The forebrain

Question 1

The FB consists of the

Answer 1

Diencephalon and the cerebrum

Question 2

The diencephalon consists of

Answer 2

Dorsal thalamus
Ventral thalamus

Question 3

Dorsal thalamus

Answer 3

Large egg-shape mass of grey matter on either side of the third ventricle

Question 4

The anterior end of the thalamus forms the posterior boundary of the

Answer 4

interventricular foramen

Question 5

Hypothalamus forms the lower part of the

Answer 5

lateral wall of the 3rd ventricle

Question 6

Question 7

What is the largest part of the brain?

Answer 7

The cerebrum

Question 8

The two cerebral hemispheres are connected by the

Answer 8

the corpus callosum
(white matter)

Question 9

The cerebrum extends from

Answer 9

frontal to occipital bones of the skull, superior to the anterior and middle
cranial fossae

Question 10

The cerebrum is located

Answer 10

above the tentorium cerebelli
posteriorly

Question 11

The two cerebral hemispheres are separated by a deep cleft…

Answer 11

longitudinal fissure

Question 12

Question 13

What projects into the longitudinal fissure?

Answer 13

Falx cerebri

Question 14

Falx cerebri and tentorium cerebelli are dural reflections
These are produced when the inner layer of the dura mater fold onto itself and projects into the cranial cavity, and in doing so, incompletely divides the cranial cavity into several compartments that house different parts of the brain

Question 15

The surface layer of each cerebral hemisphere =

Answer 15

cortex

Question 16

The outer surface of the cerebrum is composed of white/gray matter?

Answer 16

Gray matter

Question 17

The cortex is highly folded.
What is the purpose of this?

Answer 17

Increases the surface area of the cortex

Question 18

Gyri (singular: gyrus)

Answer 18

= folds

Question 19

Sulci (singular: sulcus)

Answer 19

= grooves located between the gyri

Question 20

Fissures

Answer 20

= deep sulci

Question 21

Large sulci (fissures) subdivide the surface of each hemisphere into

Answer 21

lobes

Question 22

Lobes of the brain are names according to

Answer 22

bones of the cranium under which they lie

Question 23

Question 24

Below the cortex, each hemisphere of the cerebrum contains a central core of

Answer 24

White matter

Question 25

basal nuclei (ganglia)

Answer 25

Several large masses of gray matter which are located within the white matter

Question 26

Corona radiata is a

Answer 26

Fan-shaped collection of nerve fibres (found within the cerebrum)

Question 27

The corona radiata runs in the

Answer 27

white matter to and from the cortex to the brainstem

Question 28

The corona radiata converges on the

Answer 28

the basal nuclei and pass between them as the internal capsule

Question 29

The caudate nucleus (of the cerebrum) is found

Answer 29

Medial to the internal capsule

Question 30

The lentiform nucleus (of the cerebrum) is found

Answer 30

lateral to internal capsule

Question 31

Lentiform nucleus consists of

Answer 31

globus pallidus + putamen

Question 32

The lateral ventricle of the cerebrum is a

Answer 32

CSF filled cavity located within each hemisphere

Question 33

The lateral ventricle of the cerebrum communicates with the

Answer 33

3rd ventricle via the interventricular
foramina

Question 34
