The brainstem is the stalk-like part of the brain that connects the cerebrum and cerebellum to the spinal cord. It includes the midbrain, pons, and medulla oblongata. It's like the trunk of a tree, connecting the branches to the roots. It controls vital functions like breathing, heart rate, and blood pressure. Damage can lead to severe disability or death. It is crucial for survival and basic bodily functions.
