Flashcards in Chapter 2 Part Two Deck (26):
1

Brain Stem

Oldest part of the brain
Automatic and survival functions

2

Medulla

Just above the brain stem
Controls breathing and heartbeat

3

Reticular formation

Controls arousal/alertness

4

Thalamus

Sensory switchboard

5

Hippocampus

Neural center in the limbic system
Storage and memory

6

Pons

Controls sleeping and dreaming(REM)

7

Cerebellum

Processes sensory inputs and coordinates movement and balance

8

Limbic system

Border of brain stem and cerebral hemisphere

9

Amygdala

Part of the limbic center controlling emotions of fear and aggression

10

Hypothalamus

Regulates hunger, thirst, body temp - reward centers

11

Cerebral cortex

Back of the brain

12

Glial cells

Guide neural connections and provides nutrients

13

Frontal lobes

Lobes involved in speaking and muscle movements, planning, and judgement

14

Occipital lobes

Contain visual cortex

15

Parietal lobes

Contains sensory cortex

16

Temporal lobes

Contains auditory areas

17

Motor cortex

Controls voluntary movements

18

Sensory cortex

In front of parietal lobes - behind motor cortex
Registers body touch and processes

19

Association Areas

Connects sensory and motor areas
Thought to be concerned with higher mental activities

20

Phineas Gage

Railroad construction man with severe accident
Had aphasia

21

Aphasia

Important part of language as a result to damage to several cortical areas - Broca's and Weirnickes

22

Broca's area

Located in left frontal lobe
Controlling motor ability to produce speech

23

Weirnickes area

Located in left temporal lobe
Involved in language comprehension and expression

23

Plasticity

Brains capacity for modification after damage to certain parts

24

Corpus Callosum

Large band of neural fibers linking right and left hemisphere allowing them to interact

25

Split Brain

Condition in which corpus Callosum is severed to allow the sides to interact
