1

3 embryonic regions of the brain

prosencephalon, mesencephalon, and rhombencephalon

2

prosencephalon

forebrain

3

mesencephalon

midbrain

4

rhombencephalon

hindbrain

5

surround brain

meningess

6

dura mater

superficial, tense ct surround brain and has projections that extend into the brain

7

The right and left cerebral hemispheres are separated from each other by

  • the longitudinal fissure.
8

The cerebellum is _________________ to the cerebrum.

  • caudal
9

what structure of the brain makes up 85% of brain volume?

  • cerebrum
10

What is the brain structure that is described as a 3 millimeter layer of gray matter that houses neural cell bodies and acts as a computer?

  • Cerebral cortex
11

Damage to what area of the frontal lobe results in preservation of word comprehension but compromised word formation?

  • Broca‚Äôs area
12

The cardiac, vasomotor, and respiratory centers are found in

the medulla oblongata.

13

From superficial to deep, the meninges occur in this order:

  • dura mater, arachnoid, pia mater.
14

The right and left cerebral hemispheres are separated from each other by

the longitudinal fissure.

15

Which of the meninges is between the outer and inner meninges?

Arachnoid mater

16

largest region of the brain

forebrain

17

forebrain consists of

cerebrum and diencephalon

18

smallest region of the brain

midbrain

19

between the forebrain and hindbrain

midbrain

20

the midbrain is made up of

pons, the medulla oblongata, and cerebellum

21

connects to the spinal cord at the level of the foramen magnum

hindbrain

22

olfactory

recieves sensory info from the nose

23

optic

recieves sensory info from the eyes

24

oculomotor

transmits motor info to move eye

25

trochlear

transmits motor info to move eye

26

trigeminal

transmits both info to head

27

abducens

motor to move eye

28

facial

recieves sense info from tongue and motor info to the head muscles

29

vestibulocochlear

receives sense info from abdomen, thorax, neck, and root of the tongue;

transmits motor info to pharynx, larynx, controls autonomic heart functions, digestive organs, spleen, and kidneys

30

accessory

motor nerve to the muscles of the neck that move neck

31

hypoglossal

motor nerve to the tongue

32

Wernicke's area

used in the formation of speech or language

33

occipital lobe

serves as the primary visual area of the brain

34

located between the occipital lobe and the cerebellum is

transverse fissure

35

olfaction

sense of smell

36

broca area

motor speech area

37

brocas area is on the

left side of the brain, frontal

38

lateral fissure (sulcus)

separates the temporal lobe from the frontal and parietal

39

primary auditory cortex

interprets hearing impulses sent from the inner ear

40

justation

sense of taste

41

rostral

anterior

42

caudal

posterior

43

85% of brain

cerebrum

44

motor formation

cerebellum

45

separates 2 cerebral hemisphere

longitudinal fissure

46

"brain bark", layer of gray matter with extensive folds to increase surface area

cerebral cortex

47

gyri

ridges

48

sulci/ fissure

depression

49

has myelinated axons

white matter

50

gray matter contains

neural cell bodies

51

pia mater

in direct contact with the brain

52

dura mater

dense ct, periosteal layer then meningeal layer

53

what has direct contact with meninges

cranial bones

54

cerebrospinal fluid

clear liquid fills ventricles and canals and bathes the brain's external surface

55

buoyancy

floats brain so its neutrally buoyant

56

protection

cushions from hitting inside of skull

57

chemical stability

rinses away wastes

58

voluntary motor functions and areas for planning, mood and social judgement

frontal

59

sensory reception & integration sensory info

parietal

60

visual

occiptal

61

hearing, smell, learning, memory, emotional behavior, taste

temporal

62

posterior border

central sulcus

63

transverse sulcus

separates cerebellum from occipital and parietal

64

latral sulcus

separates cerebellum from everything else

65

left cerebral hemisphere

language and reasoning

66

right cerebral hemisphere

space/ pattern perception, artistic awareness, imagination, and music comprehension

67

cerebral hemispheres are connected by

corpus callosum
