    Study Notes

    Muscle Structure and Function

    • Tearing and separation of the gastrocnemius muscle's tendon of insertion would most seriously impair an animal's ability to stand on the affected limb.

    Muscle Contraction

    • The contraction of a muscle usually displaces the tendon of insertion.

    Muscle Tissue

    • The endomysium is located between muscle fibers, surrounding each fiber.

    Muscle Origin and Insertion

    • The origin of a muscle is usually proximal and stable, while the insertion is usually distal and movable.

    Triceps Brachii

    • The triceps brachii performs elbow extension (straightening the arm).
