UPDATED EXAM 100- (VERIFIED ANSWERS).pdf



BIOD 152 Module 2 Practice Exam
Instructions: This practice exam covers the central nervous system, brain anatomy,
spinal cord, reflexes, and peripheral nervous system. Bold italic text highlights key
terms. Each question includes the correct answer and rationale.


SECTION 1: Brain Anatomy and Organization
1. This region of the brain acts to coordinate multiple sources of sensory
information.
• A) Primary sensory cortex
• B) Association area
• C) Motor cortex
• D) Cerebellum
Answer: B) Association area
Rationale: Association areas process and integrate input from multiple sensory
modalities to produce perception and meaningful responses.


2. The _____ fissure separates the cerebrum from the cerebellum.
• A) Longitudinal

, • B) Central
• C) Transverse
• D) Lateral
Answer: C) Transverse
Rationale: The transverse fissure separates the cerebrum from the cerebellum.


3. The _____ fissure separates the right and left cerebral hemispheres.
• A) Median longitudinal
• B) Central
• C) Transverse
• D) Lateral
Answer: A) Median longitudinal
Rationale: The median longitudinal fissure separates the right and left cerebral
hemispheres.


4. This is the most superficial layer of the brain meninges.
• A) Dura mater
• B) Arachnoid mater
• C) Pia mater
• D) Subarachnoid space
Answer: A) Dura mater
Rationale: The dura mater is the toughest, outermost layer of the meninges
protecting the brain and spinal cord.


5. This layer of the meninges is tightly attached to the brain.

, • A) Dura mater
• B) Arachnoid mater
• C) Pia mater
• D) Subdural space
Answer: C) Pia mater
Rationale: The pia mater is the delicate innermost membrane that tightly adheres
to the brain surface.


6. What is the purpose of the blood-brain barrier? Describe its maintenance
from a cellular level.
• A) It prevents all substances from entering the brain; maintained by
neurons
• B) It is a diffusion barrier that prevents most particles from entering CNS
tissue; maintained by astrocytes
• C) It filters blood to produce CSF; maintained by ependymal cells
• D) It provides nutrients to the brain; maintained by oligodendrocytes
Answer: B) It is a diffusion barrier that prevents most particles from entering
CNS tissue; maintained by astrocytes
Rationale: The blood-brain barrier prevents most particles from entering CNS
tissue, keeping the brain and spinal cord separate from general blood circulation.
It is formed by relatively impermeable brain capillaries, due to the glial cells
astrocytes.


7. What is the largest portion of the brain?
• A) Brainstem
• B) Cerebellum

, • C) Cerebrum
• D) Diencephalon
Answer: C) Cerebrum
Rationale: The cerebrum is the largest part of the brain, comprising approximately
83% of brain mass.


8. A patient is having difficulty understanding language but can still speak
fluently. Which area of the brain is most likely damaged?
• A) Broca's area
• B) Wernicke's area
• C) Primary motor cortex
• D) Somatosensory cortex
Answer: B) Wernicke's area
Rationale: Wernicke's area is responsible for language comprehension; damage
leads to fluent but nonsensical speech and poor understanding.


9. A patient is having difficulty producing speech sounds, but other motor
movements are normal. Which area of the brain is most likely damaged?
• A) Broca's area
• B) Wernicke's area
• C) Occipital lobe
• D) Parietal lobe
Answer: A) Broca's area
Rationale: Broca's area controls language expression and directs muscle
movements involved in speech production.
