EXAM QUESTIONS
QUESTION 1
The study of body structure
CORRECT ANSWER
Anatomy
RATIONALE: The word "Anatomy" comes from the Greek words "anatomein," meaning to cut apart, and "tomos," meaning
a cutting. This etymology highlights the core concept of anatomy, which involves dissecting and examining the internal and
external structures of the body to understand its organization and function.

, QUESTION 2
Study of body function
CORRECT ANSWER
Physiology
RATIONALE: The term "physiology" specifically pertains to the study of the functions and processes that occur within living
organisms, encompassing the intricate workings of the body's systems, organs, and cells. This focus on the body's internal
mechanisms and functions aligns with the definition of the study of body function.
QUESTION 3
Anatomical position
CORRECT ANSWER
RATIONALE: The anatomical position is defined as a standing position with the feet shoulder-width apart and the weight
evenly distributed on both feet, with the palms facing forward and the eyes directed straight ahead. This stance is
considered the standard or reference position for describing human anatomy, allowing for consistent and precise location of
body parts and structures.
QUESTION 4
Superior
CORRECT ANSWER
Towards the head
RATIONALE: The term "superior" refers to a position above or higher than another, in terms of anatomical orientation. In
this context, "Towards the head" is the correct answer because it describes the direction of something being superior,
meaning it is positioned closer to or more towards the top or head of the body, rather than the lower extremities.

, QUESTION 5
Inferior
CORRECT ANSWER
Lower or below
RATIONALE: The term "inferior" generally refers to a position or location that is beneath or below another, emphasizing a
vertical relationship where one is lower than the other. This definition is rooted in the Latin word "inferior," which literally
means "lower" or "below," highlighting the fundamental concept of a lower or secondary status.
QUESTION 6
Medial
CORRECT ANSWER
Toward the midline of the body
RATIONALE: The term "medial" implies a direction or location towards the midline of the body, which is the central or
middle plane that divides the body into left and right sides. This concept is based on the anatomical definition of medial,
where structures or movements are directed towards the body's midline, as opposed to lateral movements which occur
away from the midline.
QUESTION 7
Lateral
CORRECT ANSWER
Towards the side or away from the midline
RATIONALE: The term "lateral" refers to movement or position in relation to the midline of the body, which divides it into
left and right halves. By describing movement "towards the side or away from the midline", the correct answer captures the
essence of lateral movement as it pertains to the body's midline.
QUESTION 8
Proximal
CORRECT ANSWER
Towards or nearest the trunk of the body near the point of origin
RATIONALE: The term "proximal" refers to a point or structure that is closer to the point of origin or the trunk of the body,
which is the central or main part of the body. This concept is used in anatomy to describe the relationship between different
parts of the body, where proximal structures are those that are closer to the trunk, whereas distal structures are those
farther away.

, QUESTION 9
Distal
CORRECT ANSWER
farthest away from trunk of body
RATIONALE: The term "distal" refers to the direction or location further from a central point of reference, in this case, the
trunk of the body. This concept is based on the understanding that the body is divided into proximal (closer to the trunk)
and distal (further from the trunk) parts, allowing for a clear understanding of anatomical relationships and spatial
orientation.
QUESTION 10
Is the elbow more proximal or distal to the forearm
CORRECT ANSWER
Proximal
RATIONALE: The elbow is considered proximal because it is closer to the origin or point of attachment of the major limb,
whereas the forearm is the portion of the limb that extends distally beyond the elbow. This proximal-distal relationship is a
fundamental concept in anatomy, with proximal indicating a structure's position closer to the body's center of origin.
QUESTION 11
Superficial
CORRECT ANSWER
Near the surface
RATIONALE: The word "superficial" originates from the Latin "superficies," meaning surface or skin, indicating that
something is related to the outer layer or surface of an object. By extension, "near the surface" accurately captures the
essence of "superficial" as it implies a focus or attention on the outer layer, rather than delving deeper into inner
complexities or structures.
QUESTION 12
Deep
CORRECT ANSWER
Further away from surface
RATIONALE: The term "Deep" is associated with the concept of vertical direction, where it refers to a location that is at a
greater distance from a surface, particularly the Earth's surface. This meaning is rooted in the understanding that as one
moves further away from the surface, they are essentially moving downwards, which is the definition of being "Deep".
