Which outcome results when cholinesterase inhibitors are overdosed?

💡 Explanation

Skeletal muscle paralysis occurs when cholinesterase inhibitors overdose through **cholinergic crisis**, because excessive acetylcholine accumulates at neuromuscular junctions which overstimulates receptors producing the effect; therefore, paralysis rather than normal muscle function results since prolonged depolarization inactivates sodium channels.
