17
Q

What are continuously communicating with each other thru the corpus callosum

A

Hemispheres

18
Q

What are the major areas for sensory perception and voluntary motor control in the cortex

A

By their position to the central sulcus

19
Q

What is the part of the sulcus that is anterior to central sulcus and the most posterior part of frontal lobe

A

Pre - central sulcus area

20
Q

What is the part of the sulcus that is posterior to central sulcus and the most anterior part of parietal lobe

A

Post central sulcus area

21
Q

Of the known cerebral functions which one voluntary motor control of the skeletal system muscles

A

Frontal

22
Q

Of the known cerebral functions which one has somatesthethic interpretation; understanding speech and formulating words to express thoughts and emotions

A

Parietal

23
Q

Of the known cerebral functions which one has interpretation of auditory sensations; storage (memory) of auditory and visual experiences

A

Temporal

24
Q

Of the known cerebral functions which one is the integration of movements in focusing the eye; correlation of visual images with previous visual experiences and other sensory stimuli

A

Occipital

25
Q

Of the known cerebral functions which one is memory; sensory (principally pain) and visceral integration is called

A

Insula

26
Q

The strip of cortex that runs medial to lateral and found in both hemispheres. The amount of cortex is based on the number of sensory receptors a specific area the body has

A

Post central sulcus area

27
Q

The strip of cortex that runs medial to lateral and found in both hemispheres. The amount of cortex is based on how much fine control a muscle has

A

Pre-central sulcus

28
Q

What part of the brain coordinates and smoothes out muscle movements. The movements are initiated by the motor cortex of the cerebral cortex. Regulates balance.

A

Cerebellum

29
Q

What is the inner or central area of the brain

A

Diencephalon

30
Q

What are the two divisions of the diencephalon

A

Thalamus and hypothalamus

31
Q

In the diencephalon which part is the gateway and acts like a relay station

A

Thalamus

32
Q

In the diencephalon which part regulates body homeostasis and is the primary controller of the pituitary gland, temp control, thirst control, water control thru kidney

A

Hypothalamus
