KembaraXtra-Psychology – Brainstem
The brainstem is the elongated, stalk-like structure located at the base of the brain, forming the critical connection between the cerebral hemispheres and the spinal cord. Anatomically, it is composed of three major parts: the midbrain, the pons, and the medulla oblongata. Within these regions lie the nuclei of most of the cranial nerves, which regulate essential sensory and motor functions of the head and face. The brainstem plays a vital role in maintaining consciousness and regulating fundamental life-sustaining processes, including breathing, heart rate, blood pressure, swallowing, and other autonomic functions necessary for survival. Because it governs these vegetative processes, damage to the brainstem can be life-threatening. The term is also written as brain stem.
