Once you have the action potential made from the influx of Na traveling down the axon depolarizing it. The action potential reaches the axon terminals, the depolarization causes Ca2+ to enter the cell and that causes the release of the neurotransmitters out of the axon terminals and into the dendrites of the next axon to continue the signaling pathway.
What else can I help you with?
Is calcium a neurotransmitter?
No, calcium itself is not a neurotransmitter BUT it is highly important in the process of the action potential. The action potential triggers the influx of calcium at the end of the terminal bouton, causing the influx of Ca2+ into the cell and this triggers for the release of the neurotransmitter. :)
The small spaces between neurons where neurotransmitters are released are called alveoli?
The SYNAPSE is the very small space between two neurons and is an important site where communication between neurons occurs.
What is the role of CA2 plus in action potential?
Calcium ions (Ca²⁺) play a crucial role in the generation and propagation of action potentials, particularly in neurons and muscle cells. When an action potential reaches the axon terminal or the sarcolemma, voltage-gated calcium channels open, allowing Ca²⁺ to flow into the cell. This influx of calcium triggers the release of neurotransmitters in neurons and initiates muscle contraction in muscle cells. Additionally, calcium is involved in the repolarization phase of the action potential by influencing various ion channels and signaling pathways.
What part of a neuron would probably be affected most by the application of Novocain?
Novocain blocks calcium channels. Voltage-dependent calcium channels are a group of ion channels found in the membrane of excitable cells such as the axons of neurons and glial cells.
The nervous system cells or neurons do not contain centrioles These neurons most likely could not what?
Neurons lacking centrioles are unlikely to be able to undergo cell division. Centrioles are important for organizing the cell's cytoskeleton during mitosis, and their absence could hinder cell division in neurons.
What is most likely to imitate calcium's role in the function of neurons?
Magnesium is most likely to imitate calcium's role in the function of neurons. Magnesium can affect synaptic plasticity and neurotransmitter release, similar to calcium.
In a neuron where are voltage-gated calcium channels located?
Voltage-gated calcium channels in neurons are mainly located in the axon terminals, where they play a key role in mediating calcium entry upon depolarization. This influx of calcium triggers neurotransmitter release at the synapse, allowing for communication between neurons.
Why is calcium so important?
Your question needs context. Why is calcium so important to what?

Which element is most likely to imitate calciums role in the function of neutrons?
There is no real elemental role in the function of neutrons. Did you mean neurons?
One important difference between autonomic neurons and somatic neurons is the presence of?
Autonomic neurons control signals to and from the brain to smooth and cardiac. Whereas Somatic neurons control the signals to and from the skeletal system and brain.
Which electrolyte is important for the activity of the heart muscle?
There are four electrolytes that are important to heart function, potassium, calcium, sodium and magnesium. Calcium is important in the actual contraction of the heart.

How is calcium used in the muscles and the neurons?
the chemically driven force behind contractions ...assist actin and myosin to connect so contraction can occur
How much communication is relevant in engineering?
As important as neurons are important for ur body to function properly
How many types of neurons?
There are three types of neurons. 1.Sensory neurons: which carry impulses from the sense organs to the brain and spinal cord. 2.Motor neurons : which perform an opposite function to that of sensory neurons by carrying impulses from the brain and spinal cord to muscles and glands. 3. Inter neurons : which connect sensory and motor neurons and carry impulses between them.
