En esta lección vamos a discutir los impulsos nerviosos y los potenciales de acción.
A nerve impulse.
The part of the neuron that consists of the axon where action potentials propagate away from the trigger zone toward the axon endings.
The region of a neuron where signals enter.
The part of the neuron that consists of the axon endings where signals are sent on to another neuron or to a gland or muscle cell.
The steady voltage difference that occurs across a neuron’s membrane when it is not being stimulated.
A protein that pumps sodium potassium against their concentration gradients to restore the resting membrane potential following an action potential.
The minimum voltage shift across a membrane required for an action potential to take place.
The part of the neuron located at the base of the cell body that initiates action potentials.
