Biod 152 final exam portage learning 2026 3) Describethefunctionofthebrainventricles.
Your Answer: The brain ventricles are important because they
Update help circulate and produce cerebrospinal fluid which is essential to keeping the
MODULE/LAB 1 brain
afloat and protecting it.
1) This layer of the meninges is tightly attached to the brain. Pia mater
(menix) 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
1)) This is the most superficial layer of the brain meninges Dura mater
central nervous system tissue, keeping the brain and spinal cord separate from general blood
circulation..

Lab 1)
Logitudinal Fissure The folds in the region above (indicated by the blue pin) are called: Folia
2) The fissure separates the right and left cerebral hemispheres. 4) All the following are functions of the hypothalamus except:
Filters out unimportant sensory information
Median longitudinal
2) The _transverse fissure separates the cerebrum from the cerebellum 4) All the following are functions of the hypothalamus except:
D. Relays sensory impulses to the cerebrum
LAB 4
Injury to the area of the brain (indicated by the pin) above

A. Correct! An ischemic stroke is also known as a “brain bleed”.
7) A patient is having difficulty producing speech sounds, but other
motor movements are normal. Which area of the brain is most likely 12 Which of the following is true concerning a CVA?
damaged? - Broca’s area A hemorrhagic stroke is due to a broken blood vessel.

patient's dermatomes are intact. Which area of the brain is most likely damaged? B.
Wernicke’s area
13) A patient has decreased hand strength in her right hand. She also has
8) Describe how memories are stored and retrieved in the brain. Include a specific brain numbness in her first three digits. What is most likely the cause? Carpal tunnel
region. Memories are not stored in one specific area within the brain but instead are stored syndrome
throughout the cerebral hemispheres. The hippocampus acts as a memory center to help
with memory storage and retrieval. 14) Label the following spinal cord regions in the diagram below: 1: Posterior (Dorsal) column
5: Anterior median fissure
8) What is muscle tone and how is it maintained? 6: Posterior (Dorsal) horn
Your Answer: Muscle tone is the amount of tension of a muscle at rest. It is 9: Dorsal root
controlled and maintained by the muscle spindles. 11: DRG (Dorsal Root ganglion)
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.

A. Occipital lobe
B. Frontal lobe
