[{'content': 'Reflex is characterised by all except \nSelect and explain. \nA. Fractionation, B. Occlusion, C. Prepotentiation, D. Minosynaptic', 'role': 'user'}, {'content': 'Answer: D \nExplanation: (D) Minosynaptic > The basic unit of integrated reflex activity is the Reflex arc.# Monosynaptic reflexes: Simplest reflex arc is one with a single synapse between afferent & efferent neurons, such arcs are monosynaptic.# Polysynaptic reflexes: Reflex arcs in which one or more interneurons are interposed between the afferent & efferent neurons are polysynaptic. The number of synapses in the arcs wherein from two to many hundreds.> In both types but especially polysynaptic reflex arcs, activity is modified by spatial & temporal facilitation, occlusion, subliminal fringe effects & other effects.> Properties of Reflexes are Delay Summation Occlusion Subliminal fringe/fractionation Habituation and sensitization', 'role': 'assistant'}]
