What are multipennante muscles?

Assistant

Mulitpennate muscles are muscles that have multiple attachments along their length, allowing them to generate more force and control over a wider range of motion compared to single-pennate muscles. They commonly have feather-like structure, with multiple small tendons attaching the muscle fibers onto a central tendon or aponeurosis. This arrangement allows for more precise and diverse movements, as different parts of the muscle can contract independently.

Examples of multipennate muscles in the human body include the deltoid muscle (responsible for shoulder abduction), the rectus femoris muscle in the thigh, and the serratus anterior muscle, which helps control shoulder movement.
