Q1.
A cell placed in a solution swells and eventually lyses. Which best describes the tonicity
of the solution and the direction of net water movement?
A. Hypertonic; water moves out of the cell B. Hypotonic; water moves into the cell
C. Isotonic; no net water movement D. Hypertonic; water moves into the cell
Correct: B - Hypotonic; water moves into the cell
Rationale:In a hypotonic solution, solute concentration outside the cell is lower than inside,
so water moves by osmosis into the cell, causing swelling and lysis. Hypertonic solutions
cause shrinkage; isotonic solutions produce no net movement.
Why the other answers are wrong:
A. Hypertonic solutions cause water to leave the cell, leading to crenation, not lysis.
C. Isotonic solutions result in no net water movement, so the cell would not swell and lyse.
D. In hypertonic solutions, water moves out of the cell, not into it.

Q2.
During a histology lab, a student observes a tissue with tightly packed cells, apical
microvilli, and a basement membrane. Which primary tissue type is this?
A. Connective tissue B. Muscle tissue
C. Epithelial tissue D. Nervous tissue
Correct: C - Epithelial tissue
Rationale:Epithelial tissue is characterized by closely packed cells, apical specializations like
microvilli, and a basement membrane. Connective tissue has abundant extracellular matrix;
muscle and nervous tissues have distinct cellular features.
Why the other answers are wrong:
A. Connective tissue is defined by sparse cells and abundant extracellular matrix, not tightly
packed cells with microvilli.
B. Muscle tissue consists of elongated contractile cells, not tightly packed cells with microvilli.
D. Nervous tissue is composed of neurons and glial cells with processes, not tightly packed
cells with apical microvilli.

Q3.
A patient reports severe sunburn with blistering after prolonged sun exposure. Which
epidermal layer has been primarily damaged to cause blistering?
A. Stratum corneum B. Stratum basale
C. Stratum granulosum D. Stratum spinosum
Correct: D - Stratum spinosum
Rationale:Blistering occurs when the stratum spinosum is damaged, as its desmosomes hold
cells together; separation here creates a blister. The stratum corneum is dead and outermost,
the basale is deepest, and the granulosum is a transitional layer.
Why the other answers are wrong:
A. The stratum corneum is composed of dead keratinized cells and does not cause blistering
when damaged alone.
B. The stratum basale is the deepest layer and its damage would affect regeneration, but
blistering is not its primary feature.
C. The stratum granulosum is a thin layer where keratinization begins, not the primary site for
blister formation.

Q4.
Which bone marking is correctly paired with its function?
A. Foramen - a depression on a bone B. Condyle - a rounded articular projection
surface
C. Tuberosity - a narrow slit-like opening D. Fossa - a sharp, slender projection
Correct: B - Condyle - a rounded articular projection
Rationale:A condyle is a rounded articular projection that forms joints. A foramen is an
opening, a tuberosity is a rounded prominence, and a fossa is a shallow depression.
Why the other answers are wrong:
A. A foramen is an opening or hole through which vessels and nerves pass, not a depression.
C. A tuberosity is a rounded prominence for muscle attachment, not a slit-like opening.
D. A fossa is a shallow depression, not a sharp projection.
Reference: Marieb, E.N. & Hoehn, K. (2023). Human Anatomy & Physiology, 12th Ed., Ch. 6
Q5.
A muscle biopsy reveals a high density of mitochondria and myoglobin. Which fiber type
is most likely predominant, and what functional advantage does it provide?
