1

Sagittal plane

Divide in left and right halve

2

Coronal plane

Divide in front and back

3

Horizontal plane

Divide in upper and lower part

4

Anterior/ Rostral

towards snout

5

Posterior/ Caudal

towards tail

6

Dorsal

towards top of head or Back

7

Ventral

towards bottom of head or Belly

8

Forebrain

telencephalon (cereberal hemispheres)
Diencephalon

9

Telencephalon ( cereberal hemispheres)

Isocortex (neocortex), Basal ganglia, limbic system

10

Diencephalon

Thalamus, Hypothalamus

11

Hindbrain

Metencephalon
Myelencephalon

12

Metencephalon

Crebellum
Pons

13

CNS

Brain + Spinal cord

14

Basal ganglia

Caudate Nucleus + Putamen+ Globus pallidus+
=> involved in motor control, faciliate movement that is required and appropriate & inhibit unwanted behaviour

15

Ventricles

lateral ventricles, third ventricles, cereberal adquaduct, fourth ventricel, central canal

16

Thalamus

Cluster of nuclei, entering point of all sensory information
sends information to the somatosensory cortex and is involved in motor functions

receives information from the basal ganglia and cerebellum and sends it to the motor cortex

17

Hypothalamus

Hypothalamus

18

Cerebellum

Function Motor coordination & Control, integration of sensory and motor functions, learning

19

pons

Motor control and sensory nuclei i.e. cranial nerve nuclei (entry point for information from the ear)

20

medulla

- Transition from brainstem to spinal cord
- Nuclei of cranial nerves XI and XII- control neck & tongue muscles
- End point of reticular formation
- Controls vital functions such as breathing

21

Ventricles/ Ventricular system, fluid filled

- Functions: (1) Shock absorber, (2) Medium for exchange of materials

22

Lateral Ventricles

Extent to all four lobes

23

Gyrus

a ridged or raised portion of a convoluted brain surface

24

Sulcus

a furrow of a convoluted brain surface

25

Sylvian fissure

demarcates the temporal lobe

26

Central sulcus

divides frontal from parietal lobe

27

Precentral gyrus

motor control (map)

28

Postcentral gyrus

touch

29

White matter

a shiny layer underneath the cortex that consists largely of axons with white myelin sheaths

30

Grey matter

areas of the brain that are dominated by cell bodies and do not include myelin
