Unit 2 Part 2

Question 1

Old Brain (Reptilian Brain)

Answer 1

Brainstem, Thalamus, Cerebellum, Reticular Formation

Question 2

Brainstem

Answer 2

1. Brainstem
2. Pons
3. Medulla Oblongata
   - All are the 1st part of the brain formed in the womb, it connects the brain to the spinal cord
   - It’s job is to keep you alive by doing auto survival functions (breathing, heartbeat, swallow, body temp, etc.)

Question 3

Reticular Formation

Answer 3

Controls Arousal (Awakeness/Alertness)

Question 4

Thalamus

Answer 4

How the brain communicates with itself

Question 5

Cerebellum (Little brain)

Answer 5

In charge of muscle memory. (walking, eating, etc)

Question 6

Limbic System

Answer 6

Amygdala, Hypothalamus, Hippocampus, Pituitary Gland

Question 7

Amygdala

Answer 7

In charge of the fight or flight response
- Controls the emotions of fear and aggression

Question 8

Hippocampus

Answer 8

Processes short term memory into long term memory

Question 9

Hypothalamus

Answer 9

In charge of the emotion of reward and basic maintenance functions (eating, drinking, regulating body temp.)
- Brain of the endocrine system

Question 10

Ventromedial Hypothalamus

Answer 10

Controls hunger

Question 11

Pituitary Gland

Answer 11

Hypothalamus uses the PG in order to communicate with other glands of the endocrine system
- Helps with physical growth (often at night)

Question 12

Cerebral Cortex

Answer 12

• Most advanced region of the brain
  4 Regions
• Occipital, Temporal, Parietal, Frontal

Question 13

Occipital

Answer 13

Process our vision

Question 14

Temporal

Answer 14

Process our hearing

Question 15

Parietal

Answer 15

Process sense of touch

Question 16

Frontal

Answer 16

2. Emotion control
3. Planning and judgement

Question 17

Brain isn’t done forming till age?

Answer 17

age 25

Question 18

Motor Functions

Answer 18

Motor Cortex, Somatosensory Cortex

Question 19

Motor Cortex

Answer 19

• Region of the brain that controls the motor function of specific ares of the body.

Question 20

Somatosensory Cortex

Answer 20

Region of the brain that controls the sense of touch in specific areas of the body

Question 21

Association Functions

Answer 21

small areas of the brain that have specific high-functioning tasks
- Broca’s Area
- Wernicke’s Area

Question 22

Broca’s Area

Answer 22

• Can write
• in the left hemisphere frontal lobe
• In charge of the fine motor movement of mouth while speaking.

Question 23

Wernicke’s Area

Answer 23

• cannot write
• left hemisphere of the brain in the temporal lobe
• in charge of language expression and language understanding

Question 24

Corpus Collasum

Answer 24

Band of neural fibers that commands the 2 hemispheres of the brain
- left side of brain = right side controlled vice-versa

Question 25

Plasticity

Answer 25

- Brain can change shape to create new neural connections to replace what was lost
