Q1 QUESTION 1 OF 90
adipocytes
CORRECT ANSWER
lipid storage cells
RATIONALE
Adipocytes function primarily as lipid storage cells, accumulating triglycerides to provide energy reserves and insulation. Their
role in energy homeostasis and metabolic regulation underscores their importance in maintaining physiological balance.
Q2 QUESTION 2 OF 90
anchoring junction
CORRECT ANSWER
mechanically attaches adjacent cells to each other or to the basement membrane
RATIONALE
Anchoring junctions provide structural stability by linking the cytoskeletons of adjacent cells or connecting them to the
extracellular matrix, thereby maintaining tissue integrity and resistance to mechanical stress. This function is critical in tissues
subjected to stretching or shear forces, such as epithelial and cardiac tissues.
Q3 QUESTION 3 OF 90
apical
CORRECT ANSWER
that part of a cell or tissue which, in general, faces an open space
Page 2
, RATIONALE
Apical refers to the surface of epithelial cells that is oriented toward the lumen or external environment, facilitating processes
such as absorption and secretion. This orientation is crucial for maintaining the functional polarity of tissues, allowing for
specialized interactions with the surrounding environment.
Q4 QUESTION 4 OF 90
apoptosis
CORRECT ANSWER
programmed cell death
RATIONALE
Programmed cell death, or apoptosis, is a highly regulated process that eliminates damaged or unnecessary cells without
causing inflammation, maintaining tissue homeostasis. This biological mechanism is essential for development, immune
function, and the prevention of cancer by regulating cell proliferation.
Q5 QUESTION 5 OF 90
basal lamina
CORRECT ANSWER
thin extracellular layer that lies underneath epithelial cells and separates them from other tissues
RATIONALE
Basal lamina functions as a selective barrier, providing structural support to epithelial tissues while facilitating the exchange of
nutrients and signaling molecules between the epithelium and underlying connective tissue. This thin extracellular matrix is
integral to tissue organization, influencing cell behavior and tissue regeneration.
Q6 QUESTION 6 OF 90
basement membrane
CORRECT ANSWER
in epithelial tissue, a thin layer of fibrous material that anchors the epithelial tissue to the underlying connective tissue;
made up of the basal lamina and reticular lamina
Page 3
, RATIONALE
The basement membrane serves as a structural foundation for epithelial tissues, facilitating attachment to underlying connective
tissue while providing a selective barrier for nutrient exchange. Composed of the basal lamina and reticular lamina, it plays a
critical role in tissue organization and integrity.
Q7 QUESTION 7 OF 90
chondrocytes
CORRECT ANSWER
cells of the cartilage
RATIONALE
Chondrocytes are specialized cells that produce and maintain the extracellular matrix of cartilage, playing a critical role in its
growth and repair. Understanding their function is essential for comprehending cartilage physiology and pathology.
Q8 QUESTION 8 OF 90
clotting
CORRECT ANSWER
also called coagulation; complex process by which blood components form a plug to stop bleeding
RATIONALE
Coagulation refers to the intricate biochemical cascade that leads to the formation of a fibrin clot, essential for hemostasis and
preventing excessive blood loss. This process involves platelets and various clotting factors that work in concert to stabilize the
initial platelet plug.
Q9 QUESTION 9 OF 90
endothelium
CORRECT ANSWER
tissue that lines vessels of the lymphatic and cardiovascular system, made up of a simple squamous epithelium
