1

Frontal Lobe

Part of Cerebrum 

  1. Motor control (voluntary motor skills)
  2. Motor speech
  3. Concentration, planning, & problem solving
  4. "Thinking" 

2

Parietal Lobe

Cerebrum 

  1. Somato-sensory cortex = feeling/touch 
    1. "Feeling" your body
  2. Understanding speech & using words

3

Occipital Lobe

Cerebrum

  1. Visual cortex = vision
  2. Process of "seeing" an image

4

Temporal Lobe

Cerebrum

  1. Hearing (pitches)
  2. Recognizing auditory patterns ("what am I hearing?")
  3. Memories

5

Cerebellum

  • Function: balance, coordination, & motor control
  • "The bell of the ball loves to dance" 

6

The brain stem is composed of what parts?

  1. Medulla oblongata
  2. Pons

7

What are the two parts of the medulla oblongata?

  1. Life support
  2. Decussation of pyramids 

8

The life support function of the brain is found where? 

Medulla oblongata in the brain stem

9

The decussation of pyramids is found where in the brain?

Medulla oblongata in the brain stem

10

The pons is found where on the brain?

The brain stem 

11

The medulla oblongata is found __________ the pons

Below

12

What is the function of the life support function of the medulla oblongata?

Life Support

  • Breathing
  • Heart rate
  • Heart beat
  • Vomitting
  • Coughing

13

What is the function of the decussation of pyramids of the medulla oblongata?

Decussation of Pyramids

  • Cross over nerve tracts
    • Right side of the brain crosses over to the left side of the body
    • Left side of the brain crosses over to the right side of the body 

14

What is the pons?

Pons = "bridge"

  • The pons is a bridge from the lower brain (brain stem) to the upper brain (the higher brain)

15

What are the two functions of the pons?

  1. Bridge between the brain stem (lower brain) and upper brain (higher brain)
  2. Regulates breathing
    1. The pons tells the body how fast, slow, deep, shallow your breathing should be 
    2. More complex breathng 

16

What is another name for the midbrain?

Mesencephalon

17

What is another name for mesencephalan?

Midbrain

18

What are the components of the mesencephalan?

Mesencephalan

  1. Corpora quadrigemina
  2. Cerebral aqueduct
  3. Cerebral pedunc;e

19

What are the components of the midbrain?

Midbrain

  1. Corpora quadrigemina
  2. Cerebral aqueduct
  3. Cerebral peduncle

20

What is the function of the corpora quadrigemina

Corpora Quadrigemina

  1. Involuntary eye reflexes
    1. Dilating and constricting pupils
    2. Blinking
  2. Involuntary ear reflexes
    1. Ringing and muffles
    2. Turning ear to sound (turning and listening) 

21

What is the function of the cerebral aqueduct?

Cerebral aqueduct

  • The function of the cerebral aqueduct is to move/drain cerebrospinal fluid out of the brain 

22

What is the function of the cerebral peduncles?

Cerebral Peduncles

  • Peduncle = tracts (nerve bundles/ fibers)
  • The cerebral peduncle connects the lower brain to the higher brain
    • Carries information from the lower to higher parts of the brain 

23

What is the function of the cerebellum?

Cerebellum

  • Balance, coordination, and motor control
  • "The bell of the ball wants to dance" 

24

What part of the brain is considered the "second brain"

Diencephalon

25

What are the components of the diencephalon?

Diencephalon

  1. Thalamas
  2. Hypothalamus
  3. Epithalamus 

26

What part of the diencephalon is considered the "second brain"?

Thalamus

27

What is the function of the thalamus?

Thalamus

  • "Telephone operator"
  1. Sorter/switchboard/ brain's router
    1. Projection = to send the signal to different places
  2. Senses pain and temperature

28

What is the function of the hypothalamus?

Hypothalamus

  1. Homeostasis
    1. Negative & positive feedback
  2. Drives
    1. Hunger, thirst, sex

29

What is the function of the epithalamus?

Epithalamus?

  1. Contains the pineal body/gland
    1. ​Pineal gland makes the hormone melatonin
  2. Contains choroid plexus
    1. Choroid plexus makes CSF (cerebrospinal fluid) with ependymal cells
    2. Four choroid plexi

30

Diencephalon (second brain) in the epithalamus
