Brain Mapping Quiz 11/4

Question 1

what are the 5 major sections of the human brain

Answer 1

telencephalon
diencephalon
myelencephalon
metencephalon
mesencephalon

Question 2

Describe the telencephalon

Answer 2

L&R Hemisphere (thinking part of brain)
4 lobes (8 in total)
Cerebrum is another name for it
Directs: Motor (voluntary), sensory, learning and memory, language, and communication

Question 3

sulci-

Answer 3

a groove, crevice, or furrow in medicine (brain tissue)

Question 4

gyri-

Answer 4

a ridge on the cerebral cortex (brain tissue)

Question 5

cerebral cortex (for telencephalon)

Answer 5

-highest on intellectual function
neocortex (in newborns)
-function: sensory, perception, motor, reasoning, thought, language

Question 6

corpus callosum

Answer 6

-the bands of fibers which connects the L & R hemispheres of the brain
-the corpus callosum is the information highway which allows connectivism

Question 7

Occipital lobe

Answer 7

-visual processing center
-visual cortex
-primary visual cortex is Brodmann area

involved in information related to sight

Question 8

Temporal lobe

Answer 8

-involved in auditory perception
-important for the processing of semantics in speech
-contains the hippocampus and plays a key role in the formation of long term memory
-emotion regulation

involved in comprehension, sound, speech

Question 9

Frontal lobe

Answer 9

-dopamine-sensitive neurons in the cerebral cortex
-socially accepted emotions/behaviors
-non task long term memory
-future executive decision making, problem solving, planning and speech (intelligence)
-3 main divisions of the frontal lobe: prefrontal cortex, premotor area, motor area

involved in speaking, planning, judging, abstract thinking, and personality aspects.

Question 10

parietal lobe

Answer 10

-sensory perception for determining sense and navigation
-knowledge of numbers and their relations
-manipulation of objects

involved in sense of touch and body position

Question 11

Limbic system

Answer 11

amygdale (almond shape, fear response)
hippocampus (sea horse, central to learning and memory)
septum
basal ganglia

Question 12

functions of the limbic system:

Answer 12

emotion (main), behavior, long term memory, olfaction, some movement

Question 13

What is part of the telencephalon?

Answer 13

-brain tissue (sulci and gyri)
-cerebral cortex
-corpus callosum
-FPOT (Frontal, parietal, occipital, and temporal lobes)
-The limbic system

Question 14

What is in the diencephalon?

Answer 14

thalamus and hypothalamus
cerebral cortex

Question 15

thalamus

Answer 15

-relay and processes information to the cerebral cortex (highest level of intelligence)
-sensation
-spatial sense
-motor signals
-regulations of consciousness
-sleep
-alertness

Question 16

cerebral cortex (for the diencephalon)

Answer 16

outmost layer of the brain responsible for all forms of conscious activity (highest level of intelligence)

Question 17

hypothalamus

Answer 17

-relay station for internal regulation
-direct communication with pituitary gland
-regulates: hunger, hormones, thermoregulation, heart rate, sleep rhythms, thirst, pupil control, emotions, bladder, hair growth, and memory

Question 18

glial cells

Answer 18

spider web of support that surround, insulate, and nourish the cerebral neurons.

Question 19

motor cortex

Answer 19

controls voluntary movements and sends messages from the brain out to the body

Question 20

somatosensory cortex

Answer 20

processes incoming sensations

Question 21

pons

Answer 21

the passway that transfers information through the brainstem to the cerebellum.

Question 22

medulla

Answer 22

controls important processes like the heartbeat, breathing, and blood pressure.

Question 23

insular lobe

Answer 23

involved in sensory processing, decision-making, and motor control
