Ivy Tech APHY 101 (Anatomy & Physiology I)
Final Exam 2026/2027 | Latest Verified Questions
and Detailed Answers
OVERVIEW DESCRIPTION:
This comprehensive set of multiple-choice questions is specifically designed for the Ivy
Tech APHY 101 (Anatomy & Physiology I) final exam. Following the department's
guidelines, the questions heavily target the skeletal, muscular, and nervous systems, while
also covering foundational topics in cellular biology, tissues, chemistry, and homeostasis.
Each question includes a correct answer and a concise expert rationale, making this
collection an effective tool for reviewing high-weighting modules and testing overall
comprehension of human body structure and function.
QUESTION 1
Which division of the peripheral nervous system is responsible for carrying sensory
information from the skin and skeletal muscles to the central nervous system?
A) Autonomic nervous system
B) Somatic sensory (afferent) division
C) Visceral sensory division
D) Somatic motor (efferent) division
CORRECT ANSWER: B
EXPERT RATIONALE: The somatic sensory division carries signals from the skin, skeletal
muscles, and joints to the CNS. It is distinct from visceral sensory (organs) and motor
divisions.
QUESTION 2
During skeletal muscle contraction, what is the immediate role of calcium ions (Ca2+)?
,2|Page
A) Hydrolyze ATP to ADP
B) Bind to troponin, moving tropomyosin off actin-binding sites
C) Directly pull actin filaments toward the M-line
D) Open voltage-gated sodium channels at the sarcolemma
CORRECT ANSWER: B
EXPERT RATIONALE: Calcium binds to troponin, causing a conformational change that
shifts tropomyosin away from myosin-binding sites on actin, allowing cross-bridge
formation.
QUESTION 3
Which type of bone tissue contains trabeculae and is typically found at the ends of long
bones?
A) Compact bone
B) Spongy (cancellous) bone
C) Periosteum
D) Cortical bone
CORRECT ANSWER: B
EXPERT RATIONALE: Spongy bone has a porous, lattice-like structure of trabeculae and
is located in epiphyses, reducing weight while providing support.
QUESTION 4
Which brain region is primarily responsible for coordinating precise, voluntary
movements and balance?
A) Cerebrum
B) Thalamus
,3|Page
C) Cerebellum
D) Brainstem
CORRECT ANSWER: C
EXPERT RATIONALE: The cerebellum receives proprioceptive input and motor plans to
fine-tune movement, posture, and balance without initiating conscious motion.
QUESTION 5
What type of epithelial tissue is best suited for diffusion and filtration, found in lung
alveoli and blood vessel endothelium?
A) Stratified squamous
B) Simple cuboidal
C) Simple squamous
D) Transitional
CORRECT ANSWER: C
EXPERT RATIONALE: Simple squamous epithelium is a single layer of flat cells that
minimizes diffusion distance, ideal for gas and solute exchange.
QUESTION 6
Which of the following correctly describes negative feedback in homeostasis?
A) The output enhances the original stimulus, amplifying the change.
B) The output opposes the original stimulus, reducing the initial change.
C) The set point is continuously increased to a new level.
D) It is only involved in blood clotting and childbirth.
CORRECT ANSWER: B
, 4|Page
EXPERT RATIONALE: Negative feedback reverses a deviation from set point, such as
sweating to cool body temperature when overheated.
QUESTION 7
At the neuromuscular junction, what neurotransmitter is released from the motor
neuron to stimulate skeletal muscle?
A) Norepinephrine
B) Dopamine
C) Acetylcholine
D) Serotonin
CORRECT ANSWER: C
EXPERT RATIONALE: Acetylcholine is the only neurotransmitter that binds to nicotinic
receptors on the sarcolemma, generating end-plate potentials and muscle action
potentials.
QUESTION 8
Which cranial bone houses the internal ear structures and contains the mastoid process?
A) Frontal bone
B) Temporal bone
C) Occipital bone
D) Sphenoid bone
CORRECT ANSWER: B
EXPERT RATIONALE: The temporal bone encloses the middle and inner ear and provides
attachment for neck muscles via the mastoid process.
