Decerebrate posturing most likely indicates injury to which part of the nervous system?

Explanation:
Decerebrate posturing signals brainstem injury, typically in the midbrain or pons. When the brainstem’s motor-regulating circuits are disrupted, the extensor pathways dominate and the arms and legs extend rigidly. This pattern reflects a severe neurological insult and tends to have a worse prognosis than injuries higher up in the brain (such as cortical injuries), which produce different posturing.
