Telencephalon

Question 1

Left Hemisphere Function

Answer 1

It favors the processing of discreet sequential rapidly changing information. Dominant for speech and language for most people.

Question 2

Right Hemisphere Function

Answer 2

Favors more spatial and holistic information. Emotion, facial recognition, speech intonation, melody, perception, and form

Question 3

Telencephalon

Answer 3

Largest part of the brain. Consists of two highly convoluted hemispheres. They are mirror images of each other.

Question 4

Corpus Callosum

Answer 4

It’s a tract that connects the two hemispheres and it allows them to communicate with each other. It is located deep to the longitudinal fissure.

Question 5

Cortex

Answer 5

The outer covering of the cerebral hemisphere. It’s mainly comprised of grey matter that overlies an inner core of white matter.

Question 6

Longitudinal Fissure

Answer 6

Separates the cerebral hemispheres.

Question 7

Gray Matter

Answer 7

Mostly composed of cell bodies.

Question 8

White Matter

Answer 8

Composed of myelinated processes, like Axons.

Question 9

Gyri

Answer 9

The hills on the cortex.

Question 10

Sulci

Answer 10

The grooves on the cortex.

Question 11

Fissures

Answer 11

Extra deep sulci

Question 12

Frontal Lobe Function

Answer 12

Responsible for the planning and initiation of movements and behaviors.

Question 13

Precentral Gyrus

Answer 13

AKA motor strip. Brodmann’s area 4. Responsible for activating and controlling the muscles on the opposite side of the body

Question 14

Premotor Cortex

Answer 14

Brodmann’s area 6. Responsible for complex skilled movements, like hand-eye coordination, finger movement, speech something??

Question 15

Prefrontal Cortex

Answer 15

Brodmann’s area 10-12. Considered the anatomical area of intelligence. Reasoning, abstract thinking, self monitoring, planning, decision making, pragmatics

Question 16

Broca’s Area

Answer 16

Speech Motor area. Brodmann’s area 44. Controls jaw, lip, tongue, and vocal fold movement. More specifically, responsible for planning and coordinating movement.

Question 17

Postcentral Gyrus

Answer 17

Brodmann’s area 1-3. Primary sensory complex. Plays a significant role in receiving and interpreting sensory information from the opposite side of the body. Responsible for pain, temperature, pressure, and touch.

Question 18

Angular Gyrus

Answer 18

Brodmann’s area 39. Responsible for comprehension of written material

Question 19

Parieto-occipital line

Answer 19

line where the occipital lobe starts

Temporal Lobe

Answer 20

Auditory reception and receptive language processing

Question 21

Heschel’s Gyrus

Answer 21

Brodmann’s area 41. Auditory reception and processing

Question 22

Wernicke’s Area

Answer 22

Brodmann’s area 22. Responsible for the comprehension of verbal language, the analysis and elaboration of speech sounds, and verbal memory

Question 23

Occipital Lobe

Answer 23

Responsible for recognition, reception, and interpretation of visual stimuli

Question 24

Insula

Answer 24

Deep to the lateral sulcus. Responsible for visceral functions, like reflexes, feeding, defensive behaviors, mating, aggression, anxiety, and fear

Question 25

Connection Fibers/Tracts

Answer 25

The primary subcortical structures. Allows the areas of the brain to communicate

Question 26

Projection Fibers/Tracts

Answer 26

Convey impulses to and from the cerebral cortex and more remote regions of the Central Nervous System

Question 27

Corona Radiata

Answer 27

Diffuse pattern of origin from almost all areas of the brain. The pattern of emergence

Association Fibers/Tracts

Answer 28

Interconnects different regions in the same hemisphere

Question 29

Short Association Fibers/Tracts

Answer 29

Connect contiguous gyri

Question 30

Long Association Fibers/Tracts

Answer 30

Connect more distant areas within the same hemisphere

Question 31

Uncinate Fasciculus

Answer 31

Connects frontal lobe to temporal lobe

Question 32

Arcuate Fasciculus

Answer 32

Connects speech production in the frontal lobe to the speech understanding area of the temporal lobe

Question 33

Cingulum

Answer 33

Connects the frontal and parietal lobes to the temporal lobe

Question 34

Commissural Tracts

Answer 34

Connect an area of one cerebral hemisphere to the corresponding area in the other cerebral hemisphere
