Q

What is the cerebral cortex?

A

The thin layer of gray matter what makes up the outer most layer of the cerebrum

21
Q

In what region are 75% of neurons and neuron cell bodies contained?

A

Cerebral cortex

22
Q

What is the cerebral cortex mainly responsible for?

A

Memories, intelligent, and personality

23
Q

What does the brainstem do?

A

Regulates many of the Bodys automatic functions

24
Q

What is Wernicke’s area?

A

The sensory speech area

25
Q

Where is the cutaneous sensory area located?

A

In the parietal lobe

26
Q

Where is the visual area of the brain located?

A

In the occipital lobe

27
Q

Where is the auditory area of the brain located?

A

In the temporal lobe

28
Q

Where is the sensory area for taste in the brain located?

A

Near the base of the central sulcis

29
Q

Where is the sensory area for smell located?

A

Deep in the temporal lobe

30
Q

What are the 4 functions of the frontal lobe association areas?

A

Concentration, planning, problem-solving, and behavior

31
Q

What is the parietal lobe association area do?

A

Understanding words

32
Q

What is the occipital lobe association area?

A

Analyzing

33
Q

What is the insula association area?

A

Translating sensory Info with proper emotional response

34
Q

What are the two types of memory?

A

Short term/working memory and long-term memory

35
Q

How does short-term memory work?

A

Neurons connected in a circuit are stimulated repeatedly and when the impulse flow stops so does the memory associated with it

36
Q

How does long term memory work?

A

By changing the structure or function of a neuron in enhancing synaptic transmission

37
Q

What is another name for basal nuclei?

A

Basal Ganglia

38
Q

What is ganglia?

A

Masses of gray matter deep within the cerebral hemisphere

39
Q

What does the basal nuclei do?

A

Produces dopamine and helps control voluntary movement

40
Q

Where is the Diencephalon located in the brain?

A

Between the cerebral hemispheres and above the brainstem

41
Q

What is the function of the thalamus?

A

To receive sensory impulses (Except for smell)

42
Q

What are the three functions of the hypothalamus?

A

To maintain homeostasis, to control basic body functions, and to link the nervous system and endocrine system

43
Q

What does the limbic system do in the brain?

A

Controls behavior oriented toward survival

44
Q

What are the three parts of the brain stem?

A

The midbrain, pons, and medulla oblongata

45
Q

What is the function of the midbrain?

A

Visual and auditory reflexes

46
Q

What is the function of the pons?

A

Regulates breathing rhythm

47
Q

What is the function of the medulla oblongata?

A

Cardiac and respiratory control

48
Q

Where is the cerebellum located?

A

Inferior to the occipital lobes And posterior to the pons and the medulla oblongata

49
Q

What are the three functions of the cerebellum?

A

Integrate sensory info, maintains posture, and coordinate starts with muscle activity
