For maximum tension and hence torque generation across a joint, some muscles are more reliant on muscle length, whereas other muscles are more dependent on the perpendicular distance from the tendon insertion to the axis of rotation.

Question

Quizplus · Accepted Answer

Muscles generate tension and torque based on both their length (due to the length-tension relationship) and the perpendicular distance from the tendon insertion to the axis of rotation (due to leverage principles). Different muscles may rely more on one factor than the other depending on their anatomical configuration and the specific function they perform.
