SECTION 1: ANATOMY & PHYSIOLOGY (Questions 1-25)
Q1: Which energy system provides ATP for high-intensity activities lasting approximately 10-30
seconds, such as a 200-meter sprint?
• A. ATP-PC system
• B. Glycolytic system (anaerobic glycolysis) [CORRECT]
• C. Oxidative system (aerobic)
• D. Beta-oxidation
Correct Answer: B Rationale: The glycolytic system produces ATP rapidly without oxygen and
is the primary energy source for high-intensity activities lasting approximately 30 seconds to 2
minutes. The ATP-PC system (A) fuels activities up to 10 seconds, while the oxidative system
(C) handles longer-duration activities. Beta-oxidation (D) is a fat metabolism process within the
oxidative system.
Q2: Which type of bone is characterized by being thin, flattened, and often curved, serving as
sites for muscle attachment and protection of underlying structures?
• A. Long bones
• B. Short bones
• C. Flat bones [CORRECT]
• D. Irregular bones
Correct Answer: C Rationale: Flat bones, such as the sternum, scapulae, and cranial bones, are
thin, flattened, and often curved. They provide protection for internal organs and extensive
surface area for muscle attachment. Long bones (A) are longer than they are wide (femur,
,2
humerus), short bones (B) are cube-shaped (carpals, tarsals), and irregular bones (D) have
complex shapes (vertebrae, facial bones).
Q3: During a bicep curl, which muscle serves as the antagonist to the biceps brachii?
• A. Brachialis
• B. Brachioradialis
• C. Triceps brachii [CORRECT]
• D. Deltoid
Correct Answer: C Rationale: The triceps brachii is the antagonist to the biceps brachii during
elbow flexion. As the biceps contracts concentrically to flex the elbow, the triceps must lengthen
eccentrically to allow the movement. The brachialis (A) and brachioradialis (B) are synergists
that assist in elbow flexion, while the deltoid (D) primarily performs shoulder abduction.
Q4: Which fiber type is characterized by high oxidative capacity, high mitochondrial density,
and resistance to fatigue?
• A. Type IIx (fast glycolytic)
• B. Type IIa (fast oxidative-glycolytic)
• C. Type I (slow oxidative) [CORRECT]
• D. Type IIb (super-fast twitch)
Correct Answer: C Rationale: Type I fibers (slow oxidative) have high mitochondrial density,
abundant capillaries, and high myoglobin content, making them highly resistant to fatigue and
ideal for endurance activities. Type IIx (A) fibers fatigue rapidly, Type IIa (B) have intermediate
properties, and Type IIb (D) is an outdated classification now referred to as Type IIx in humans.
Q5: Which structure of the neuron receives messages from other cells and transmits them toward
the cell body?
• A. Axon
• B. Dendrite [CORRECT]
• C. Myelin sheath
• D. Axon terminal
,3
Correct Answer: B Rationale: Dendrites are branch-like structures that receive electrochemical
signals from other neurons and transmit these impulses toward the cell body (soma). The axon
(A) transmits signals away from the cell body, the myelin sheath (C) insulates the axon for faster
transmission, and axon terminals (D) release neurotransmitters to communicate with other cells.
Q6: Which chamber of the heart receives oxygenated blood from the lungs via the pulmonary
veins?
• A. Right atrium
• B. Right ventricle
• C. Left atrium [CORRECT]
• D. Left ventricle
Correct Answer: C Rationale: The left atrium receives oxygenated blood returning from the
lungs through the pulmonary veins. This blood then passes through the mitral valve into the left
ventricle (D), which pumps it to the body. The right atrium (A) receives deoxygenated blood
from the body, and the right ventricle (B) pumps blood to the lungs.
Q7: Which respiratory structure contains the vocal cords and serves as the passageway between
the larynx and the bronchi?
• A. Pharynx
• B. Trachea [CORRECT]
• C. Bronchioles
• D. Alveoli
Correct Answer: B Rationale: The trachea (windpipe) is a rigid tube reinforced with C-shaped
cartilage rings that extends from the larynx (which contains the vocal cords) and branches into
the primary bronchi. The pharynx (A) is the throat region above the larynx, bronchioles (C) are
smaller branches within the lungs, and alveoli (D) are the microscopic air sacs where gas
exchange occurs.
Q8: Which joint classification allows movement in one plane (uniaxial) and includes the elbow
and knee joints?
• A. Ball-and-socket (multiaxial)
, 4
• B. Hinge (uniaxial) [CORRECT]
• C. Pivot (uniaxial)
• D. Saddle (biaxial)
Correct Answer: B Rationale: Hinge joints are uniaxial synovial joints that allow flexion and
extension in one plane, exemplified by the elbow (humeroulnar joint) and knee (tibiofemoral
joint). Pivot joints (C) like the atlantoaxial joint also allow uniaxial rotation, while ball-and-
socket joints (A) are multiaxial (shoulder, hip), and saddle joints (D) are biaxial (thumb).
Q9: Which hormone is primarily responsible for increasing blood glucose levels during exercise
by stimulating glycogenolysis and gluconeogenesis?
• A. Insulin
• B. Glucagon [CORRECT]
• C. Cortisol
• D. Growth hormone
Correct Answer: B Rationale: Glucagon, secreted by the alpha cells of the pancreas, raises
blood glucose by stimulating glycogen breakdown (glycogenolysis) and glucose synthesis
(gluconeogenesis) in the liver. Insulin (A) lowers blood glucose, while cortisol (C) and growth
hormone (D) have more complex metabolic effects but are not the primary regulators of acute
blood glucose elevation during exercise.
Q10: Which muscle is considered the prime mover (agonist) during shoulder abduction when
raising the arm laterally to shoulder height?
• A. Pectoralis major
• B. Latissimus dorsi
• C. Deltoid (middle fibers) [CORRECT]
• D. Trapezius (upper fibers)
Correct Answer: C Rationale: The middle fibers of the deltoid are the primary agonist for
shoulder abduction from 0-90 degrees. The supraspinatus initiates the first 15 degrees, and the
trapezius and serratus anterior contribute to upward rotation above 90 degrees. The pectoralis
major (A) performs adduction, the latissimus dorsi (B) performs adduction and extension, and
the upper trapezius (D) primarily elevates and upwardly rotates the scapula.
