Which ion causes neurotransmitter vesicles to fuse with the axon's membrane during the conduction of a nerve impulse from one neuron to the next?
Calcium ions are responsible for triggering the fusion of neurotransmitter vesicles with the axon's membrane during the conduction of a nerve impulse. The influx of calcium ions into the neuron's terminal triggers the release of neurotransmitters into the synaptic cleft.
What is the membrane of a nerve cell is comprised of?
Its main function is to propagate the action potential (the 'impulse') along the length of the axon.
What is the difference between impulse conduction and transmission?
Impulse conduction refers to passage of impulse within the same cell. Where as transmission as the name implies, is concerned about passage of impulses either chemical or electrical from one cell to another.
Is the term for a delay or interruption in conduction of the electrical impulse in the myocardium?
The term for a delay or interruption in conduction of the electrical impulse in the myocardium is "heart block." Heart blocks can range from first-degree (mildest) to third-degree (most severe) based on the extent of conduction disruption in the heart's electrical system.
What is the impulse conduction through a reflex arc?
nociceptors and mechanoreceptors (respond to touch, temp and pain)

Which ions causes neurotransmitter vesicles to fuse with the axons membrane during the conduction of a nerve impulse from one neuron to the next?
I believe it's Na+
What is impulse conduction?
Party of nervous
Why is the term action potential used to describe a nerve impulse?
It is a difference in charge supplied by ion position. In resting potential the tendency is for the inside of the cell membrane to have a negative ionic charge, while the outside of the membrane has a positive charge. The change, back and forth in these two charge potentials is the conduction of charge down the neuron and is called the action potential.
What kind of neurons does impulse conduction occur in the fastest?
nig
What is the difference between impulse conduction and transmission?
Impulse conduction refers to passage of impulse within the same cell. Where as transmission as the name implies, is concerned about passage of impulses either chemical or electrical from one cell to another.
What features of nerves improve impulse conduction velocity?
myelin sheaths
Is the velocity of a nerve impulse greater than electrical conduction's?
yes
When current leaps across an insulating myelin sheath from node to node the type of impulse conduction is called what?
Saltatory Conduction
What is the point in the intrinsic conduction system where the impulse is temporarily delayed?
Av node
Can the depressant effect of alcohol interfere with the conduction of the electrical impulse of the heartbeat?
false
