Section 1: Anatomy, Kinesiology, and Biomechanics
1. What is the primary muscle responsible for elbow flexion (e.g., during a
bicep curl)?
A) Triceps Brachii
B) Brachialis
C) Biceps Brachii
D) Brachioradialis
Explanation: While all except the triceps contribute to flexion, the Biceps Brachii
is the prime mover, especially when the forearm is supinated (palms up).
2. The "anatomical position" is defined as:
A) Lying face down
B) Lying face up
C) Standing upright, feet forward, arms at side with palms facing forward
D) A relaxed standing posture
Explanation: This is the standard reference point for all anatomical and
kinesiological descriptions.
3. What type of joint is the shoulder (glenohumeral joint)?
A) Hinge Joint
B) Pivot Joint
C) Ball-and-Socket Joint
D) Saddle Joint
Explanation: The ball (head of humerus) fits into the socket (glenoid fossa of
scapula), allowing for a wide range of motion in all planes.
4. Which of the following is NOT a function of the skeletal system?
A) Hematopoiesis
,B) Mineral Storage
C) Protection of Organs
D) Hormone Production
Explanation: While bones store minerals and protect organs, and red bone marrow
is the site of hematopoiesis (blood cell production), hormone production is
primarily the role of the endocrine system.
5. The term "superior" means:
A) Toward the back of the body
B) Toward the front of the body
C) Toward the head
D) Away from the midline of the body
Explanation: Superior means above, or closer to the head. Inferior means below,
or closer to the feet.
6. Which muscle is a prime mover in horizontal pushing movements like the
bench press?
A) Latissimus Dorsi
B) Posterior Deltoid
C) Pectoralis Major
D) Triceps Brachii
Explanation: The Pectoralis Major is the primary horizontal adductor of the
shoulder, making it the main mover in exercises like bench press and push-ups.
7. What is the role of a "synergist" muscle?
A) It is the primary muscle responsible for a movement.
B) It opposes or reverses a movement.
C) It assists the prime mover and helps prevent unwanted movements.
D) It stabilizes the origin of the prime mover.
Explanation: Synergists assist agonists (prime movers) and fine-tune the
movement.
8. The term "proximal" refers to a location that is:
A) Farther from the point of attachment
B) Closer to the point of attachment
C) Toward the midline of the body
, D) Away from the midline of the body
Explanation: Proximal means closer to the trunk or point of origin (e.g., the
shoulder is proximal to the elbow). Distal means farther away.
9. What plane of motion does a squat primarily occur in?
A) Transverse Plane
B) Frontal Plane
C) Sagittal Plane
D) Coronal Plane
Explanation: Flexion and extension movements, like bending and straightening the
knees and hips in a squat, occur in the sagittal plane.
10. Which of the following is a hinge joint?
A) Hip
B) Shoulder
C) Saddle Joint of the Thumb
D) Elbow
Explanation: The elbow joint allows motion primarily in one plane (flexion and
extension), classifying it as a hinge joint.
Section 2: Exercise Physiology
11. What is the primary energy system used during a 400-meter sprint?
A) ATP-PC System
B) Glycolytic (Lactic Acid) System
C) Oxidative System
D) Beta-Oxidation
*Explanation: The 400m sprint, lasting about 45-60 seconds, relies heavily on
anaerobic glycolysis for ATP production, leading to lactate accumulation.*
12. The SA (Sinoatrial) Node is often called the:
A) Ventricular Pacer
B) Atrial Regulator
C) Pacemaker of the Heart
D) Cardiac Output Center
