This is the most superficial layer of the brain meninges - answer Dura Mater (Menix)
This layer of the meninges is tightly attached to the brain. - answer Pia mater (Menix)
The _______ fissure separates the right and left cerebral hemispheres. - answer
median
The ______ fissure separates the cerebrum from the cerebellum. - answer Transverse
Describe the function of the brain ventricles. - 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. - 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: - answer Relays sensory
impulses to the cerebrum
This ventricle is located anterior to the cerebellum. - answer fourth
What is the largest portion of the brain? - answer Cerebrum
This region of the brain acts to coordinate multiple sources of sensory information. -
answer Association area
, This region of the brain controls decision making skills - 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? -
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? - answer Broca's area
Describe how memories are stored and retrieved in the brain. Include a specific brain
region. - 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? - 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? - answer The midbrain helps
regulate breathing
Which of the following is true concerning the cerebellum? - answer The anterior lobe
receives information from the body trunk.
Which is most likely a symptom of ALS? - answer Impaired ability to swallow
Which of the following is true concerning a CVA? - answer A hemorrhagic stroke is
due to a broken blood vessel.
Which of the following is false concerning CVA? - answer An ischemic stroke is also
known as a "brain bleed"
A patient has decreased hand strength in her right hand. She also has numbness in her
first three digits. What is most likely the cause? - answer Carpel tunnel syndrome
A patient is unable to extend his fourth and fifth digits when asked to open his hand.
What is most likely the cause? - answer Ulnar nerve damage
Label the following spinal cord regions in the diagram below: - answer 1. Lateral
Column 3. Gray Commissure 4. Anterior Column 6. Anterior or Ventral Horn 11. Ventral
Root
What cranial nerve is highlighted in blue (also indicated by the arrow) in the figure
