1. What is the primary function of the Golgi tendon organ (GTO)?
A. To detect muscle length and rate of change in length
B. To detect muscle tension and prevent excessive force
C. To detect joint position and movement
D. To detect pain and tissue damage
Correct Answer: B
Rationale: The Golgi tendon organ (GTO) is a proprioceptor located at the
musculotendinous junction. It detects muscle tension and inhibits muscle contraction to
prevent excessive force, a process known as autogenic inhibition .
2. What is the primary function of the muscle spindle?
A. To detect muscle tension and prevent excessive force
B. To detect muscle length and rate of change in length
C. To detect joint position and movement
D. To detect pain and tissue damage
Correct Answer: B
Rationale: The muscle spindle is a proprioceptor that detects muscle length and the
rate of change in length. It triggers the stretch reflex (myotatic reflex) to contract the
muscle to prevent overstretching .
3. What is the stretch reflex (myotatic reflex)?
A. A reflex that causes muscle contraction in response to stretching
B. A reflex that causes muscle relaxation in response to stretching
C. A reflex that causes muscle contraction in response to tension
D. A reflex that causes muscle relaxation in response to tension
,Correct Answer: A
Rationale: The stretch reflex is a monosynaptic reflex that causes muscle contraction in
response to rapid stretching. It is mediated by the muscle spindle and is protective in
nature .
4. What is autogenic inhibition?
A. The relaxation of a muscle in response to tension on the Golgi tendon organ
B. The contraction of a muscle in response to stretching
C. The contraction of a muscle in response to tension
D. The relaxation of a muscle in response to stretching
Correct Answer: A
Rationale: Autogenic inhibition is the relaxation of a muscle in response to tension on
the Golgi tendon organ. It is a protective mechanism that prevents excessive muscle
tension and injury .
5. What is reciprocal inhibition?
A. The relaxation of the antagonist muscle when the agonist contracts
B. The contraction of the antagonist muscle when the agonist relaxes
C. The contraction of both agonist and antagonist muscles
D. The relaxation of both agonist and antagonist muscles
Correct Answer: A
Rationale: Reciprocal inhibition is the relaxation of the antagonist muscle when the
agonist muscle contracts. This is a normal neuromuscular reflex that allows efficient
movement .
6. What is the term for the range of motion around a joint or series of joints?
A. Muscle extensibility
B. Flexibility
C. Mobility
D. Elasticity
Correct Answer: B
Rationale: Flexibility is defined as the range of motion around a joint or series of joints.
It is influenced by muscle extensibility, joint structure, and neural factors .
, 7. What is the difference between active and passive flexibility?
A. Active flexibility uses muscle contraction; passive flexibility uses external force
B. Active flexibility uses external force; passive flexibility uses muscle contraction
C. Active flexibility is static; passive flexibility is dynamic
D. Active flexibility is dynamic; passive flexibility is static
Correct Answer: A
Rationale: Active flexibility refers to the ability to move a joint through its range using
active muscle contraction. Passive flexibility refers to the ability to move a joint through
its range using external force (gravity, body weight, or a partner) .
8. What are the three types of muscle tissue?
A. Skeletal, cardiac, and smooth
B. Skeletal, cardiac, and striated
C. Skeletal, smooth, and voluntary
D. Cardiac, smooth, and voluntary
Correct Answer: A
Rationale: The three types of muscle tissue are skeletal (voluntary), cardiac (involuntary),
and smooth (involuntary). Skeletal muscle is the primary target of stretching and
flexibility training .
9. What is the functional unit of skeletal muscle?
A. Myofibril
B. Sarcomere
C. Muscle fiber
D. Fascicle
Correct Answer: B
Rationale: The sarcomere is the functional unit of skeletal muscle. It is the smallest
contractile unit and extends from Z-line to Z-line .
10. What are the two types of myofilaments within a sarcomere?
A. Actin and myosin
B. Actin and troponin
