BIOD 151 - Essential Human Anatomy & Physiology I Final Exam
2026/2027 UPDATE
1. Which anatomical term describes a position towards the front of the body?
A. Posterior
B. Superior
C. Anterior
D. Inferior
Answer: C
Rationale: Anterior (or ventral) refers to the front side of the body, while posterior refers
to the back.
2. What is the primary function of the mitochondria within a cell?
A. ATP production
B. Waste disposal
C. Protein synthesis
D. Genetic storage
Answer: A
Rationale: Mitochondria are the powerhouses of the cell, responsible for generating
adenosine triphosphate (ATP) through aerobic respiration.
,3. Which type of epithelial tissue is found lining the air sacs of the lungs to allow
for rapid gas exchange?
A. Stratified cuboidal
B. Simple squamous
C. Pseudostratified columnar
D. Transitional
Answer: B
Rationale: Simple squamous epithelium consists of a single layer of thin, flat cells, making
it ideal for diffusion and filtration.
4. Which layer of the skin is often referred to as the ‘true skin’ and contains
nerves and blood vessels?
A. Epidermis
B. Hypodermis
C. Dermis
D. Stratum corneum
Answer: C
Rationale: The dermis is located beneath the epidermis and contains connective tissue,
blood vessels, sweat glands, and hair follicles.
5. Which bone cell is responsible for breaking down bone matrix and releasing
minerals back into the blood?
A. Osteoblast
B. Osteocyte
C. Osteoclast
D. Osteogenic cell
Answer: C
Rationale: Osteoclasts are multinucleated cells that resorb (break down) bone tissue,
which is essential for bone remodeling and calcium homeostasis.
, 6. A muscle contraction where the muscle shortens while maintaining constant
tension is called:
A. Isometric
B. Tetanic
C. Isotonic eccentric
D. Isotonic concentric
Answer: D
Rationale: In a concentric isotonic contraction, the muscle length shortens to move a load
while the tension remains constant.
7. Which part of the neuron is responsible for receiving signals from other
neurons?
A. Axon
B. Dendrite
C. Myelin sheath
D. Axon terminal
Answer: B
Rationale: Dendrites are branch-like structures that receive electrochemical messages
from other cells and transmit them to the cell body.
8. The division of the nervous system often referred to as ‘fight or flight’ is the:
A. Parasympathetic nervous system
B. Sympathetic nervous system
C. Somatic nervous system
D. Central nervous system
Answer: B
Rationale: The sympathetic nervous system prepares the body for stressful or emergency
situations.
