What is the primary mode of action of curare?
A) It decreases the number of functional receptors on the muscle cell by the process of phagocytosis, which impairs the ability of neurons to respond to acetylcholine.
B) It blocks the sodium channels in the axon of the presynaptic axon.
C) It blocks communication at the neuromuscular junction by preventing acetylcholine from binding to nicotinic cholinergic receptors.
D) It decreases the amount of acetylcholine released from the synaptic terminal.
E) It causes the degradation of the enzyme acetylcholinesterase.
