# Question Points Answer
1 a. Most superficial layer of the brain meninges. 3 a. Dura mater
b. This layer of the meninges is tightly attached to the brain. b. Pia mater
2 a. The ______ fissure separates the cerebrum from the cerebellum. 3 a. Transverse fissure.
b. The ______ fissure separates the right and left cerebral hemispheres. b. Median Longitudinal fissure
3 a. Describe the function of the brain ventricles. 4 a. The brain ventricles are responsible for the creation and circulation of
ta
cerebrospinal fluid (by the choroid plexus) which helps to cushion and protect
the brain.
b. What is the purpose or the blood-brain barrier? Describe its maintenance
from a cellular level.
b. The blood-brain barrier is a diffusion barrier which prevents most particles from
entering the central nervous system tissue, keeping the brain and spinal cord
separate from general blood circulation. The blood-brain barrier is formed by
da
the relatively impermeable brain capillaries, due to the glial cells astrocytes.
Maintenance of the blood-brain barrier is important to provide a stable
chemical environment for the nervous system.
4 a. All the following are functions of the hypothalamus except. 2 a. filters out unimportant sensory information
- regulate sleep
- links to nervous and endocrine systems
- filters out unimportant sensory information
- regulates water balance
on
5 a. What is the largest portion of the brain. 2 a. cerebrum
- cerebellum
- cerebrum
- corpus callosum b. fourth
- singlet gyrus
b. This ventricle is located anterior to the cerebellum.
ta
- lateral
- medial
- third
- fourth
6 a. This region of the brain acts to coordinate multiple sources of sensory 2 a. association area
da
information.
- primary sensory cortex
- primary motor cortex b. frontal lobe
- association area
- precentral gyrus
- postcentral gyrus
b. This region of the brain controls decision making skills.
- frontal lobe
- cerebellum
- occipital lobe
- temporal lobe
- primary sensory cortex
7 a. A patient is having difficulty understanding language but is able to still 2 a. Wernicke’s area
speak fluently. The patients dermatomes are intact. Which area of the
brain is most likely damaged.
- Broca’s area b. Broca’s area

# Question Points Answer
b. A patient is having difficulty producing speech sounds, but other motor
movements are normal. Which area of the brain is most likely damaged.
(See a options.)
8 a. What is muscle tone and how is it maintained. 2 a. Muscle tone is the extent of contraction in a muscle while in a relaxed state.
This is maintained by the cerebellum and helps to keep joints in place.
b. How are memories stored and retrieved in the brain. Include a specific
brain region. b. Memories are not stored in one specific area within the brain but instead are
stored throughout the cerebral hemispheres. The hippocampus acts as a
memory center to help with memory storage and retrieval. The involvement of
the limbic system explains why emotionally charged events result in our most
vivid memories.
9 a. Which statement is false concerning the brainstem. 2 a. the midbrain portion of the brain stem is continuous with the spinal cord.
- the midbrain portion of the brain stem is continuous with the spinal
cord
- the pons helps to regulate breathing b. the midbrain helps to regulate breathing
ta
- the midbrain contains the superior and inferior colliculi
- the medulla contains reflex centres to regulate vasoconstriction
b. Which statement is false concerning the brainstem.
- the medulla portion of the brainstem continuous with the spinal cord
- the medulla contains reflex centers to regulate vasoconstriction
da
- the midbrain contains the superior and inferior colliculi
- the midbrain helps to regulate breathing
10 a. Which of the following is true concerning the cerebellum. 2 a. the anterior lobe receives information from the body trunk
- the grey matter is internal while the white matter is external
- the cerebellum works plan body movements by relaying information
to the spinal cord b. the cerebellar peduncles are located posteriorly.
- the anterior lobe receives information from the body trunk
on
- the vermis coordinates the trunk and shoulder movements
b. Which of the following is FALSE concerning the cerebellum.
- the gray matter is external while the white matter is internal
- the cerebellar peduncles are located posteriorly.
- the anterior lobe receives information from the body trunk.
- the vermis coordinates arm movements.
ta
11 a. Alzheimer's disease impacts which regions of the brain. 2 a. all of the above

- parietal lobe b. impaired ability to swallow
- hippocampus
- all of the above
da
b. Which of the following is most likely a symptom of ALS.
- impaired ability to swallow
- decreased sensation to the hands
- shrinkage of cerebral cortex
- increased size of the brain
- all of the above.
12 a. Which of the following is true concerning a CVA. 2 a. a haemorrhagic stroke is due to a broken blood vessel
- ischemic stroke is also known as brain bleed
- TIA is form of haemorrhagic stroke
- stroke survivors never regain any lost function b. an ischemic stroke is also known as a "brain bleed"
- a haemorrhagic stroke is due to a broken blood vessel
b. Which of the following is false concerning a CVA?
- an ischemic stroke is also known as a "brain bleed"
- a TIA is a form of an ischemic stroke
- stroke survivors may regain some lost functions through therapy
- a hemorrhagic stroke is due to a broken blood vessel
13 a. A patient is unable to extend his fourth and 5th digits when asked to open 2 a. ulnar nerve damage
his hand what is most likely the cause.
- CBA in the frontal lobe
b. median nerve damage (Carpal Tunnel Syndrome)
