Question

Quizplus · Accepted Answer

Small signals in a synapse that don't reach threshold but can add together are called graded potentials. They are changes in membrane potential that vary in size and are able to summate to reach threshold and generate an action potential. Receptor potentials are specific to sensory neurons and are generated when a stimulus is detected. Action potentials are a type of electrical signal that travels down the axon of a neuron. Resting potentials are the steady state of the membrane potential when the neuron is not actively sending signals.
