BIOD 152 Module 2 EXAM.
This is the most superficial layer of the brain meninges - ANS Dura Mater (Menix)
This layer of the meninges is tightly attached to the brain. - ANS Pia mater (Menix)
The _______ fissure separates the right and left cerebral hemispheres. - ANS median
The ______ fissure separates the cerebrum from the cerebellum. - ANS Transverse
Describe the function of the brain ventricles. - ANS 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. - ANS
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: - ANS Relays sensory impulses to the
cerebrum
This ventricle is located anterior to the cerebellum. - ANS fourth
What is the largest portion of the brain? - ANS Cerebrum
This region of the brain acts to coordinate multiple sources of sensory information. - ANS Association
area
This region of the brain controls decision making skills - ANS 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? - ANS 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? - ANS Broca's area
Describe how memories are stored and retrieved in the brain. Include a specific brain region. - ANS
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? - ANS 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? - ANS The midbrain helps regulate breathing
Which of the following is true concerning the cerebellum? - ANS The anterior lobe receives
information from the body trunk.
Which is most likely a symptom of ALS? - ANS Impaired ability to swallow
Which of the following is true concerning a CVA? - ANS A hemorrhagic stroke is due to a broken
blood vessel.
Which of the following is false concerning CVA? - ANS 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? - ANS 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? - ANS Ulnar nerve damage
Label the following spinal cord regions in the diagram below: - ANS 1. Lateral Column 3. Gray
Commissure 4. Anterior Column 6. Anterior or Ventral Horn 11. Ventral Root
