Central muscle relaxants act by: (A) Decreasing muscle excitation, (B) Decreasing spinal polysynaptic reflexes, (C) Inhibiting spinal polysynaptic reflexes, (D) Decreasing nerve conduction
Answer is C. Refer KDT 6/e p 348 Centrally acting muscle relaxants reduce skeletal muscle tone by a selective action in the cerebrospinal axis, without altering consciousness They selectively depress spinal and supraspinal polysynaptic reflexes Polysynaptic pathways in the ascending reticular formation which are involved in the maintenance of wakefullness
