Muscle spindle', 'role': 'user'}, {'content': 'Answer: A \nExplanation: Ans. a (Golgi tendon organ). (Ref. Ganong, Physiology, 21st ed. 133)The harder a muscle is stretched, the stronger is reflex contraction however, when tension becomes great enough contraction suddenly ceases & muscle relaxes. This relaxation in response to stronger stretch is inverse stretch reflex or autogenic inhibition.REFLEXES:.Sr. no.MonosynapticDisynapticPolysynaptic1.Stretch reflexInverse stretch reflexWithdrawal reflex (crossed extensor); all superficial reflexes2.Receptors in intrafusal fibresReceptors in golgi tendon organ-3.Afferent thro lalphaAfferent thro lb-4.NT-glutamateNT-glutamate-(Note -- Intrafusal fibres are nuclear bag and nuclear chain fibres)', 'role': 'assistant'}]
