The 'pons varolii' is an older term, now simply called the pons, a key structure in the brainstem. It connects the cerebrum, cerebellum, and spinal cord, acting as a relay station. It's like an old name for your favorite app – same function, just a different label. It regulates vital functions such as sleep, breathing, and sensory information. While the full term isn't used much, understanding it helps with historical context. 'Pons' is preferred now.
