Q1 QUESTION 1 OF 26
Which of the following statements is TRUE concerning the function of bones?
CORRECT ANSWER
The carpals are an example of short bones.
Page 1
, RATIONALE
Short bones, such as the carpals, are characterized by their cube-like shape and provide stability and support while allowing for limited
motion, illustrating the diversity of bone types and their specific functions in the skeletal system. This classification highlights the
structural and functional roles that different bone types play in human anatomy.
Q2 QUESTION 2 OF 26
Which of the following statements is FALSE concerning bones?
CORRECT ANSWER
C and D are false: a process is a depression found in a bone and bones are completely smooth surfaces.
RATIONALE
A process refers to a projection or prominence on a bone, highlighting the structural complexity of bone surfaces, while bones typically
exhibit various textures and contours rather than being entirely smooth. Understanding these anatomical features is critical for
recognizing bone morphology and function.
Q3 QUESTION 3 OF 26
Which of the following statements is false about skeletal system?
CORRECT ANSWER
B and D are false: the two main divisions of the skeletal system are: vertebral and thoracic and the vertebral division of the skeleton
is included in the appendicular skeleton
RATIONALE
The skeletal system comprises two main divisions: the axial skeleton, which includes the vertebral column and thoracic cage, and the
appendicular skeleton, encompassing the limbs and girdles. Misclassifying the vertebral division as part of the appendicular skeleton
demonstrates a fundamental misunderstanding of skeletal anatomy.
Q4 QUESTION 4 OF 26
The cranium is formed by ____ bones: the facial skeleton contains ___ bones
CORRECT ANSWER
8: 14
RATIONALE
The cranium consists of eight bones that protect the brain and support the facial structure, while the facial skeleton is composed of
fourteen bones that provide shape and support for the face. Understanding the distinct roles and compositions of cranial and facial bones
is fundamental in anatomy and clinical practice.

What bone is highlight in blue (also designated by the arrow) in the figure below? (superior/internal view)
CORRECT ANSWER
ethmoid bone
RATIONALE
The ethmoid bone, located between the nasal cavity and the orbits, plays a critical role in forming the anterior cranial fossa and
contributing to the structure of the nasal septum. Its distinctive features, such as the cribriform plate and perpendicular plate, are key
identifiers in internal cranial anatomy.
