1

The brain is classified into six postembryonic divisions

telencephalon, diencephalon, mesencephalon, pons, medulla oblongata, cerebellum

2

Telencephlaon consists of ____

cerebral hemispheres and the basal nuclei

3

Cerebral hemispheres emcompasses which brain regions

frontal lobe, temporal lobe, parietal lobe and lateral ventricles

4

Cerebral hemispheres are separated by which structures

the longitudinal cerebral fissure and the falx cerebri

5

Cerebral hemispheres are interconnected by which structure

corpus callosum

6

Frontal lob extends from ___ to ____

central sulcus, frontal lobe

7

Gyri of the frontal lobe

superior frontal gyrus, middle frontal gyrus, inferior frontal gyrus, gyrus rectus and orbital gyri, anterior paracentral lobule

8

Superior frontal gyrus (describe)

supplementary motor cortex on the medial surface (area 6)

9

Middle frontal gyrus (describe)

contains the frontal eye field (area 8)

10

Inferior frontal gyrus (describe)

contains the Broca speech area in the dominant hemisphere (areas 44 and 45)

11

Gyrus rectus and orbital gyri (describe)

separated by the olfactory sulcus

12

Anterior paracentral lobule (describe)

Found on the medial surface between the superior frontal gyrus and the central sulcus

13

Parietal lobe (location)

extends from the central sulcus to the occiptal lobe. Lies superior to the temporal lobe.

14

Gyri of the parietal lobe

postcentral gyrus, superior parietal lobule, inferior parietal lobule, precuneus, posterior paracentral lobule

15

Postcentral gyrus (describe)

the primary somatosensory area of the cerebral cortex (areas 3, 1, and 2)

16

Superior parietal lobule (describe)

comprises association areas involved in somatosensory functions (areas 5 and 7)

17

Gyri of inferior parietal lobule

supramarginal gyrus, angular gyrus

18

Supramarginal gyrus (describe)

interrelates somatosensory, auditory, and visual inputs (area 40)

19

Angular gyrus (describe)

receives impulses from primary visual cortex (area 39)

20

Precuneus (describe)

located between the paracentral lobule and the cuneus
