Human Anatomy: Muscles of the Body

Human Anatomy: Chapter 11 - Muscles of the Body

Mechanics of Muscle Function

• Skeletal Muscles
    - Attach to the bony skeleton.
    - Produce movements.

• Physical Parameters that define muscle action on the skeleton:
    - Fascicle arrangement within a muscle.
    - Principles of lever mechanics.
    - Position of a muscle as it crosses a joint.

Arrangement of Fascicles in Muscles (1 of 4)

• Skeletal muscles consist of fascicles:
    - Fascicles: bundles of muscle fibers.
    - Arrangement tells about the action of the muscle.
