1

What kind of fibres pass through the corpus callosum

Commmisural fibres

2

Describe the septum pellucidum

A thin sheet which lies in the mid sagittal plane and separates the anterior horns of the 2 lateral ventricles

3

What surrounds the septum pellucisum

Corpus callosum and Fornix

4

What is the Fornix

Bundle of fibres which links the hippocampus with the mammillary bodies of the hypothalamus

5

List some of the functions of the hypothalamus

Homeostasis
Endocrine control
Autonomic control
Limbic functions
Sexual behaviour
Regulating body temperature

6

What dural fold overlies the pituitary gland

diaphragma sellae- dura mater

7

Where are the colliculi in relation to the pineal gland

Inferior to pineal gland

8

Name some features seen in a transverse section of the brain

Median longitudinal fissure
Anterior horn of lateral ventricle
Caudate nucleus
Lentiform nucleus (putamen and globus pallidus)
Thalamus
Tail of caudate nucleus
Posterior horn of lateral ventricle
Third ventricle

9

What structures together constitute the basal ganglia (nuclei)

Lentiform nucleus
Caudate nucleus

10

What is the name given to the fibres that connect the cerebral hemispheres with other parts of the brain

Projection fibres

11

Which cerebral artery through one of its branches supplies the internal capsule

Middle cerebral artery

12

Identify a distinctive feature of the midbrain

Substantia nigra

13

Which group of structures is the substantia migrant a part of

Basal ganglia

14

Where would the red nucleus be in relation to the substantial nigra

Anterior to it

15

What fibres do the cerebral peduncles contain

Large ascending (sensory) and descending (motor) nerve tracts from cerebrum to pons

16

Which part of the pons would motor fibres and sensory fibres from the medial lemniscus occupy

Ventral

17

What fibres make up the pyramid and olive in the medulla

Inferior olivary nucleus on the ventral surface

18

Features of cervical spinal cord

Large white matter
Small grey matter
Long slender posterior horn
Broad massive anterior horn

19

Features of thoracic spinal cord

Large white matter
Small grey matter
Lateral horn
Slender posterior horn and anterior horn

20

Features of lumbar spinal cord

White matter is larger than cervical and thoracic.
Bulbous and short anterior and posterior horn

21

features of sacral spinal cord

White matter less than grey matter
Massive and ovoid posterior horn and anterior horn

22

Which aspect of the spinal cord receives sensory nerve fibres

Dorsal horn

23

From which aspect of the spinal cord do motor nerve fibres project

Ventral root

24

Why does size of the ventral grey horn vary along the spinal cord

Ascending tracts gain fibres at each succession level and the opposite happens for descending.
High levels contain greater amounts of white matter

25

What is the nae of the hole in the middle of the spinal cord an what does it contain

Central canal
CSF
