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
