Where do action potentials associated with heartbeat regulation originate?
the action potentials associated with heartbeat regulation originate in the SA node, I believe it is in somewhere in the wall of the right atrium of the heart
Action potentials originate at the?
Action potentials are how nerve impulses are transmitted from neuron to neuron. An action potential is formed when a stimulus to the nerve cell causes the membrane to depolarize and open all of its sodium ion channels toward the threshold potential.
The most rapid action potentials are conducted on?
thick, myelinated axons.
How does an action potential differ from a graded potential?
Action potentials also known as spikes, differ from graded potentials in that they do not diminish in strength as they travel through the neuron.
Can action potentials be summated?
no but generator potential can be summated

Do action potentials become weaker with distance?
action potentials are non-decremental and do not get weaker with distance.
Where does an action potential start?
Action potentials are generated on a part of the neuron called the 'axon hillock' - the proximal most portion of the axon.
What do intercalated discs transfer from cell to cell?
action potentials, ionic currents, the force of contraction and ionic currents and action potentials only

Communication in the nervous system depends on?
action potentials
Does nervous tissue generate action potentials?
Yes.
A nerve impulse consists of a wave of?
Action Potentials
Can action potentials be summated?
no but generator potential can be summated
