E XA M Q U EST I O N S
Q1 QUESTION 1 OF 96
bone
CORRECT ANSWER
hard, dense connective tissue that forms the structural elements of the skeleton, called osseous tissue
RATIONALE
Bone serves as a rigid framework that provides support and protection to vital organs while facilitating movement
through its articulation with muscles. Its composition of osseous tissue, rich in mineral deposits, contributes to its
strength and durability, for maintaining structural integrity in the body.
Q2 QUESTION 2 OF 96
cartilage
CORRECT ANSWER
semi-rigid connective tissue found on the skeleton in areas where flexibility and smooth surfaces support
movement

, RATIONALE
Cartilage serves as a flexible yet supportive connective tissue, providing a smooth surface for joint movement and
structural integrity in the skeleton. Its unique composition, including chondrocytes and extracellular matrix, enables
resilience and reduces friction in articulating surfaces.
Q3 QUESTION 3 OF 96
flat bone
CORRECT ANSWER
thin and curved bone; serves as a point of attachment for muscles and protects internal organs, two layers of
sponge bone sandwiched by compact bone called diploe
Page 3
, RATIONALE
Flat bones are characterized by their thin, curved structure, providing a broad surface area for muscle attachment and
acting as protective barriers for vital organs, with their unique composition of two layers of spongy bone between
compact bone, known as diploe, enhancing strength while minimizing weight. This design exemplifies the
relationship between structure and function in skeletal anatomy.
Q4 QUESTION 4 OF 96
irregular bone
Question illustration
CORRECT ANSWER
bone of complex shape; protects internal organs from compressive forces
RATIONALE
Irregular bones possess complex shapes that enable them to fulfill specific functions, such as protecting internal
organs from compressive forces, which is critical for maintaining structural integrity and supporting the body’s
function. This classification highlights their unique roles in the skeletal system beyond mere support or movement.
Q5 QUESTION 5 OF 96
long bone
Question illustration
CORRECT ANSWER
cylinder-shaped bone that is longer than it is wide; functions as a lever
RATIONALE
A long bone's cylindrical structure maximizes strength and minimizes weight, enabling its primary function as a lever
to facilitate movement and support the body. This shape allows for effective force transmission during activities such
as walking or running.
