Q11 answer is A , skeletal muscle are stimulated by the acetylcholine which is stored in the synaptic knob at the neuromuscular junction, action potential is not stored in signup techno it is travelled through nerve, calcium is acting on the actin not over the myosin for a power stroke.
Q12 answer is option b, just before releasing of acetylcholine at synaptic cleft the action potential is travel from axon hillock to up to the nerve terminal and that cause release of acetylcholine at neuromuscular junction.
Q13 answer is -action potential is located in the dendrites and it is coming from the previous neuron.
Acetylcholine is located in the in the cell body but it is synthesized due to the action of genes present in nucleus.
Calcium is present in the cell body of the neurone.
Q14 answer is True, acetylcholine is released from the synaptic vesicle into the synaptic cleft, there will there will be binding of acetylcholine to receptor present on the muscle membrane. Because the stimulation of the muscle tissue by depolarizing muscle membrane.
