BIOD 152 Module 2 Exam:50 Questions & Answers
Question 1
Which of the following is the most superficial layer of the brain meninges?
A) Subdural space
B) Pia mater (Menix)
C) Dura Mater (Menix)
D) Arachnoid meninx
Correct Answer: C
Rationale: The leathery dura mater is the double-layered outer meninx and the
most superficial layer of the central nervous system meninges.
Question 2
Which layer of the meninges is tightly attached to the surface of the brain?
A) Pia mater (Menix)
B) Dura mater (Menix)
C) Subarachnoid space
D) Arachnoid meninx
Correct Answer: A
Rationale: The inner pia mater meninx is a thin connective tissue tightly attached
directly to the brain.
Question 3
What specific fissure separates the right and left cerebral hemispheres from one
another? A) Lateral sulcus
,B) Transverse fissure
C) Median longitudinal fissure
D) Central sulcus
Correct Answer: C
Rationale: The median longitudinal fissure separates the left and right cerebral
hemispheres from one another.
Question 4
Which of the following fissures separates the cerebrum from the cerebellum? A)
Median longitudinal fissure
B) Transverse fissure
C) Central sulcus
D) Lateral sulcus
Correct Answer: B
Rationale: The transverse fissure separates the cerebrum from the cerebellum.
Question 5
Which of the following is true concerning the ventricles and cerebrospinal fluid
(CSF)? A) There are two ventricles in the brain which produce lymph fluid to drain
the meninges.
B) There are four ventricles that directly absorb blood from the dural sinuses.
C) The ventricles are blood-filled cavities that have no connection to the spinal
cord.
D) There are four ventricles in the interior of the brain, which are chambers filled
with CSF produced there.
, Correct Answer: D
Rationale: There are four ventricles in the interior of the brain, which are cavities
filled with CSF produced there. This fluid then circulates into the subarachnoid
space to bathe and float the brain.
Question 6
How is the blood-brain barrier maintained at the cellular level? A) Formed by
microglia phagocytizing general blood circulation particles.
B) Formed by relatively impermeable brain capillaries, due to the glial cells
astrocytes.
C) Formed by ependymal cells lining the choroid plexus of the brain ventricles.
D) Maintained by oligodendrocytes myelinating the capillaries of the central
nervous system.
Correct Answer: B
Rationale: The blood-brain barrier is formed by the relatively impermeable brain
capillaries, due to the glial cells astrocytes wrapping tightly around them.
Question 7
All of the following are functions of the hypothalamus EXCEPT: A) Maintains
homeostasis and regulates hunger, sleep, and thirst
B) Relays sensory impulses to the cerebrum
C) Controls the pituitary gland which regulates hormones of the endocrine system
D) Regulates body temperature and blood pressure
Correct Answer: B
Rationale: The thalamus, not the hypothalamus, serves as the central relay station
for sensory impulses traveling upward to the cerebrum.
