How did the action potential generated with the unheated rod compare to the generated with the heated rod?

Heat information is conducted through neurones. Higher frequency action potentials are perceived in the brain as a hotter stimulus. So the heated rod would have sent higher-frequency action potentials than the cool rod would have.

The action potential is generated when a stimulus?
When a stimulus stimulates a neuron above the threshold, the action potential is generated.
Where in a neuron can an action potential be generated?
axon hillock
What is missing in the receptive region which prevents an action potential from being generated there?
voltage gated ion channel
What determines if an action potential is initiated in the postsynaptic neuron?
Every time neurotransmitter is released from the presynaptic neuron it generates an excitatory post synaptic potential(EPSP) in the postsynaptic neuron. When the EPSP is greater than the threshold for excitation an action potential is generated.
Why is the action potential generated in neurons only?
may be there are specific arrangement of sodium and potassium ion channels in neurons which is not found in any other cell andthis arrangement is necessary for action potential generation but i am ot sure what kind of arrangement is needed for action potential generation and what kind is presentr in neurons and other cells .
The action potential is generated when a stimulus?
When a stimulus stimulates a neuron above the threshold, the action potential is generated.
Where in a neuron can an action potential be generated?
axon hillock
What ion is released when action potential is generated on the sarcolemma?
Potassium.
What happens to the heart when an action potential is generated in the SA node?
it contracts
What happens in the heart when an action potential is generated in the SA node?
Myocardial contraction
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 is missing in the receptive region which prevents an action potential from being generated there?
voltage gated ion channel
How do the waves of depolarization generated by the autorhythmic cells spread to the muscle cells?
Gap Junctions in the cell spread the action potential to nearby cells.
What determines if an action potential is initiated in the postsynaptic neuron?
Every time neurotransmitter is released from the presynaptic neuron it generates an excitatory post synaptic potential(EPSP) in the postsynaptic neuron. When the EPSP is greater than the threshold for excitation an action potential is generated.
Each normal heartbeat in initiated by the?
Each heartbeat begins with an action potential generated at the sinoatrial node or simple call the SAnode.

Action potential is generated by the movement of?
An action potential is propagated in a neuron through the activation of various voltage-gated and ligand-gated ion channels. Examples include sodium and calcium channels and nicotinic-acetylcholine receptors.
