anatomy and physiology questions need help!!!!!!!!!!!!!!!!!!!!!!!!!!!!

1.) what would happen if a skeletal muscle were fully contracted and calcium was completely removed from the muscle cell in an infant?

2.) if a person is given a drug that interferes with the action of acetylcholinesteras e at the terminal synapses, what would be an affect?

3.)the following experiments were performed on a single unit smooth muscle in the gastrointestinal tract. the results are:
a.) electrical stimulation of the autonomic nerve serving the smooth muscle produced a contraction
b.)applying a drug that blocks the voltage gated sodium channels in the sarcocolemma of the smooth muscle cell lead to a failure to contract upon stimulation the autonomic nerve
c.) applying a drug that blocks the acetylcholine receptors did not prevent the muscle from contracting

-from these observations describe how stimulation of this autonomic nerve brings about the concentration of this smooth muscle?
