SHOW ALL QUESTIONS
A pennate or pinnate muscle (also called a penniform muscle) is a type of skeletal muscle with fascicles that attach obliquely (in a slanting position) to its tendon. This type of muscle generally allows higher force production but a smaller range of motion.[1][2] When a muscle contracts and shortens, the pennation angle increases.[3]
