BIOD 152 Module 2 Exam | Anatomy and Physiology 2 | Actual Q&A
with Rationale (BIOD152 Module 2 Exam) | Portage Learning Online
Question 1 ( pts)
This is the most superficial layer of the brain meninges.
Dura mater
Rationale: Correct.
Question 2 ( pts)
The _ fissure separates the right and left cerebral hemispheres.
Median longitudinal
Rationale: Correct.
Question 3 ( pts)
What is the purpose of the blood-brain barrier? Describe its maintenance from a
cellular level.
The purpose is to diffuse and to prevent some particles from entering the CNS tissue
and allowing the brain and spinal cord separate from general circulation. The
maintenance of the blood-brain barrier provide a stable chemical environment for the
nervous system. 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.
Rationale: Correct.
Question 4 ( pts)
All the following are functions of the hypothalamus except:
• Maintain homeostasis
• Controls the pituitary gland
• Links the nervous and endocrine systems
• Relays sensory impulses to the cerebrum
, Rationale: Correct (this is not a function of the hypothalamus).
Question 5 ( pts)
This ventricle is located anterior to the cerebellum.
• Lateral
• Medial
• Third
• Fourth
Rationale: Correct.
Question 6 ( pts)
This region of the brain acts to coordinate multiple sources of sensory information.
• Primary sensory cortex
• Primary motor cortex
• Association area
• Precentral gyrus
• Postcentral gyrus
Rationale: Correct.
Question 7 ( pts)
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?
• Broca’s area
• Wernicke’s area
• Occipital lobe
• Parietal lobe
• Primary sensory cortex
Rationale: Correct.
