In This Section

1. What are the four major externally visible lobes of each cerebral hemisphere?

The frontal, parietal, temporal, and occipital lobes.

2. Which additional cerebral lobe lies deep within the lateral sulcus?

The insular lobe, also called the insula.

3. Which functional and anatomical region is sometimes described as the limbic lobe?

A ring of medial cortical structures, particularly the cingulate and parahippocampal gyri.

4. Which major sulcus separates the frontal lobe from the parietal lobe?

The central sulcus, also called the sulcus of Rolando.

5. Which major sulcus separates the temporal lobe from the frontal and parietal lobes?

The lateral sulcus, also called the Sylvian fissure.

6. Which sulcus marks the medial boundary between the parietal and occipital lobes?

The parieto-occipital sulcus.

7. Which imaginary line helps define the occipital lobe on the lateral cerebral surface?

A line connecting the parieto-occipital sulcus to the preoccipital notch.

8. Where is the frontal lobe located?

Anterior to the central sulcus and superior to the lateral sulcus.

9. Which gyrus contains the primary motor cortex?

The precentral gyrus of the frontal lobe.

10. Which Brodmann area corresponds primarily to the primary motor cortex?

Brodmann area 4.

11. Which frontal lobe region is primarily involved in planning, judgment, and executive functions?

The prefrontal cortex.

12. Where is Broca's area typically located in the language-dominant hemisphere?

The pars opercularis and pars triangularis of the inferior frontal gyrus.

13. Where is the parietal lobe located?

Posterior to the central sulcus, superior to the lateral sulcus, and anterior to the occipital lobe.

14. Which gyrus contains the primary somatosensory cortex?

The postcentral gyrus of the parietal lobe.

15. Which Brodmann areas correspond to the primary somatosensory cortex?

Brodmann areas 3, 1, and 2.

16. Which two gyri form the inferior parietal lobule?

The supramarginal gyrus and angular gyrus.

17. Which medial parietal region is associated with visuospatial processing and internally directed cognition?

The precuneus.

18. Where is the temporal lobe located?

Inferior to the lateral sulcus and anterior to the occipital lobe.

19. Which temporal lobe gyri contain the primary auditory cortex?

The transverse temporal gyri of Heschl.

20. Which medial temporal lobe structure is essential for forming new declarative memories?

The hippocampus.

21. Which temporal lobe structure is strongly associated with emotional processing and fear-related learning?

The amygdala.

22. Which posterior temporal region is traditionally associated with language comprehension?

The posterior superior temporal region of the language-dominant hemisphere, commonly called Wernicke's area.

23. What is the principal sensory function of the occipital lobe?

Processing visual information.

24. Which sulcus is bordered by the primary visual cortex?

The calcarine sulcus on the medial occipital surface.

25. Which Brodmann area corresponds to the primary visual cortex?

Brodmann area 17.

26. Which cortical regions cover the insula?

The frontal, parietal, and temporal opercula.

27. What major functions are associated with the insular cortex?

Interoception, gustatory processing, visceral sensation, and integration of emotional and autonomic information.

28. Which major artery supplies much of the lateral frontal, parietal, and temporal cortices?

The middle cerebral artery.

29. Which major artery supplies much of the medial frontal and parietal cortices?

The anterior cerebral artery.

30. Which major artery supplies most of the primary visual cortex in the occipital lobe?

The posterior cerebral artery.
