,Section 1: Anatomy and Kinesiology (Q1-Q30)
Q1: Which plane of motion is vertical, extends side to side, and divides the body into anterior and posterior portions?
A. Sagittal Plane
B. Frontal Plane [CORRECT]
C. Transverse Plane
D. Coronal Plane
Correct Answer: B
Rationale: The Frontal Plane is vertical, extends side to side, and divides the body into anterior (front) and posterior (back)
portions. Movement along the frontal plane occurs along the sagittal axis and includes abduction and adduction. The Sagittal Plane
divides the body into right and left portions. The Transverse Plane is horizontal and divides the body into upper and lower portions.
Coronal is another name for the Frontal Plane, making it a duplicate, not a distinct answer.
Q2: In which plane do flexion and extension movements primarily occur?
A. Frontal Plane
B. Transverse Plane
C. Sagittal Plane [CORRECT]
D. Horizontal Plane
Correct Answer: C
Rationale: Flexion and extension are movements that occur primarily in the Sagittal Plane, which is vertical and extends front to
back, dividing the body into right and left portions. Examples include bicep curls and knee extensions. The Frontal Plane involves
abduction/adduction. The Transverse (Horizontal) Plane involves rotational movements.
Q3: A first-class lever has which arrangement of its three components?
A. Fulcrum between effort and resistance [CORRECT]
B. Resistance between fulcrum and effort
C. Effort between fulcrum and resistance
D. Fulcrum at the end of the lever
Correct Answer: A
Rationale: A first-class lever places the fulcrum between the effort and the resistance, like a seesaw. An example in the body is the
atlanto-occipital joint during head nodding. A second-class lever has resistance between fulcrum and effort (wheelbarrow). A
third-class lever has effort between fulcrum and resistance, which is the most common lever type in the human body.
Q4: Which type of joint is found at the shoulder and hip, allowing movement in multiple planes including flexion,
extension, abduction, adduction, rotation, and circumduction?
A. Hinge joint
B. Pivot joint
C. Condyloid joint
D. Ball and socket joint [CORRECT]
Correct Answer: D
Rationale: Ball and socket joints at the shoulder and hip allow the greatest range of motion, including flexion, extension,
hyperextension, circumduction, rotation (medial and lateral), abduction, and adduction. Hinge joints (knee, elbow) allow only
flexion and extension. Pivot joints allow rotation only. Condyloid joints (wrist) allow flexion, extension, abduction, adduction, and
circumduction but not rotation.
,Q5: Which connective tissue attaches bone to bone at movable joints and helps protect the joint from dislocation?
A. Tendons
B. Fascia
C. Ligaments [CORRECT]
D. Cartilage
Correct Answer: C
Rationale: Ligaments are dense, regular connective tissue that attaches bone to bone at movable joints and provides stability by
limiting excessive or abnormal movement. Tendons connect muscle to bone, not bone to bone. Fascia is a sheet of connective tissue
that encloses muscles. Cartilage provides cushioning at joint surfaces but does not connect bones directly.
Q6: What is the function of tendons in the musculoskeletal system?
A. To connect bone to bone at joints
B. To connect muscle to bone [CORRECT]
C. To store calcium and minerals
D. To produce red blood cells
Correct Answer: B
Rationale: Tendons connect muscle to bone, transmitting the force of muscle contraction to the skeletal system to produce movement.
Ligaments connect bone to bone. Calcium storage and red blood cell production are functions of bone tissue, not tendons.
Q7: Which region of the spine consists of 12 vertebrae located behind the rib cage?
A. Cervical
B. Thoracic [CORRECT]
C. Lumbar
D. Sacral
Correct Answer: B
Rationale: The thoracic spine consists of 12 vertebrae (T1-T12) located behind the rib cage, providing attachment points for the
ribs and allowing limited flexion, extension, and rotation. The cervical spine has 7 vertebrae in the neck. The lumbar spine has 5
vertebrae in the lower back. The sacrum consists of 5 fused vertebrae below the lumbar spine.
Q8: What term describes a lateral curvature of the spine?
A. Lordosis
B. Kyphosis
C. Scoliosis [CORRECT]
D. Spondylolisthesis
Correct Answer: C
Rationale: Scoliosis is a lateral (sideways) curvature of the spine, often appearing as an S- or C-shape when viewed from behind.
Lordosis is an excessive inward curve of the lumbar spine (swayback). Kyphosis is an excessive outward curve of the thoracic spine
(hunchback). Spondylolisthesis is the forward slippage of one vertebra on another.
Q9: Which type of muscle tissue is found in the walls of hollow organs and blood vessels and is under involuntary
control?
A. Skeletal muscle
B. Cardiac muscle
C. Visceral (smooth) muscle [CORRECT]
, D. All of the above
Correct Answer: C
Rationale: Visceral or smooth muscle is found in the walls of hollow organs (intestines, stomach, blood vessels) and operates under
involuntary control of the autonomic nervous system. Skeletal muscle is voluntary and attached to bones. Cardiac muscle is found
only in the heart. While cardiac muscle is also involuntary, the question specifically asks about muscle in hollow organs and blood
vessels.
Q10: During concentric muscle action, what occurs?
A. The muscle lengthens while producing tension
B. The muscle shortens while producing tension [CORRECT]
C. The muscle produces tension without changing length
D. The muscle produces no tension at all
Correct Answer: B
Rationale: During a concentric muscle action, the muscle shortens while generating tension, such as the bicep shortening during the
lifting phase of a bicep curl. Eccentric action involves the muscle lengthening under tension (lowering phase). Isometric action
involves tension production without a change in muscle length (holding a static position).
Q11: Which lever type is most common in the human body?
A. First-class lever
B. Second-class lever
C. Third-class lever [CORRECT]
D. Fourth-class lever
Correct Answer: C
Rationale: Third-class levers, where the effort is between the fulcrum and the resistance, are the most common in the human body.
Most joints involving muscle attachments operate as third-class levers because the muscle insertion (effort) is between the joint
(fulcrum) and the distal end of the limb (resistance). First-class levers are rare; second-class levers are also uncommon in the body.
Q12: What movements occur at a hinge joint?
A. Flexion, extension, and rotation
B. Abduction, adduction, and circumduction
C. Flexion and extension only [CORRECT]
D. Supination and pronation only
Correct Answer: C
Rationale: Hinge joints such as the knee and elbow primarily allow flexion and extension movements in the sagittal plane. The
ankle, also considered a modified hinge joint, additionally allows plantar flexion and dorsiflexion. Rotation is not permitted at true
hinge joints. Abduction, adduction, and circumduction occur at ball and socket or condyloid joints.
Q13: Where is the body's center of gravity approximately located?
A. At the sternum
B. At the top of the head
C. At the level of the navel (belly button) [CORRECT]
D. At the knees
Correct Answer: C
Rationale: The body's center of gravity, the point at which all force movements are in equilibrium, is located approximately at the
level of the navel (belly button) in a standing anatomical position. In water, the center of buoyancy is located at the sternum, which
