less likely to fire.
Respuesta
-
excitatory
-
inhibitory
