Final answer:
The brainstem is responsible for relaying sensory and motor information between the brain and spinal cord.
Step-by-step explanation:
The brain stem is a conduction pathway between higher and lower brain centers and houses nuclei for cranial nerves V-VII. It is responsible for relaying sensory and motor information between the brain and spinal cord. The brain stem consists of the midbrain, pons, and medulla oblongata, and it plays a crucial role in controlling vital functions such as breathing, heart rate, and blood pressure.
