,Q1 DEMONSTRATE MASTERY OF ANATOMICAL TERMINOLOGY AND HOMEOSTATIC
CONTROL MECHANISMS
A researcher discovers a novel molecule that inhibits the activity of Na+/K+
ATPase in a human cell line. Which of the following immediate effects would be
most directly observed at the cellular level?
A. Increased intracellular Na+ and decreased intracellular K+ concentrations CORRECT
B. Increased resting membrane potential (more negative)
C. Enhanced secondary active transport of glucose into the cell
D. Stabilization of the cell's osmotic balance
RATIONALE: Na+/K+ ATPase actively transports 3 Na+ out and 2 K+ in, maintaining the
electrochemical gradient. Inhibition leads to accumulation of Na+ intracellularly and loss of K+ as
leak channels continue to allow K+ efflux. This disrupts the resting membrane potential (making it
less negative), impairs secondary active transport (which relies on the Na+ gradient), and causes
osmotic swelling due to increased intracellular solute. Thus, only A is correct.
Q2 DEMONSTRATE MASTERY OF ANATOMICAL TERMINOLOGY AND HOMEOSTATIC
CONTROL MECHANISMS
In a histological specimen, a pathologist identifies a tissue with cells that have a
central nucleus, large amounts of extracellular matrix, and no visible striations.
The matrix is firm yet flexible. This tissue is most likely to be found in which of the
following locations?
A. Intervertebral discs
B. External ear CORRECT
C. Tendons
D. Ligaments
RATIONALE: The description matches elastic cartilage, which has chondrocytes in lacunae,
abundant elastic fibers in the matrix, and no striations. It is found in the external ear and
epiglottis. Intervertebral discs (fibrocartilage) have a different matrix composition, tendons and
ligaments are dense connective tissue with fibroblasts, not chondrocytes.

,Q3 DEMONSTRATE MASTERY OF ANATOMICAL TERMINOLOGY AND HOMEOSTATIC
CONTROL MECHANISMS
Which of the following best explains why a deep partial-thickness burn
(second-degree) is typically more painful than a full-thickness burn (third-degree)?
A. Deep partial-thickness burns damage nerve endings, causing them to fire spontaneously
B. Full-thickness burns destroy the nociceptors in the affected area, eliminating pain sensation
CORRECT
C. Deep partial-thickness burns expose the dermis, which has a higher density of pain receptors
than the epidermis
D. Full-thickness burns cause release of endorphins that block pain transmission
RATIONALE: Full-thickness burns destroy the entire epidermis and dermis, including the sensory
nerve endings, so pain is often absent. Deep partial-thickness burns damage the dermis but
leave some nociceptors intact, leading to significant pain. The dermis does have pain receptors,
but the key distinction is the complete destruction of nerve endings in full-thickness burns.
Q4 DEMONSTRATE MASTERY OF ANATOMICAL TERMINOLOGY AND HOMEOSTATIC
CONTROL MECHANISMS
During intramembranous ossification, osteoblasts become entrapped in the matrix
they secrete and differentiate into osteocytes. Which of the following processes is
most directly responsible for the formation of the trabeculae that characterize
spongy bone in this type of ossification?
A. The activity of osteoclasts resorbing bone to create marrow spaces
B. The random entrapment of osteoblasts within the calcifying matrix CORRECT
C. The development of periosteal blood vessels that invade the ossification center
D. The formation of a hyaline cartilage model that later becomes calcified
RATIONALE: In intramembranous ossification, mesenchymal cells condense and differentiate
into osteoblasts, which secrete osteoid. As they calcify, some osteoblasts become trapped in
lacunae and become osteocytes. The irregular network of this calcified matrix forms trabeculae.
Osteoclasts later remodel, but the initial trabecular pattern results from the entrapment process.
A hyaline cartilage model is characteristic of endochondral ossification.

, Q5 DEMONSTRATE MASTERY OF ANATOMICAL TERMINOLOGY AND HOMEOSTATIC
CONTROL MECHANISMS
A patient presents with a fracture of the diaphysis of the femur. Which of the
following describes the correct sequence of events during endochondral bone
healing after the initial hematoma formation?
A. Formation of a fibrocartilaginous callus, then bony callus, then bone remodeling CORRECT
B. Formation of a bony callus, then fibrocartilaginous callus, then bone remodeling
C. Direct deposition of osteoid by osteoblasts without a cartilage intermediate
D. Formation of a hyaline cartilage callus, then a fibrocartilaginous callus, then remodeling
RATIONALE: Fracture healing involves: hematoma, then a fibrocartilaginous callus (formed by
fibroblasts and chondroblasts), then a bony callus (converted to bone via endochondral
ossification), and finally bone remodeling. This sequence is standard for most fractures. Option C
describes intramembranous ossification, which occurs in some stable fractures but not the
general sequence.
Q6 DEMONSTRATE MASTERY OF ANATOMICAL TERMINOLOGY AND HOMEOSTATIC
CONTROL MECHANISMS
Which of the following best explains the functional significance of the glycocalyx
found on the apical surface of epithelial cells?
A. It provides a selective barrier that prevents all molecules from passing through the cell
membrane
B. It mediates cell adhesion to the extracellular matrix and to other cells
C. It increases the surface area for absorption and secretion
D. It acts as a lubricant and protects the cell from mechanical damage CORRECT
RATIONALE: The glycocalyx is a carbohydrate-rich coat on the apical surface of epithelial cells.
It provides lubrication, protection, and cell recognition. It does not prevent all molecules from
passing (the cell membrane is the selective barrier), it is not primarily for adhesion (that is the
function of integrins and cadherins), and it does not increase surface area (that is microvilli).
