3. 1. Cerebrum
oDivided into two hemispheres
oRight – creative, big picture
oLeft – logical, mathematical
oRight side of brain controls the
left side of the body
oLeft side of the brain controls
the right side of the body
7. oCerebrum consist of both gray
matter and white matter
oGray matter on the outside
called cerebral cortex
o and white matter on the inside

8. Note: Brain is convoluted or
folded to get more in a tight
space.
So well designed equivalent all
phone cable of world into a
thimble – WOW!
9.
10. Four division or pairs of lobes of
the cerebrum
Frontal lobes (right and left)
Parietal lobes (right and left)
Occipital lobes (right and left)
Temporal lobe (right and left)
11.
12. Frontal lobe:
location of personality, judgment
and self control
Motor area of frontal lobe – part
of frontal lobe in the rear portion
controls the voluntary movement
of the skeletal muscles.
15. Occipital lobe: sense of vision
Temporal lobes: sense of hearing,
smell and taste, also long term
memory
16. Three Major Parts of the Brain
1. Cerebrum
2. Cerebellum
second largest brain region;
means little brain
right and left hemispheres
white and gray matter
tightly packed, convoluted
17.
18. 2. Cerebellum
Function:
To take over the skeletal muscle
control from the cerebrum so it
is free to think about biology!
Cerebrum slowly gives up as
practice (ex. Basketball layup,
bike riding)
19. Three Major Parts of the Brain
1. Cerebrum
2. Cerebellum
3. Brain stem
located between
cerebrum and spinal cord
20.
21. 3 parts to brain stem:
a. medulla oblongata
• lowest section of brain stem
•regulates breathing, blood
pressure, and other vital functions
•crossover occurs in medulla
oblongate
22.
23.
24. 3 parts to brain stem:
a. medulla oblongata
b. Pons
links cerebrum and
cerebellum
assist medulla in regulating
breathing
coordinates eye movement
25.
26. 3 parts to brain stem:
a. medulla oblongata
b. Pons
c. Midbrain
located above the pons
coordinates eye movements
and pupil dilation
contains reticular formation
27.
28. Reticular Formation:
On/off switch of cerebrum
Switches cerebral cortex on you
wake and are conscious/off you go
to sleep, adjust level of alertness
Damage = coma
30. Limbic System
a number of complex
brain structures
around the brain stem.
31. Limbic system includes:
thalamus – switch board –
sends pulses to right place in
brain
hypothalamus – control unit
for autonomic and endocrine
systems (adrenaline)
