BIOD 152 Module 2 EXAM questions
and answers
This is the most superficial layer of the brain meninges - correct answer Dura Mater (Menix)
This layer of the meninges is tightly attached to the brain. - correct answer Pia mater (Menix)
The _______ fissure separates the right and left cerebral hemispheres. - correct answer median
The ______ fissure separates the cerebrum from the cerebellum. - correct answer Transverse
Describe the function of the brain ventricles. - correct answer There are four ventricles in the interior of
the brain, chambers filled with cerebrospinal fluid which is produced there. Once formed the CSF
circulates through the ventricles and into the subarachnoid space bathing and floating the brain.
What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular level. - correct
answer 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 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.
All the following are functions of the hypothalamus except: - correct answer Relays sensory impulses to
the cerebrum
This ventricle is located anterior to the cerebellum. - correct answer fourth
What is the largest portion of the brain? - correct answer Cerebrum
This region of the brain acts to coordinate multiple sources of sensory information. - correct answer
Association area
, This region of the brain controls decision making skills - correct answer Frontal lobe
A patient is having difficulty understanding language but is sill able to speak fluently. The patient's
dermatomes are intact. Which area of the brain is most likely damaged? - correct answer Wernicke's
area
A patient is having difficulty producing speech sounds, but other motor movements are normal. Which
area of the brain is most likely damaged? - correct answer Broca's area
Describe how memories are stored and retrieved in the brain. Include a specific brain region. - correct
answer Memories 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.
What is muscle tone and how is it maintained? - correct answer Muscle tone is the degree at which
muscles remain partially contracted while at rest. Muscle tone is continuously monitored and
maintained by the cerebellum to keep bones and joints in place.
Which statement is false concerning the brainstem? - correct answer The midbrain helps regulate
breathing
Which of the following is true concerning the cerebellum? - correct answer The anterior lobe receives
information from the body trunk.
Which is most likely a symptom of ALS? - correct answer Impaired ability to swallow
Which of the following is true concerning a CVA? - correct answer A hemorrhagic stroke is due to a
broken blood vessel.
Which of the following is false concerning CVA? - correct answer An ischemic stroke is also known as a
"brain bleed"
