Guaranteed | A+ Graded
Exam Instructions
This practice examination is designed to simulate the format and content of the
Portage Learning BIOD 152 Final Exam. The exam covers material from the entire
course, including nervous, cardiovascular, endocrine, urinary, and reproductive
systems.
Number of Questions: 100
Time Allowed: 120 minutes
Format: Multiple choice, true/false, short answer, and diagram labeling
Answer Key & Rationales: Provided after each question
SECTION 1: NERVOUS SYSTEM & ACTION POTENTIALS
Questions 1–25
1. The neuron pictured is best described as:
,A) Bipolar
B) Multipolar
C) Unipolar
D) Pseudounipolar
Answer: A. Bipolar
Rationale: Bipolar neurons have two processes: one dendrite and one axon. They
are often found in sensory pathways such as the retina and olfactory mucosa .
2. Name and describe what is occurring in the neuron cell membrane during
depolarization. Include the charge of the membrane during this phase.
Answer: During depolarization, the sodium gates open and sodium rushes into the
axon. The voltage travels past zero and then on up to +40mV. The inside of the
membrane becomes positively charged compared to the outside .
3. Describe how memories are stored and retrieved in the brain. Include a
specific brain region.
Answer: 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. The involvement of
the limbic system explains why emotionally charged events result in our most
vivid memories .
4. A patient had a CVA in the area indicated by the red x in the figure. What type
of blindness is the patient most likely to incur?
A) Left eye blindness
B) Right eye blindness
C) Bilateral left visual field
D) Bilateral right visual field
,Answer: C. Bilateral left visual field
Rationale: The right optic tract is damaged. All the sensory information from the
left visual fields travels together after the optic chiasm to the right side of the
brain .
5. Label the nerves (A-C) in the figure:
Answer:
• A) Lateral femoral cutaneous
• B) Femoral nerve
• C) Saphenous
6. Which of the following is most likely a symptom of ALS?
A) Impaired ability to swallow
B) Decreased sensation in the hands
C) Shrinkage of cerebral cortex
D) Increased size of brain ventricles
Answer: A. Impaired ability to swallow
Rationale: ALS (Amyotrophic Lateral Sclerosis) primarily affects motor neurons,
leading to muscle weakness and impaired swallowing .
7. What is the purpose of the blood-brain barrier? Describe its maintenance
from a cellular level.
Answer: 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 cell's
, astrocytes. Maintenance of the blood-brain-barrier is important to provide a
stable chemical environment for the nervous system .
8. A patient damaged the radial nerve. What action is most likely limited?
A) Elbow flexion
B) Hip extension
C) Wrist flexion
D) Wrist extension
Answer: D. Wrist extension
Rationale: The radial nerve innervates the muscles responsible for wrist
extension .
9. Which type of sensory receptor responds to stimuli arising outside the body,
such as touch, pressure, or temperature changes?
A) Interceptors
B) Proprioceptors
C) Exteroceptors
D) Nociceptors
Answer: C. Exteroceptors
Rationale: Exteroceptors respond to external stimuli from outside the body,
including touch, pressure, temperature, and pain from the skin surface .
10. A neuron going to the bicep of the forearm is part of the:
A) Central nervous system only
B) Peripheral nervous system only
C) Central nervous system and autonomic nervous system
D) Somatic nervous system
