Membrane potential depolarizes, Na+ channels open, Na+ current increases, _______.Group of answer choicesK+ channels openNa+ channels closeNa+ current decreaseNa+ current increasemembrane potential hyperpolarizes

When traveling along an axon, the cell membrane immediately ahead of an action potential depolarizes because of _________blank.Multiple Choicethe sodium/potassium pumpmembrane receptorsdiffusion of sodium currentdecreased membrane permeabilitypotassium efflux

Hyperpolarization occurs because voltage-gated Blank______ channels stay open longer than required to reach resting membrane potential. Multiple choice question.sodiumpotassium

A neuron receives a series of stimuli that increases the membrane permeability of Na+, but not enough to cause membrane potential to surpass -55mV. This neuron is said to be __________Blank because it received a subthreshold stimuli.Multiple Choicerefractoryamplifiedgradedfacilitated

During these stages of an action potential, identify whether the voltage-gated sodium (Na+) channels are open or closed:RepolarisationAnswer 1 Question 13DepolarisationAnswer 2 Question 13RestAnswer 3 Question 13Hyperpolarisation

The membrane potential at which voltage-gated sodium channels open is called .
