BIOD 152 MODULE 2 EXAM 2025
QUESTIONS
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"
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? - CORRECT 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? - CORRECT ANSWER>>>>Ulnar nerve damage
Label the following spinal cord regions in the diagram below: - CORRECT 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 below? -
CORRECT ANSWER>>>>Abducens
What cranial nerve is highlighted in blue (also indicated by the arrow) in the figure below? -
CORRECT ANSWER>>>>Oculomotor
What nerve is the cranial nerve below and what does it control? (highlighted in blue, and also
indicated by the arrow) - CORRECT ANSWER>>>>Motor: Shoulder movement
