Week 1

Question 1

Area of brain that is very susceptible to injury. About 1/3 of the hemispheric surface. Includes primary motor cortex and Broca’s area (speech production).

Answer 1

Frontal Lobe

Question 2

Functions of Frontal Lobe. . .

Answer 2

executive functions, planning, prediction, personality, insight, motor movement, expressive language.

Question 3

Largest Lobe of the Brain

Answer 3

Frontal Lobe

Question 4

Damage to Frontal Lobe may cause. . .

Answer 4

apathy, disinhibition & denial, decreased insight, attention, motivation & self-monitoring, and speech and language disorders.

Question 5

Area of the brain responsible for auditory reception, integration/association of auditory information, memory (medial surface), lexical processes, hearing, semantic processes, and lexical/semantic processing.

Answer 5

Temporal Lobe

Question 6

Damage to the Temporal Lobe may cause. . .

Answer 6

comprehension deficits, decreased auditory processing and/or reading skills, decreased memory and NEW learning of information.

Question 7

Area of the brain responsible for primary sensory cortex, integration of sensations, spatial orientation/perception, and body awareness.

Answer 7

Parietal Lobe

Question 8

Damage to the Parietal Lobe may cause. . .

Answer 8

visual/tactile agnosia (lack of awareness of sensory information), difficulty with right/left orientation, left neglect may occur after right parietal damage. Difficulty locating/recognizing parts of the body.

Question 9

Area of the brain responsible for primary vision cortex, visual association, reading.

Answer 9

Occipital Lobe

Question 10

Damage to the Occipital Lobe may cause. . .

Answer 10

Partial or complete blindness (visual field cuts = TBI or Right Hemisphere), visual processing difficulty, and reading difficulty.

Question 11

Protect/suspend brain within skull = Protective Layers - below the skull

Answer 11

Meninges

Question 12

“tough mother” - thick layer, attaches to the skull

Answer 12

Dura mater

Question 13

“spider’s web” - middle avascular layer, attaches to dura

Answer 13

Arachnoid mater

Question 14

Contains cerebrospinal fluid arteries and veins

Answer 14

Subarachnoid space

Question 15

“tender mother” - inner most vascular layer - attaches to outer surface of the brain

Answer 15

Pia mater

Question 16

Carotid System

Answer 16

External and Internal Carotid

Question 17

External Carotid supplies. . .

Answer 17

the facial regions - facial muscles, forehead, oral & nasal cavities.

Question 18

Internal Carotid supplies. . .

Answer 18

anterior cerebral artery (ACA) and middle cerebral artery (MCA).

Question 19

Supplies posterior part of the brain

Answer 19

Vertebral System

Question 20

Supplies blood to the prefrontal, frontal, and parietal lobes and part of the supply to the corpus striatum and internal capsule

Answer 20

Anterior Cerebral Artery (ACA)

Question 21

Interruption of blood flow in the anterior cerebral artery could cause. . .

Answer 21

Contralateral loss of somatic sensory and paralysis of leg/foot AND/OR disorder of executive functioning skills and altered personality.

Question 22

Supplies blood to the lateral surfaces of the frontal, temporal, and parietal lobes.

Answer 22

Middle Cerebral Artery (MCA)

Question 23

Interruption of blood flow in the middle cerebral artery (most common) could cause. . .

Answer 23

Contralateral hemiplegia of upper body, contralateral hemianesthesia, aphasia (receptive and/or expressive), alexia/agraphia (reading/writing deficits), visual0spatial deficits, and cognitive impairments (very detrimental to language)
