[{'content': 'True about decoicate rigidity? \nSelect and explain. \nA. Removal of cerebral coex and basal ganglia, B. Flexion of lower limbs & extension of upperlimbs, C. Rigidity is less pronounced than decerebrate rigidity, D. None of the above', 'role': 'user'}, {'content': 'Answer: C \nExplanation: Decoicate Rigidity Made by removing whole cerebral coex but leaving basal ganglia intact. Characterised by flexion of upper extremities at elbow & extension of lower extremities. Flexion due to rubrospinal tract excitation of flexors in upper extremities & hyperextension of lower extremity. Decoicate animal doesnot have intense hypeonia as decerebrate animal.Due to intact basal ganglia in decoicate animal.
