Human Anatomy Biology 351 Lower Limb Please place your name on the back of the last page of this exam. You must answer all questions on this exam. Because statistics demonstrate that, on average, between 2-5 questions on every 100-point exam are ambiguous enough to come out aberrant on an item analysis, the total number of points possible on this exam is 106. However, grades will be calculated out of a possible 100 points, assuming that 2 3 questions on this exam are aberrant. Section 1: 1. 2. 3. 4. 5. 6. 7. Muscle Identification.
