How would a drug that competes with ACh for receptors at the motor end plate affect skeletal muscle? It would:
Produce uncontrolled muscle spasms
Cause the muscles to contract and be unable to relax
Cause muscles to relax and be unable to contract
Make the muscles more excitable
Ref: KD Tripathi pharmacology 7th edition (page.no: 58) Anticholinergic drugs compete with acetylcholine for receptors at NM junction . Anticholinergic opposes the action of Ach causing relaxation of the muscle.
