the relationship between damage to different parts of the brain and coma
the relationship between damage to different parts of the brain and coma: the integrity of the brain structure is a necessary condition for the existence of human consciousness. damage to the structure and function of the brain due to various reasons will cause coma of varying degrees. medulla oblongata and caudal pons: if the lesion is in the medulla oblongata and caudal pons (below the trigeminal nerve) and does not cause coma, sometimes decerebrate stiffness may occur, but the patient is conscious, and the clinically seen infratentorial posterior fossa occupies cerebral ischemia and hypoxia are often caused by increased intracranial pressure, cerebral herniation, etc., and eventually cause coma. however, the coma caused by these diseases is not caused by the medulla oblongata or the caudal pons itself. from the beginning of the pons to the end of the midbrain: lesions occurring from the beginning of the pons to the end of the midbrain can cause coma, often accompanied by bilateral pupils of pinpoint size, loss of light reflex, central hyperthermia, etc. ,
