BONUS QUESTION!!! Below are the 6-steps to the motor control analysis of simple joint motions.  Perform this analysis on the knee joint only going from position A (in the air) to position B (landing in a squat).   Step 1: Joint name and position/movement Step 2: Effect of external force on the joint  Step 3: Type of muscle contraction  Step 4: Plane of movement and axis of rotation Step 5: Position of muscles relative to the joint Step 6: Muscle names   Step 1: Tibiofemoral flexion Step 2: Tibiofemoral flexion (as the body falls, the knee would collapse into a flexed position if no muscles were acting) Step 3: Eccentric (since 1 and 2 are opposite AND since this is a controlled flexion–the muscles are decelerating the fall) Step 4: Sagittal motion about the frontal-horizontal axis Step 5: Muscles would be lengthening ANTERIOR to the knee joint Step 6: Quadriceps (VLO, VMO, vastus intermedius, rectus femoris)   **You can earn 1 bonus point for this question if you get it ENTIRELY correct.  No partial credit will be applied for THIS question.**

Name the two muscles that make up the iliopsoas and give their respective origins, insertions, and actions.  When naming an action, make sure you specify where the action occurs (which joint). Iliacus O: iliac fossa I: lesser trochanter of the femur A: hip flexion, ER Psoas major O: lateral bodies of the lumbar vertebrae I: lesser trochanter of the femur A: hip flexion, ER *This was the minimum necessary for full credit.  If you listed hip adduction, that could also be a secondary action.  If you gave more detailed origins/insertions, as long as they were correct…all good.
