  7. Naming of Skeletal Muscles 1. Direction of muscle fibers 2. Relative size of the muscle 3. Many muscles are named for bones 4. Number of origins 5. Location of the muscle’s origin and insertion 6. Shape of the muscle 7. Action of the muscle

  8. 5 Golden Rules of Skeletal Muscle 1). All muscles cross at least one joint 2). The bulk of the muscle lies proximal to the joint 3). Two attachments: origin and insertion 4). Muscles pull 5). The insertion moves toward the origin
