Excitation ResetExplanation / Answer
1.
calcium
in the selected node voltage gated Calcium channel are present in which are opens up by the change and the voltage of that particular region. the allows the entry of calcium into the synaptic knob.
2.
contraction.
the muscle contraction is a process in which neurone cells transmits the signal to the muscles for contraction. muscle cells release signal molecule with allows activation of muscle receptors for further muscle contraction process.
on the membrane of muscles calcium channels are present which leads to entry of calcium into the muscle cells.
3. Acetylcholine.
Neuron cell releases acetylcholine molecule which is accepted by acetylcholine gated calcium channels and leads to opening of calcium channels.
4.
Excitation process.
5. Action potential.
The complete process of muscle contraction is: neurones cells have acetylcholine containing vesicle which is formed by the genes present in neurone cell. These vesicle are transferred towards the synaptic knob and releases acetylcholine molecules at the surface of muscles.
Muscle membranes have acetylcholine gated calcium channels which aare opened by the acetylcholine.
TThe entry of calcium entry of calcium into the muscle cell leads to muscle contraction.
