VERIFIED CORRECT ANSWERS
WITH DIAGRAMS GRADED A+.
MODULE/LAB 1
1) This layer of the meninges is tightly attached to the brain. Pia mater (menix)
1)) This is the most superficial layer of the brain meninges Dura mater
Lab 1)
Logitudinal Fissure
2) The fissure separates the right and left cerebral hemispheres. Median
longitudinal
2) The _transverse fissure separates the cerebrum from the cerebellum
, 2
Lab 2 Caudal, cerebellum
3) Describethefunctionofthebrainventricles.
Your Answer: The brain ventricles are important because they help
circulate and produce cerebrospinal fluid which is essential to keeping the brain
afloat and protecting it.
3) What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular level.
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..
3)
The folds in the region above (indicated by the blue pin) are called: Folia
4) All the following are functions of the hypothalamus except:
Filters out unimportant sensory information
4) All the following are functions of the hypothalamus except:
D. Relays sensory impulses to the cerebrum
, 3
LAB 4
Injury to the area of the brain (indicated by the pin) above would
most likely cause impaired: Vison
5) What is the largest portion of the brain? Cerebrum
5) This ventricle is located anterior to the cerebellum. fourth
6) This region of the brain acts to coordinate multiple sources of
sensory information. C. Association area
6) This region of the brain controls decision making skills. - Frontal lobe
7) A patient is having difficulty producing speech sounds, but other motor movements
are normal. Which area of the brain is most likely damaged? - Broca’s area
7) A patient is having difficulty understanding language but is still able to speak fluently. The
patient's dermatomes are intact. Which area of the brain is most likely damaged? B. Wernicke’s
area
8) Describe how memories are stored and retrieved in the brain. Include a specific brain
region. 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.
8) What is muscle tone and how is it maintained?
Your Answer: Muscle tone is the amount of tension of a muscle at rest. It is
controlled and maintained by the muscle spindles.

9) Which statement is false concerning the brainstem?
- The midbrain portion of the brainstem is continuous
with the spinal cord.
10) Which of the following is true concerning the cerebellum?
- The anterior lobe receives information from the body trunk.
10) Which of the following is false concerning the cerebellum? B. Correct! The cerebellar peduncles
are located posteriorly.
11) Alzheimer's disease impacts which region(s) of the brain?
A. Occipital lobe
B. Frontal lobe
C. Parietal lobe
D. Hippocampus
E. Correct! All the above
11) Which of the following is most likely a symptom of ALS? Impaired ability to swallow
12) Which of the following is false concerning a CVA?
A. Correct! An ischemic stroke is also known as a “brain bleed”.
12 Which of the following is true concerning a CVA? A hemorrhagic stroke
is due to a broken blood vessel.
13) A patient is unable to extend his fourth and fifth digits when asked to open his hand. What is most
likely the cause? C. Correct! Ulnar nerve damage
13) 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? Carpal
tunnel syndrome
14) Label the following spinal cord regions in the diagram below: 1: Posterior (Dorsal) column
5: Anterior median fissure
6: Posterior (Dorsal) horn
9: Dorsal root
11: DRG (Dorsal Root ganglion)
