Which document provided the earliest known scientific descriptions of the brain and spinal cord?

• A. Edwin Smith Surgical Papyrus
• B. Hippocratic Corpus
• C. Galen's Anatomy
• D. Gray's Anatomy

Answer: (A)

The earliest scientific-style notes about the brain and spinal cord come from an ancient Egyptian medical text known as the Edwin Smith Surgical Papyrus. Dating to around 1600 BCE, it presents systematic observations of head injuries and their neurological effects, effectively treating the brain and spinal cord as distinct structures whose damage produces specific deficits. This makes it the oldest surviving document with clinical descriptions of the brain and spine. Later sources, like the Hippocratic writings, Galen’s anatomy, and much later Gray’s Anatomy, describe the brain and spinal cord as well but arrive centuries or millennia after the Egyptian text, so they cannot be the earliest.
