Regions of brain

Answer 1

1) telencephalon
2) diencephalon
3) brain stem
4) limbic System

Question 2

Language centers

Answer 2

Mostly found in left hemisphere. However prosody are found in right hemisphere

Question 3

Prosody

Answer 3

Allow ability to understand the emotional context of spoken language

Question 4

Diencephalon parts:

Answer 4

Thalamus

Hypothalamus

Pineal gland

Question 5

Thalamus description

Answer 5

Pair of oval masses of gray matter connected by intermediate mass

Question 6

Thalamus function

Answer 6

Directs and processes all incoming sensory impulses except for smell to proper region

Also directs descending/motor impulses to spinal cord

Question 7

Hypothalamus location

Answer 7

Region inferior to thalamus

Question 8

Hypothalamus function

Answer 8

Regulates autonomic nervous system “effectors” or the smooth, cardiac muscle, and gland tissue

Question 9

Hypothalamus controls:

Answer 9

Body temperature
Influences hunger/thirst
Links ANS to pleasure centers
Releases hormones that affect other glands to release hormones

Question 10

Pineal gland description

Answer 10

Small neuroendocrine gland

Question 11

Pineal gland function

Answer 11

Responds to neuron stimulation by releasing hormones that control cyclical behavior

Question 12

Cyclical behavior examples:

Answer 12

In humans, releases melatonin to aid in sleep patterns

Question 13

Brain stem location

Answer 13

Inferior part of brain

Question 14

Regions of brain stem

Answer 14

1) midbrain
2) pons
3) medulla
4) cerebellum

Question 15

Midbrain location

Answer 15

Inferior to hypothalamus

Question 16

Midbrain function

Answer 16

Serves as a connection between brain stem and rest of brain

Question 17

Midbrain nuclei

Answer 17

Controls wakefulness and alertness

Question 18

Pond location

Answer 18

Oval region on anterior side of brain stem

Barely inferior to midbrain

Question 19

Pons function

Answer 19

Serves as a bridge/connection between various brain areas

Question 20

Medulla description and location

Answer 20

About 1 inch long continuation of spinal cord

Inferior to pons

Question 21

Medulla function

Answer 21

Connects major components to ascending and descending tracts

Question 22

Tracts cross from one side of body to the opposite in the brain

Answer 22

Occurs in medulla

Known as decussation of tracts

Question 23

Medulla nuclei

Answer 23

Some keep consciousness
Maintain muscle tone

Control breathing rates and depth

Maintains heart rate (and blood pressure)

Question 24

Cerebellum

Answer 24

2nd largest part of brain in inferior/posterior part of skull

Controls skeletal muscle contractions by making them appropriate

Question 25

Cerebellum components

Answer 25

Made of gray matter

And white matter known as arbor vitae

Question 26

Limbic System

Answer 26

Group of structures scattered throughout the brain

Like the cingulate gyrus

Question 27

Limbic System function

Answer 27

Receive sensations and links them to memories of past experiences
Generates emotions
Routes sense of smell
