Gyrus - answer✔folds of the cortical region
Fissures - answer✔deepest grooves between folds
Sulcus - answer✔shallower grooves between folds
Longitudinal fissure - answer✔divides the cerebrum into right and left cerebral hemispheres
Corpus Callosum - answer✔band of white matter connecting hemispheres
Frontal, Parietal, Occipital, Temporal - answer✔lobes of the cerebrum
Central Sulcus - answer✔separates frontal lobe from parietal lobe
Precentral Gyrus - answer✔located immediately anterior to the central sulcus, and contains the
primary motor cortex, somatopically organized
Postcentral Gyrus - answer✔located immediately posterior to the central sulcus, and contains the
primary somatosensory cortex
Lateral Fissure - answer✔separates frontal lobe from temporal lobe
Parieto-occipital Sulcus - answer✔separates parietal lobe from occipital lobe

Forebrain, Midbrain, Hindbrain - answer✔three parts of the brain
Primary Auditory Cortex - answer✔located at the temporal lobe, mapped at a tonotopic fashion,
arranged from low tones to high tones
Wernicke's Area - answer✔located at the temporal lobe, area associated with the
interpretation/understanding of speech, secondary auditory cortex
Broca's Area - answer✔located at the frontal lobe's planning area, area associated with the
formulation of speech and the movement of lips
Arcuate Fasciculus - answer✔connects Wernicke's Area (interpretation) and Broca's Area
(formation)
Supramarginal Gyrus - answer✔located at the parietal lobe, area involved with reading and fine
motor-control of eyes for reading
Angular Gyrus - answer✔located at the parietal lobe, area involved with writing and fine motor-
control of hands for writing
Frontal Association Cortex - answer✔frontal lobe area involved with intelligence, personality,
behavior, mood, and cognitive function
Parietal Association Cortex - answer✔parietal lobe area involved with spatial skills and 3D
shapes, including faces, concepts, and abstract perception
