Wof skeletal muscles is relaxed first by tubocurarine 
Select and explain. 
A. Respiratory muscles, B. Head and neck muscles, C. Finger muscles, D. Limb muscles
C: Finger muscles
Answer: C: Finger muscles 
Explanation: ACTIONS Skeletal muscles:- Intravenous injection of nondepolarizing blockers rapidly produces muscle weakness followed by flaccid paralysis. Small fast response muscles (fingers, extraocular) are affected first; paralysis spreads to hands, feet--arm, leg, neck, face--trunk--intercostal muscles--finally diaphragm: respiration stops. Recovery occurs in the reverse sequence; diaphragmatic contractions resume first. Ref:- kd tripathi; pg num:-350
