The AV (atrioventricular node). Electrical conduction is slowed down at this node, and half the time of each action potential is spent on getting the signal through the AV node. This delay is to allow the ventricles to fill completely with blood before they get the signal to contract.

Which part of the heart encases the heart in a tough outer membrane?
Which part of the heart encases the heart in a tough outer membrane?
Which part of the heart makes the heartbeat sound?
A heartbeat produces the familiar "LUB-DUP" sounds as the chambers contract and the valves close. The first heart sound, "lub," is heard when the ventricles contract and the atrioventricular valves close. This sound last longest and has a lower pitch. The second heart sound, "dub," is heard when the relaxation of the ventricles allows the semilunar valves to close.
What part of the heart is most often associated with heart murmurs?
valves
Which parts of the heart that sends blood to the brain?
left part of heart
What is the septal fibrosis of the heart?
It is a fibrosis (formation of scar tissue) in septum, a part of the heart that separates left and right part of the heart. It is usually a consequence of a viral infection.
Which part of plot is the longest?
rising action.
Which part of the neuron can propagate an action potential?
The axon is the part of the neuron that can propagate an action potential. This process relies on the opening and closing of ion channels along the axon membrane to allow the action potential to travel from the cell body to the axon terminals.
What part of the brain controls posture?
Action potential in the brain
What part of brain controls posture?
Action potential in the brain
Which part of the neuron is capable of generating an action potiental?
The axon hillock is the part of the neuron that is capable of generating an action potential. It integrates incoming signals from the dendrites and, if the threshold is reached, triggers the action potential to be propagated down the axon.
During depolarization of action potential the outer part of axon becomes?
Negative
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 part of the body did early philosopher think was the seat of thought and action?
Heart
When action potential generate the internal part of the axon becomes______ due to influx of sodium?
Positive
What is the longest part of the cell part?
the longest part of the cell cycle is Interphase
What part of the neuron can conduct an action potential?
The axon of a neuron is responsible for conducting an action potential. This is made possible by the presence of voltage-gated ion channels along the axon membrane that allow for the propagation of electrical signals.
What does propogation of an action potential mean?
Propagation of an action potential refers to the transmission of the electrical signal along the length of a neuron's axon. This is achieved through a series of depolarization and repolarization events that allow the action potential to travel in a rapid and coordinated manner from the cell body to the axon terminals. The propagation process ensures that information is effectively communicated from one part of the neuron to another.
