2. The Human Brain
Chapter 12

3. Parts of the brain The brain consists of 4 main parts: Cerebrum
Cerebellum
Brain stem
diencephalon

4. cerebrum Thalamus* pineal gland Hypothalamus* pituitary cerebellum
Epithalamus*
cerebrum
Thalamus*

cerebellum
pons
medulla
oblongata
spinal
cord
The hypothalamus, thalamus and epithalamus all form the diencephalon

5. Tuesday January 9th
Take out a sheet of paper for notes

6. New page: page 17 Parts of the brain
Cerebrum
Most of the brain mass
Divided into two hemispheres
Right and left hemisphere controls the opposite side
Each hemisphere has 5 lobes
Frontal, parietal, temporal, occipital, insula

7. Parts of the brain Cerebrum (cont) Responsible for
voluntary motor function
Senses
Integration of information

8. Cerebral Lobes
Frontal
Thinking
Creativity
Motor functions

9. Cerebral Lobes
Parietal
Memory
Senses

10. Cerebral Lobes
temporal
Controls:
Hearing
Speech
Memory

11. Cerebral Lobes
Occipital
Vision

12. Cerebral Lobes Insular Not sure of function
Believed to deal with feelings involving pleasure.

16. Open binder/notebook to page 16
Using the post-it/sticky notes for page 16, write questions and a summary for notes on page 17.
If you have an 17A you can use the back of 16A for questions and/or summary.
We will be adding a new page today
Page 19

17. Parts of the brain: Diencephalon
Central core of the forebrain
Consists of three paired structures – thalamus, hypothalamus, and epithalamus

18. Diencephalon
(epithalamus)
Figure 12.12

19. Parts of the diencephalon
Thalamus
Interprets cerebral senses
Involved in memory processing

20. Parts of the diencephalon
Hypothalamus
Integration center of involuntary nervous system (autonomic)
Regulates many processes needed for homeostasis
Regulates hormones (endocrine system)
Controls emotions

21. Parts of the brain The brain stem Composed of: Midbrain Pons
Acts as a relay centers for other brain parts
Controls some reflexes
Causes fear responses
Pons
Connects cerebellum to rest of the brain
Helps to maintain breathing
Continued on next slide

22. Brain stem (Cont) Medulla oblongata Controls many autonomic reflexes
Controls respiratory and heart rates and blood pressure

26. Parts of the brain Cerebellum
Coordinates posture, balance and movement
Some role in learning

27. take out the following:
Brain diagrams
Chapter 12 questions
I will be checking for completion

28. Functional Brain systems
The limbic system
Structures located in the cerebrum, thalamus and hypothalamus
Called the emotional brain
Integrates and responds to wide variety of stimuli that trigger emotions and feelings
Also involved in long term memory processing

29. Protection of the CNS Meninges
Three connective tissues that surrounds the CNS
Functions
Cover and protect CNS
Protect blood vessels
Contains fluid- (cerebrospinal fluid)
Partitions the skull

30. Types of meninges Dura mater Arachnoid mater Pia mater
Outer most, leathery
Arachnoid mater
Middle meninges, forms loose brain covering
Pia mater
Inner most, made of delicate tissue and is highly vascularized

31. Protection of the CNS Cerebrospinal fluid
Fluid found in and around the CNS
Reduces brain weight
Cushions CNS
Protects CNS from trauma
Helps nourish the brain

32. The epidural space Space between the spinal cord and vertebrae
filled with fat and veins
Also filled with cerebrospinal fluid

33. White and Gray matter White matter Gray matter
Nerve fibers with myelin covers
Forms white colored structure of the brain and spinal cord
In brain they form fibers that allow for communication between brain parts
Gray matter
Cell bodies and nerve fibers without myelin
