1
Q

Regions of brain

A

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

2
Q

Language centers

A

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

3
Q

Prosody

A

Allow ability to understand the emotional context of spoken language

4
Q

Diencephalon parts:

A

Thalamus

Hypothalamus

Pineal gland

5
Q

Thalamus description

A

Pair of oval masses of gray matter connected by intermediate mass

6
Q

Thalamus function

A

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

Also directs descending/motor impulses to spinal cord

7
Q

Hypothalamus location

A

Region inferior to thalamus

8
Q

Hypothalamus function

A

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

9
Q

Hypothalamus controls:

A

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

10
Q

Pineal gland description

A

Small neuroendocrine gland

11
Q

Pineal gland function

A

Responds to neuron stimulation by releasing hormones that control cyclical behavior

12
Q

Cyclical behavior examples:

A

In humans, releases melatonin to aid in sleep patterns

13
Q

Brain stem location

A

Inferior part of brain

14
Q

Regions of brain stem

A

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

15
Q

Midbrain location

A

Inferior to hypothalamus

16
Q

Midbrain function

A

Serves as a connection between brain stem and rest of brain

17
Q

Midbrain nuclei

A

Controls wakefulness and alertness

18
Q

Pond location

A

Oval region on anterior side of brain stem

Barely inferior to midbrain

19
Q

Pons function

A

Serves as a bridge/connection between various brain areas

20
Q

Medulla description and location

A

About 1 inch long continuation of spinal cord

Inferior to pons

21
Q

Medulla function

A

Connects major components to ascending and descending tracts

22
Q

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

A

Occurs in medulla

Known as decussation of tracts

23
Q

Medulla nuclei

A

Some keep consciousness
Maintain muscle tone

Control breathing rates and depth

Maintains heart rate (and blood pressure)

24
Q

Cerebellum

A

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

Controls skeletal muscle contractions by making them appropriate

25
Q

Cerebellum components

A

Made of gray matter

And white matter known as arbor vitae

26
Q

Limbic System

A

Group of structures scattered throughout the brain

Like the cingulate gyrus

27
Q

Limbic System function

A

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