Central muscle relaxants act by -: (A) Decreased nerve conduction, (B) Inhibits spinal polysynaptic reflexes, (C) Block conduction across NM junction, (D) CNS depression
Answer is B. Ans. is 'b' i.e., Inhibits spinal polysynaptic reflexes Centrally acting muscle relaxants selectively depress spinal and supraspinal polysynaptic reflexes involved in the regulation of muscle tone without significantly affecting monosynaptic mediated stretch reflex.
