Ch2 Part 2

Question 0

Medulla

Answer 0

Base of brain stem, controls heartbeat and breathing

Question 1

Brain stem

Answer 1

Oldest part and most central point of the brain, begins where the spinal chord enters the skull, automatic survival functions

Question 2

Reticular formation

Answer 2

Nerve network in the brain stem, plays a role in arousal

Question 3

Thalamus

Answer 3

Sensory switchboard, top of brain stem, relays all senses except smell

Question 4

Hippocampus

Answer 4

Processes memory

Question 5

Pons

Answer 5

Helps coordinate movement, (ask mrs Lund before quiz)

Question 6

Cerebellum

Answer 6

Attached to the rear of the brain stem, coordinates movement and balance

Question 7

Limbic system

Answer 7

Doughnut-shaped system of neural structures between the brainstem and the central hemispheres, (hippocampus, pituitary gland, amygdala, hypothalamus)

Question 8

Amygdala

Answer 8

Two bean-sized neural structures that are linked to emotion aggression and fear

Question 9

Hypothamus

Answer 9

Below the thalamus, directs maintenance activities (drinking, eating, body temp) governs endocrine system via the pituitary gland, also linked to emotion

Question 10

Cerebral cortex

Answer 10

The bark of the brain, covers the hemispheres, ultimate control and processing center

Question 11

Glial cells

Answer 11

Support, nourish, and protect neurons

Question 12

Frontal lobes

Answer 12

Just behind the forehead, used for speaking, muscle movements, planning, and judgement

Question 13

Occipital lobes

Answer 13

Back of the head, visual areas, receives info from the opposite visual field

Question 14

Parietal lobes

Answer 14

Top of head and towards the rear, receives sensory input for touch and body position

Question 15

Temporal lobes

Answer 15

Above the ears, auditory areas, primarily receives info from the opposite ear.

Question 16

Motor cortex

Answer 16

Rear of the frontal lobes, controls voluntary movement

Question 17

Sensory cortex

Answer 17

Part of the parietal cortex, receives info from sense organs

Question 18

Association areas

Answer 18

Gray matter of the brain, in the cortex, involved in higher level thinking, more advanced animals have more

Question 19

Phineus gage

Answer 19

A railroad worker who had his frontal lobes damaged, this severely changed his personality for the worse

Question 20

Aphasia

Answer 20

Impairment of communicating or understanding through language due to damage in the Broca’s or Wernicke’s area

Question 21

Broca’s area

Answer 21

Controls speech via the motor cortex, left frontal hemisphere
(Broca’s area = broken speech)

Question 22

Wernicke’s area

Answer 22

Interoperates auditory tone, temporal left hemisphere

Question 23

Plasticity

Answer 23

The brain’s ability to repair or modify itself in response to an injury or damage, more effective in younger people

Question 24

Corpus callosum

Answer 24

A large band of neural fibers that connect the brain’s two hemispheres

Question 25

Split brain

Answer 25

The brain’s hemispheres are isolated by cutting the connecting fibers between them
