Charles Bell

Charles Bell was a Scottish surgeon and neuroscientist in the late 18th and early 19th centuries, renowned for his work on the nervous system. He identified the distinction between motor nerves, which control muscle movements, and sensory nerves, which transmit sensations like touch and pain. Bell also studied facial expressions and muscles, helping to explain how facial movements occur. His discoveries significantly advanced understanding of neuroanatomy and nerve function, laying the groundwork for modern neuroscience and medical diagnosis of nerve-related conditions.
