Rationale 1: The exact mechanism by which skeletal muscle relaxants work is not fully understood. It is believed that they inhibit upper motor neuron activity, causing CNS depression.
Rationale 2: Stimulation of the peripheral nervous system is not the mechanism of action of muscle relaxants.
Rationale 3: Muscle relaxants do not increase the amount of neurotransmitter.
Rationale 4: Muscle relaxants do not stimulate motor activity in the brainstem.
