Q1: Which of the following best describes the concept of a force couple as it applies to
the shoulder girdle?
A. A single muscle contracting concentrically to produce movement at the shoulder joint.
B. Two or more muscles acting together on different sides of a joint axis to produce the
same rotary motion.
C. The agonist muscle contracting while the antagonist muscle relaxes to allow
movement.
D. A group of muscles that all cross the same joint and perform identical actions.
Correct Answer: B
Rationale: This choice is correct because a force couple involves synergistic muscle
groups working together from different lines of pull to stabilize a joint or create rotation,
such as the serratus anterior and lower trapezius rotating the scapula upward.
Q2: During the concentric phase of a squat, which of the following describes the
arthrokinematic motion occurring at the tibiofemoral joint?
A. The femoral condyles roll anteriorly and glide posteriorly on the tibial plateau.
B. The femoral condyles roll anteriorly and glide anteriorly on the tibial plateau.
C. The femoral condyles roll posteriorly and glide anteriorly on the tibial plateau.
D. The femoral condyles remain stationary while the tibia rotates.
Correct Answer: A
Rationale: This choice is correct because in an open-chain movement (or the knee
flexion/extension component of a squat), the convex femoral condyles roll forward but
must glide backward on the concave tibial plateau to prevent ligamentous impingement.
Q3: According to the length-tension relationship, what occurs when a muscle is
chronically shortened and maintains excessive resting tension?
A. The muscle generates maximal force because it is at its optimal length.
B. The muscle becomes weak and inhibited due to overlapping sarcomeres.
C. The muscle is prone to tearing during eccentric contractions only.
, D. The muscle pulls the origin and insertion points closer together permanently.
Correct Answer: B
Rationale: This choice is correct because when a muscle is shortened and overactive,
the sarcomeres are compressed, which reduces the potential for force production and
alters the muscle's ability to generate tension effectively.
Q4: In the context of lower crossed syndrome, which muscle group acts as the agonist
that is typically overactive and facilitates the anterior pelvic tilt?
A. Gluteus maximus
B. Rectus abdominis
C. Hip flexors (iliopsoas)
D. Hamstrings
Correct Answer: C
Rationale: This choice is correct because the hip flexors, specifically the iliopsoas,
adaptively shorten and pull the pelvis into anterior tilt, directly opposing the weakened
gluteals and abdominals.
Q5: Which of the following best describes altered reciprocal inhibition?
A. The agonist muscle becomes weak due to the tightness of the antagonist muscle.
B. The antagonist muscle becomes weak due to the overactivity of the agonist muscle.
C. Both agonist and antagonist muscles contract simultaneously to stabilize a joint.
D. The agonist muscle contracts forcefully to overcome gravity.
Correct Answer: A
Rationale: This choice is correct because altered reciprocal inhibition occurs when a
tight agonist muscle (like the hip flexor) sends inhibitory signals to the neurologically
opposing antagonist muscle (like the glute), causing it to become weak or underactive.
Q6: When analyzing the mechanics of the foot during the stance phase of gait, what is
the primary action of the tibialis posterior?
A. Dorsiflexion and eversion of the foot.
B. Plantarflexion and inversion of the foot.
C. Plantarflexion and eversion of the foot.
D. Dorsiflexion and inversion of the foot.
Correct Answer: B
Rationale: This choice is correct because the tibialis posterior is a key stabilizer of the
medial longitudinal arch, responsible for plantarflexing and inverting the foot to control
pronation.
Q7: Which muscle is considered a synergistic dominator during a squat when the
gluteus maximus is underactive?
A. Biceps femoris
