tract that is responsible for large muscle
movement of the upper limb.

A

rubrospinal tract

38
Q

The control center of our body.

A

brain

39
Q

The largest portion of the brain and located at the frontal aspect of the brain. It is composed of the right and left hemisphere

A

cerebrum

40
Q

Connects the cerebral hemispheres

A

corpus callosum

41
Q

left and right hemisphere were separated by _________

A

falx cerebri

42
Q

left and right parts of cerebrum

A

Cerebral Hemisphere

43
Q

44
Q

Shallow grooves in surface (spaces that
separates the gyri)

Q

sulcus that is prominent on the
topmost portion of the cerebrum.

47
Q

longitudinal fissures separates _____

A

separates the cerebral
hemispheres

48
Q

transverse fissures separates ______

A

Separates cerebrum from
cerebellum

49
Q

5 lobes of the cerebrum

A

frontal lobe
parietal lobe
temporal lobe
occipital lobe
insula (island of reil)

50
Q

this lobe is located at the front side of the brain. The part of the brain that controls important
cognitive skills in humans.

A

51
Q

area that is associated with speech production. Located in the region of the frontal lobe of the dominant hemisphere.

A

broca’s area

52
Q

This lobe is a major interpreter of the sensory world around the body. Is also considered as the primary sensory area.

A

Parietal Lobe

53
Q

this lobe is at the lower lobe of the cortex sitting close to the ear level within the skull. It is largely responsible for creating and preserving both conscious and long term memory and responsible for hearing and sequencing the organization.

responsible for understanding spoken
languages.

Q

The function of this lobe is
self-awareness, perception, and recognition.

A

Sensory Speech Area (Wernicke’s Area)

60
Q

this sensory area is located at the occipital lobe that interprets vision as the name implies.

A

Visual Area

61
Q

this sensory area is located in the temporal lobe and interprets hearing.

A

Auditory Area

62
Q

this sensory area is located near the base of the central sulcus, responsible for the sensation of taste.

A

Sensory Area for Taste

63
Q

this sensory area arises from the centers deep within the cerebrum.

A

Sensory Area for Smell

64
Q

These are the regions that are not primary motor nor
primary sensory areas. These are widespread throughout the cerebral cortex and functions in analyzing and interpreting sensory experiences.

A

Association Areas

65
Q

motor area that is located at the frontal lobes and is responsible for the control of the voluntary muscles.

A

Primary Motor Areas

66
Q

this motor area controls the muscles needed for speech.

A

broca’s area

67
Q

this motor area is located above the Broca’s Area, controls the voluntary movement of the eyes as well as the eyelids.

A

Frontal Eye Field

68
Q

what hemisphere is dominant in most individuals?

A

left hemisphere

69
Q

if a person is right handed, the person is more likely to have a ______

A

dominant left hemisphere

70
Q

this hemisphere controls speech, writing,
reading, verbal skills, analytical skills, as well as
computational skills.

A

dominant hemisphere

71
Q

this hemisphere controls nonverbal
tasks, motor tasks, understanding and interpreting
musical and visual patterns, as well as provides
emotional and intuitive thought processes.

A

nondominant hemisphere

72
Q

Situated at the lateral aspect of the brain.

A

diencephalon

73
Q

Found at the posterior portion of the brain.

A
