    Study Notes

    Muscle Structure and Function

    • The belly of a muscle is the main, central part of the muscle where contraction occurs.

    Muscle Nomenclature

    • Muscles are named according to their size, shape, location, and action, with larger muscles often having more descriptive names.

    Muscle Types and Functions

    • An agonist muscle is a muscle that contracts to produce movement, and is responsible for the primary action of the muscle.

    Muscle Movement and Tendons

    • Tendons connect muscles to bones and play a crucial role in muscle movement by transmitting the force of muscle contraction to the bone, resulting in movement.

    Muscle Movement and Fixators

    • Fixators are muscles that stabilize a joint or bone, allowing the agonist muscle to produce movement efficiently and effectively, without interfering with the movement.
