White matter - ANSWER the myelinated axons of neurons
Outermost surface of the brain (cerebral cortex) is structured to contain grooves and
dips of corrugated wrinkles within the brain tissue that provide _______________________ -
ANSWER anatomical landmarks or reference points. It also increases brain surface
area to expand working area and communication area
Grooves and dips of brain are named by________ & __________ - ANSWER size and depth
