The Golgi tendon organ (GTO) responds to:
Answer: Changes in muscle tension or force
GTOs are tension-sensitive proprioceptors located at the musculotendinous junction that respond to excessive force to protect the muscle and tendon.
Which type of muscle contraction occurs when the muscle generates force while lengthening?
Answer: Eccentric contraction
Eccentric contraction produces force while the muscle lengthens, common in activities like lowering a weight or walking downhill.
Which scapular movement elevates the acromion and is required for full overhead arm reach?
Answer: Scapular upward rotation
Scapular upward rotation tilts the glenoid fossa superiorly, allowing full shoulder abduction and flexion above 90 degrees.
A 'valgus' deformity at the knee means the tibia deviates:
Answer: Laterally (away from the midline), creating knock-knees
Genu valgum (knock-knee) describes lateral deviation of the tibia relative to the femur, so knees angle inward.
Which muscle is the primary mover for cervical rotation to the right?
Answer: Left sternocleidomastoid and right splenius capitis
Cervical rotation to the right is produced by the left SCM pulling the chin right and the right splenius capitis rotating the head right from behind.
The 'Q angle' is a measurement used to assess:
Answer: The alignment of the quadriceps pull relative to the patella and tibial tuberosity
The Q angle measures the angle between the quadriceps pull (ASIS to patella) and the patellar tendon (patella to tibial tuberosity), indicating patellar tracking stress.
During the swing phase of gait, the primary role of the hip flexors is to:
Answer: Advance the limb forward through hip flexion
During swing phase, the hip flexors (primarily iliopsoas) actively flex the hip to advance the lower limb forward for the next step.
