Cerebrum
21
- Two hemispheres (right and
left)departed by longitudinal fissure.
- Major lobes are named after
overlapping lobes:
CEREBRUM
21
- for Equilibrium and Balance
Cerebellum
22
Major Lobes:
1. Frontal
2. Temporal

FOUR VENTRICLES
- CSF filled chambers
- Communicating with central canal of
spinal cord
- Where CSF circulates
- Lined by ependymal cells
1. Lateral Ventricle (2)
2. 3rd Ventricle
3. 4th Ventricle
29
Formation in ventricles by
specialized ependymal cells of
chorid plexuses (500ml /aday)
(150mL)

33
CORPORA QUADRIGEMINA
- Two pairs of sensory nuclei
1. Superior colliculi (visual)
2. Inferior Colliculi (auditory)
33
- Have functional regions
- Motor, sensory, and association
- Received information and generate
commands for opposite side of the
body.
CEREBRAL HEMISPHERE
33
- Right side controlled by left
- Left side controlled by right
LATERALIZATION
34
- Regulates motor output
- Should be black in CT, if not black
then there is a problem in movement
