Cererbrum into

Question 1

The cerebrum is derived embryologically from?

Answer 1

The telencephalon

Question 2

Answer 2

largest part of the forebrain which reaches the greatest degree of development in the human brain

Question 3

The cerebral cortex is located ________

Answer 3

superficially

Question 4

The cerebral cortex is located superficially and consists of

Answer 4

cortical grey matter (i.e. nerve cell bodies) that is highly convoluted to form a complex pattern of ridges (gyri; singular, gyrus) and furrows (sulci; singular, sulcus)

Question 5

The subcortical grey matter is located within the

Answer 5

White matter

Question 6

The subcortical grey matter is located within the white matter and consists of the

Answer 6

thalamus and basal ganglia

Question 7

The cerebral white matter is located deep to the cortex and consists of

Answer 7

nerve fibers (axons)

Question 8

Most of the nerve fibres running between the cortex and subcortical structures are condensed, deep within the hemisphere, into a

Answer 8

broad sheet, the internal capsule

Question 9

Between the internal capsule and the cortical surface, fibres radiate in and out, to produce a

Answer 9

fan-like arrangement, the corona radiata

Question 10

The cerebrum houses the _________ ventricles

Answer 10

Lateral ventricles

Question 11

Two hemispheres are separated by the

Answer 11

longitudinal fissure

Question 12

Corpus callosum is located in the depths of the fissure and is an enormous sheet of commissural nerve fibres which run between corresponding areas of the two cortices

Question 13

Name the three surfaces of the cortex

Answer 13

1. Superolateral
2. Medial
3. Inferior

Question 14

2. Inferolateral
3. Inferomedial

Question 15

Question 16

Name the lobes

Answer 16

Question 17

Question 18

The lateral fissure:

Answer 18

Separates the temporal lope from the frontal and parietal lobes

Question 19

What is found deep to the lateral fissure

Answer 19

The insula

Question 20

The parts of the frontal, parietal and temporal lobes overlying the insula

Answer 20

= the operculum

Question 21

A single, uninterrupted sulcus that extends from the medial longitudinal fissure (superiorly) to the lateral fissure (inferiorly)

Answer 21

= central sulcus

Question 22

The central sulcus also extends (for a very short distance) onto the medial surface of the hemispheres – within the longitudinal fissure

Question 23

What is found within the precentral gyrus

Answer 23

Primary motor region of the cortex

Question 24

What is found in the postcentral gyrus

Answer 24

primary somatosensory cortex

Question 25

Intraparietal sulcus divides the parietal lobe into

Answer 25

a superior and inferior parietal lobule

Question 26

What is located within the superior temporal gyrus

Answer 26

The primary auditory cortex

Question 27

Question 28

Location of the primary visual cortex

Answer 28

Calcarine sulcus

Question 29

Cingulate sulcus course and location

Answer 29

curves around the corpus callosum and runs parallel to it It passes posteriorly and inferiorly around the posterior surface of splenium of the corpus callosum, it then becomes continuous with the parahippocampal gyrus

Question 30

Parahippocampal sulcus location

Answer 30

lies deep to the parahippocampal gyrus within the temporal lobe

Question 31

The parahippocampal sulcus is formed by

Answer 31

the in-curling of the inferior medial part of the temporal lobe

Question 32

The limbic lobe consists of the

Answer 32

Cingulate gyrus parahippocampal gyrus hippocampus

Question 33

The insula lies deep to the

Answer 34

lateral fissure

Heschl’s convolutions indicate the

Answer 35

functional localization of the primary auditory cortex
