Which type of muscle contraction produces the most force?
Answer: Eccentric
Eccentric contractions produce the greatest force because cross-bridge cycling is supplemented by passive titin and connective tissue tension.
The popliteus muscle performs which unique function at the knee joint?
Answer: Unlocks the knee by internally rotating the tibia
The popliteus 'unlocks' the fully extended (screw-home) knee by internally rotating the tibia to allow flexion to begin.
Which connective tissue structure directly connects bone to bone?
Answer: Ligament
Ligaments are dense connective tissue structures that connect bone to bone and provide joint stability.
In anatomical position, the term 'supine' refers to:
Answer: Lying face up
Supine means lying on the back with the face and anterior surface facing upward.
Which muscle is NOT part of the quadriceps group?
Answer: Sartorius
The sartorius is a separate muscle that crosses both the hip and knee, and is not considered part of the quadriceps group.
The term 'origin' in muscle anatomy refers to:
Answer: The proximal, more stationary bony attachment
The muscle origin is the proximal, more stationary attachment point, while the insertion is the distal, more movable attachment.
Which muscle is the prime mover for plantarflexion of the ankle during push-off in gait?
Answer: Gastrocnemius
The gastrocnemius is the most powerful plantarflexor and generates the propulsive force during push-off in the gait cycle.
