MEDICAL NEUROSCIENCE- WEEK 2,
LESSON 1: CEREBRAL CORTEX,
BRAINSTEM, AND BLOOD SUPPLY
EXAM QUESTIONS AND ANSWERS
Parieto-occipital sulcus - Answer-medial boundary between parietal and occipital
lobes.
Lateral occipital gyri - Answer-Gyral structures posterior to lateral boundary between
parietal and occipital lobes.
Insula - Answer-Region of cortex hidden beneath the frontal, temporal, and parietal
lobes that is part of the continuous sheet of cortex and slower growing. Concerned
with visceral, autonomic, and taste functions. Integrate brain functions the impact
emotion and social cognition.
Cerebral Hemispheres - Answer-Especially large in humans. Covered by cerebral
cortex. Highly infolded surface.
Lateral Aspect View - Answer-Can see: Cerebral Hemispheres, Cerebellum, and
Brainstem
Cerebral Cortex - Answer-2-3 mm thick layer of cells and cellular processes that
cover the cerebral hemispheres. The surface area of this unfolded and flattened is
about equal to 13-inch pizza
Gyri (gyrus) - Answer-The ridges formed by the infoldings of the brain.
Sulci (sulcus) - Answer-The valleys formed by the infoldings of the brain
Fissures - Answer-Especially deep valleys in the brain.
The lobes - Answer-The hemispheres are divided into the frontal, parietal, occipital,
and temporal lobes
Frontal Lobe - Answer-Most anterior lobe of the lobes.
Parietal Lobe - Answer-Between Frontal and Occipital lobes and superior to temporal
lobe.
Occipital Lobe - Answer-The most posterior lobe.
Temporal Lobe - Answer-Major lobe in brain that is inferior to Frontal and Parietal
lobes and anterior to Occipital lobe. Functions include visual and emotional
processing, memory, and integration of sensory experience.
