Those should all be right but I'm 98% sure about the last one.
Answer:
The correct answer will be option-E.
Explanation:
Acetylcholine belongs to a group of chemical messengers which also acts as neurotransmitters in the synaptic transmission of the signals.
The acetylcholine is present in the vesicles in the synaptic knob which when released at the neuromuscular junction cause the contraction of the skeletal muscle along with cardiac and smooth muscle.
The mechanism of action is different in different muscles as the neurotransmitter binds to the nicotinic receptors present on the motor endplate and opens ligand-gated sodium channels.
In smooth and cardiac muscle it binds to the muscarinic receptors and cause the release of calcium ions and potassium ions respectively and cause muscle contraction.
Thus, option-E is the correct answer.
