• mid-brain and pons.

mid-brain and pons

• Pons means bridge.
• The mid-brain is the highest on the brain
• stem.
• It is involved in motor control and sensory
  analysis.
• It controls many automatic functions.
• It sifts millions of signals sent to the brain
  every second from the rest of your body.

• cerebellum

5

• Cerebrum

6

• The brainstem

7

• The midbrain is the highest point on the
• brainstem and helps our eyes adjust to light
  and our ears to hear sound.
• The brainstem is about 3 inches long,
• and has 3 parts, the midbrain, the pons, and
  the medulla.

8

• Pons or bridge sends messages between thbrain
  and the spinal cord to tell us when to wale k.
• The brainstem is also known as the reptilian
  brain, because it is the oldest
• thinking part of the brain.

9

• The medulla is in the top of the spine and
  controls all the automatic functions of our body
  like heartbeat, digestion, breathing, swallowing
  and blood pressure.

10

• The Limbic System

11

• Lobes and cranium

12
The Cranium

• Your brain

13
Frontal lobe

• Located in front of the central sulcus.
• Damage can result mood changes.

14
Parietal lobe

• Located behind the central sulcus.

15
Temporal lobe

• The temporal lobe is important to the
• Senses of smell and sounds.

16
Occipital lobe

• Concerned with many aspects of visions.

17
The Cranium

• At birth the cranium is not fully formed.
• Your brain continues to grow until you are seven
  years old.
• Your skull is made up of twenty/eight bones.

18

• Thalamus

19

• The Thalamus is the first stop for sensory
  messages.
• Sensory messages are pain,pressure, and
  temperature.

20

• The Thalamus knows that you are getting hurt but
  does not know where the pain is coming from!

21

• For example,if you put your hand over a flame,the
  message goes from the thalamus to the cerebral
  cortex down the spinal cord and tells the hand to
  move.

22

• Thalamus means inner room in Latin. Your
  Thalamus is located in the middle of tour brain
  and looks like an egg.

23

• If you spilt the brain in half both the left and
  right hemispheres would each get a half of the
  thalamus.

24

• The thalamus regulates sleep cycles and
  wakefulness.
• It also seems to help you feel if you are in a
  good mood or a bad mood.

25

• The Hypothalamus

26

• The Medulla Oblongata

27
Medulla Oblongata

• The Medulla Oblongata is approximately. 3 cm
  Long.
• The Medulla Oblongata houses nerve
• Centers that control breathing, heart rate,
• Blood pressure, swallowing, and other
• Important functions.

28
Medulla Oblongata

• The Medulla is one of four major parts
• Of the brainstem.
• The Medulla contains nerve cells that
• Go up, and nerve cells that go down.
• The Medulla is at the lowest part of
• The brainstem.

29
Size of the Hypothalamus

• The Hypothalamus is slightly larger than a red
  kidney bean.
• It weighs -1/300of the whole brain (4 grams).
• It can do more per unit weight than any other
  part of the brain.

30
Location of the Hypothalamus

• The Hypothalamus(hypo-under and thalamus-inner
  room) is located between the two cerebral
  hemispheres-diencephalaons.
• It is the inferior portion of the diencephalons.

31
Controls and prepares you to handle emotions

• Limbic system-a group of structures deep in the
  fore brain involved with emotional behavior.
• Controls and prepares you to handle emotions such
  as hunger,thirst,fear and happiness.
• Controls the level of alertness such as sleeping
  and waking.

32
Monitoring the blood

• The Hypothalamus is on a 24 hour blood alert.
• It constantly monitors the blood to make sure it
  has everything it needs.
• It is directly responsible for innate biological
  drives most fundamental to survival.

33
Hunger pangs

• You get energy from food.
• Food breaks down into sugar and blood carries it
  to different parts of the body

34
Water works and waste

• It is important to have the right amount of water
  in the blood.
• Kidneys act as filters.

35
Maintains the body temperature

• It helps keep your body temperature at about 98.6
  F even if it is cold or hot outside.
• When your body becomes overheated the
  Hypothalamus stimulates your sweat glands to
  produce perspiration which comes through the
  pores that evaporates to cool your skin.

36
Oxygen uptake

• All parts of your body need oxygen.
• Blood carries oxygen all over the body.
• You need more oxygen than usual when you work
  hard like running up a steep hill.

37
Functions of the hypothalamus

• The hypothalamus is the most fascinating area of
  the brain.
• brain within the brain.
• It is a important central monitor for many
  functions.

38
The hormonal and Nervous system

• Controls the pituitary or master gland.
• It is the link between two major systems of the
  body -brain and nerves and the hormonal or
  endocrine system.

39
Cerebral CortexBy Duncan Raynor
40

• The gyri are the parts of the cerebral cortex you
  see on a brain and the sulci are the parts of the
  cerebral cortex that are folded under the gyri.

41

• The cerebral cortex is like the main control
  center of thinking, learning, remembering and
  planning.

42

• The cortex, which means bark, covers the brain
  like bark might cover a tree.

43

• There are about 50 billion nerve cells in the
  cerebral cortex.

44

• The cerebral cortex is not very colorful. It is
  made up of mostly pinkish-gray nerve cells.
