Portage Learning BIOD 152 Final Exam Study Guide
Complete Review | Practice Questions & Detailed Solutions | 2026/2027 Update
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, and reproductive systems.
Number of Questions: 60
Time Allowed: 90 minutes
Format: Multiple choice (single best answer) and short answer
Answer Key & Rationales: Provided after each question
SECTION 1: NERVOUS SYSTEM & ACTION POTENTIALS
Questions 1–20
1. 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
,Answer: D. Somatic nervous system
Rationale: Neurons controlling skeletal muscles, such as the bicep, are typically
part of the somatic nervous system, a division of the PNS responsible for voluntary
movement. The autonomic system generally controls involuntary functions .
2. This part of a neuron conducts nerve impulses towards the cell body.
A) Axon
B) Dendrites
C) Synaptic terminals
D) Myelin sheath
Answer: B. Dendrites
Rationale: Dendrites receive electrical signals from other neurons and conduct
these impulses toward the neuron's cell body .
3. The neuron pictured below is best described as:
A) Multipolar
B) Bipolar
C) Unipolar
D) Anaxonic
Answer: B. 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 .
4. True or False: Neurons do not physically touch one another.
A) True
B) False
, Answer: A. True
Rationale: Neurons are separated by a synaptic cleft, a small gap through which
neurotransmitters pass to transmit signals chemically rather than through direct
physical contact .
5. An afferent neuron carries information:
A) From the central nervous system to the periphery
B) From the periphery to the central nervous system
C) Between two neurons in the CNS
D) From the autonomic nervous system to muscles
Answer: B. From the periphery to the central nervous system
Rationale: Afferent neurons carry sensory information from sensory receptors
toward the CNS .
6. A postsynaptic neuron would be found:
A) Before the synapse
B) After the synapse
C) Inside the synapse
D) Only in the central nervous system
Answer: B. After the synapse
Rationale: "Postsynaptic" refers to the neuron or cell receiving the signal after the
synaptic cleft .
7. What is the location and function of Satellite cells?
A) CNS - Produce myelin sheath
B) PNS - Regulate environment of neuron cell bodies
