All of the following decrease skeletal muscle tone by CNS effects except____________?
Correct answer: A. D-tubocurarin
- A. D-tubocurarin
- B. Diazepam
- C. Beclofen
- D. Mephensin
Explanation
D-tubocurarine produces skeletal muscle relaxation by blocking nicotinic receptors at the neuromuscular junction, which is a peripheral action rather than a CNS effect. Diazepam, baclofen and mephenesin reduce muscle tone through central mechanisms.
