Q

what 2 different types of tissue is the cerebrum composed of?

A
  • grey matter: forms surface of each cerebral hemisphere (cerebral cortex), associated with processing and cognition
  • white matter: forms bulk of deeper parts of brain, consists of glial cells and myelinated axons that connect various grey matter areas

Q

what are the main sulci?

A
  • central sulcus: groove separating frontal and parietal lobes
  • lateral sulcus: groove separating frontal and parietal lobes form temporal lobe
  • lunate sulcus: groove located in occipital cortex
