Brain and Deep systems

Question 1

Which of these does NOT contribute significantly to the
physical protection of the brain?
A.cranium
B.subarachnoid space
C.cerebrospinal fluid (CSF)
D.dura mater
E.astrocytes

Answer 1

E Astrocytes use the foot process to tighten junctions between the blood vessel cells to allow for restricted flow of specific nutrients and compounds
Small lipid molecules can be allowed access

Question 2

Cerebrospinal fluid (CSF) is produced by the?
A.choroid plexus
B.arachnoid villi
C.frontal sinuses
D.pia mater
E.ventricles

Answer 2

A Choroid plexus is found within the 3rd and 4th ventricles, yet the choroid plexus forms the CSF

Question 3

A collection of axons that carries information between
areas of the central nervous system is called a/an?
A.axon hillock
B.varicosity
C.tract
D.axon
E.dendrite

Answer 3

C tract is a group of axons

Question 4

The blood
brain barrier will NOT prevent entry into the CNS
for which of the following?
A.red blood cells
B.lipid soluble molecules
C.proteins
D.bacteria
E.haemoglobin

Answer 4

B as they are small

Question 5

Which is
NOT housed in the medulla oblongata?
A. centres for blood pressure control
B. centres for control of vomiting
C. centres for control of eye movement
D. centres for control of breathing
E. the pyramids, where tracts cross to the opposite side of the body

Answer 5

C Medulla Oblongata controls involuntary movement not voluntary

is the?
A. basal ganglia
B. suprachiasmatic nucleus
C. hippocampus
D. corpus callosum
E. diffuse modulatory system

Answer 6

D

Corpus is the white matter that conjoins the two hemispheres

Question 7

Answer 7

fear and arousal

Question 8

Question 9

Which functions in the control of movement?
A. hippocampus only
B. amygdala only
C. basal ganglia only
D. hippocampus and amygdala
E. all of the above function in the control of movement

Answer 9

C Basal ganglia only Controls motor neurons

Degeneration causes parkinsons disease

Question 10

Wernicke’s area is responsible for what?

Answer 10

Comprehension of language (written or verbal)

Damage causes receptive aphasia

Question 11

Broca’s area is responsible for what?

Answer 11

Speech reproduction
Damage causes expressive aphasia
Comprehension still intact

Question 12

Broca’s area is mainly associated with?
A. breathing
B. producing speech
C. recognising objects
D. comprehension of problems
E. determining the colour of objects

Answer 12

B Producing speech

Question 13

What area of the brain is responsible for breathing

Answer 13

Pons

Question 14

What area of the brain is responsible for recognising objects visually?

Answer 14

Visual cortex (occipital lobe)

Question 15

Comprehension of problems arises in the outer layer of
neurons of which of the following?
A. amygdala
B. basal ganglia
C. hippocampus
D. cerebrum
E. amygdala and hippocampus

Answer 15

D Cerebrum (prefrontal lobe)

Question 16

Which is NOT associated with the diffuse modulatory
systems of the brain?
A. sleep wake cycles
B. proprioception
C. pain
D. attention
E. reward

Answer 16

B. Proprioception

Diffuse modulatory system is responsible for hormonal systems. Nordrenergic, Serotonergic, dopaminergic, cholinergic, histaminergic

Question 17

What is the noradrenergic system responsible for

Answer 17

Attention, arrousal, sleep/wake cycles, learning, memory, pain and mood

Question 18

What is the Serotonergic system responsible for

Answer 18

Lower nuclei: Pain and locomotion

Upper nuclei: Sleep and wake cycle, mood and emotional behaviours (Depression)

Question 19

What is the dopaminergic system responsible for

Answer 19

Motor control and Reward centres (addictive behaviours)

Question 20

What is the cholinergic system responsible for

Answer 20

Sleep wake cycles, arousal, learning/memory, sensory,, information passing through thalamus

Question 21

What is the histaminergic system responsible for

Answer 21

Regulation of awakeness, food intake, obesity, memory and cognition

Question 22

hippocampus is responsible for

Answer 22

Memory and learning

Question 23

Hypothalamus is responsible for

Answer 23

Eating drinking and homeostasis

Question 24

thalamus is responsible for

Answer 24

Relaying motor and sensory neuron information
