What distinguishes grey matter from white matter in the brain?
Understand the Problem
The question is asking us to differentiate between grey matter and white matter in the brain, specifically focusing on their structural and functional characteristics.
Answer
Grey matter has neuronal cell bodies; white matter has myelinated axons.
Grey matter consists of neuronal cell bodies and dendrites, whereas white matter consists primarily of myelinated axons, which transmit impulses over long distances.
Answer for screen readers
Grey matter consists of neuronal cell bodies and dendrites, whereas white matter consists primarily of myelinated axons, which transmit impulses over long distances.
More Information
Grey matter processes information in the brain using neuronal cell bodies, while white matter is responsible for communication between different brain regions due to its myelinated axons.
Tips
Common mistakes include confusing the functions of grey and white matter or thinking they both consist of the same type of neuronal structures.
