Flashcards in Ch 2.5 Deck (26):
0

Brain stem

Oldest part, begins where spinal cord swells and enters skull, automatic survival functions

1

Medulla

Base of brain stem controls heart beat and breathing

2

Reticular formation

Controls arousal and awareness

3

Thalamus

Sensory switchboard, directs messages to sensory areas an transmits replies, not sense of smell

4

Hippocampus

Processes memory

5

Pons

Coordinates movement

6

Cerebellum

"Little brain" rear of brain stem, coordinates voluntary movements and balance

7

Limbic system

System of neural structures associated with emotions
Hippocampus, amygdala, pit. gland, hypothalamus

8

Amygdala

Linked to emotions, aggression and anger

9

Hypothalamus

Directs maintenance activities, helps govern pit gland

10

Cerebral cortex

Covers cerebral hemisphere, body's ultimate control and info processing center

11

Glial cells

"Glue cells" that guide neural connections, provide nutrients and insulating myelin

12

Frontal lobes

Forehead

13

Occipital lobes

Back head

14

Parietal lobes

Top rear head

15

Temporal lobes

Side if head, above ears, near temples

16

Motor cortex

Area at rear of frontal lobes control voluntary movements

17

Sensory cortex

(Parietal cortex) receives info from skin surface and sense organs

18

Association areas

Makes us higher than rats, cats, and gorillas

19

Phineas Gage

Railroad worker, accidentally shot rod through left cheek and out of top of skull, frontal lobe severely damaged, personality different, "no longer Gage"

20

Aphasia

Impairment of language

21

Broca's area

Frontal lobe speaking, left hemisphere, if damaged broken speech

22

Wernickes area

Understanding info, temporal lobe, left hemisphere

23

Plasticity

Refers to brains ability to modify itself after some type of injury or illness

24

Corpus callosum

The large band of neural fibers connecting the two brain hemispheres and carrying messages between them

25

Split brain

A condition in which the two hemispheres of the brain are isolated by cutting the connecting fibers (mainly those of the corpus callosum) between them
