,gyri (singular gyrus) Answer: elevated folds of gray matter in the cerebral cortex
Sulci (sulcus) Answer: shallow grooves
Fissures Answer: deep grooves
cerebral hemispheres Answer: the two sections of the cortex on the left and right sides of the
brain
longitudinal fissure Answer: separates cerebral hemispheres
central sulcus (separates which lobes) Answer: frontal from parietal (goes uninterrupted across
the top of the brain)
pre-central gyrus Answer: primary motor cortex
post central gyrus Answer: primary sensory cortex
Parietal lobes Answer: portion of the cerebral cortex lying at the top of the head and toward the
rear; receives sensory input for touch and body position (yellow/B in the diagram)
Temporal lobes Answer: portion of the cerebral cortex lying roughly above the ears; includes
the auditory areas, each receiving information primarily from the opposite ear
occipital lobe Answer: visual processing
Lateral fissures (same as lateral sulcus) Answer: separates temporal lobe from frontal and
parietal lobes
Cerebral cortex Answer: gray matter (superficial)
white matter Answer: Made of axions that connect gray matter (deep)
corpus callosum Answer: the large band of neural fibers connecting the two brain hemispheres
and carrying messages between them
parieto-occipital sulcus Answer: separates parietal and occipital lobes
