Know the differences between a 1st, 2nd and 3rd class levers with regard to the arrangement of the load, fulcrum, and applied force and the characteristics of each (in terms of speed, distance, and force). Which one is most common in our body? Know the functional classifications of muscles into agonists (prime movers), antagonists and synergists and their relationship to one another. Know the terminology for naming muscles based upon their location, origin and insertion, fascicle arrangement, relative position, structural characteristics, action, and other criteria (Table 11- 1). Know the major functions of skeletal muscles in the axial and appendicular divisions. For the following lists of muscles, know the specific characteristics indicated with a “+” for each. For location, you should be able to identify the muscle in a diagram as well as provide a description (e.g., superficial, deep, anterior, posterior, etc). For origins and insertions, unless otherwise indicated, it is sufficient to simply name the bone (as opposed to specific structures on that bone), fascia, or structure (e.g., not specific parts of a structure) .
