1 Chapter 10: The Muscular System Objectives: 1. Describe the function of prime movers, antagonists, synergists, and fixators. 2. List the criteria used in naming muscles. Provide an example to illustrate the use of each criterion. 3. Name the common patterns of muscle fascicle arrangement and relate these to power generation. 4. Define lever, and explain how a lever operating at a mechanical advantage differs from one operating at a mechanical disadvantage. 5. Name the three types of lever systems and indicate the arrangement of effort, fulcrum, and load in each. Also note the advantages of each type of lever system. 6. Name and identify the muscles described in Tables 10.1 to State the origin, insertion and action of each. I. Interactions of Skeletal Muscles in the Body A. Skeletal muscles work together or in opposition B. Muscles only pull (never push) C. As muscles shorten, the insertion generally moves toward the origin D. Whatever a muscle (or group of muscles) does, another muscle (or group) undoes E. Muscle Classification: Functional Groups 1. Prime movers a. provide the major force for producing a specific movement 2. Antagonists a. oppose or reverse a particular movement 3. Synergists a. Add force to a movement b. Reduce undesirable or unnecessary movement 4. Fixators a. synergists that immobilize a bone or muscle s origin II. Naming Skeletal Muscles A. Location of muscle 1. bone or body region associated with the muscle B. Shape of muscle 1. deltoid muscle (deltoid = triangle) C. Relative size 1

2 1. maximus (largest) 2. minimus (smallest) 3. longus (long) D. Direction of fibers 1. rectus (fibers run straight) 2. transversus, and oblique (fibers run at angles to an imaginary defined axis) E. Number of origins 1. biceps (two origins) 2. triceps (three origins) F. Location of attachments 1. named according to point of origin or insertion E. Action 1. flexor or extensor, as in the names of muscles that flex or extend, respectively III. Muscle Mechanics: Importance of Fascicle Arrangement and Leverage A. Arrangement of Fascicles 1. Parallel a. fascicles run parallel to the long axis of the muscle b. sartorius 2. Fusiform a. spindle-shaped muscles b. biceps brachii 3. Pennate a. short fascicles that attach obliquely to a central tendon running the length of the muscle b. rectus femoris 4. Convergent a. fascicles converge from a broad origin to a single tendon insertion b. pectoralis major 5. Circular a. fascicles are arranged in concentric rings b. orbicularis oris B. Lever Systems: Bone-Muscle Relationship 1. Lever a. rigid bar that moves on a fulcrum, or fixed point 2. Effort a. force applied to a lever 2

3 3. Load a. resistance moved by the effort C. Lever Systems: Classes 1. First class a. fulcrum is between the load and the effort 2. Second class a. load is between the fulcrum and the effort 3. Third class a. effort is applied between the fulcrum and the load IV. Major Skeletal Muscles of the Body A. Muscles: Name, Action and Innervation 1. Name and description of the muscle a. be alert to information given in the name 2. Origin and insertion a. Origin attachment to the immovable bone b. Insertion attachment to the movable bone c.
