Assess students' ability to recall and identify major human skeletal muscle groups (e.g., deltoids, pectorals, biceps, triceps, trapezius, latissimus dorsi, abdominals, gluteals, quadriceps, hamstrings, gastrocnemius), locate them on a simple body diagram, and state each group's primary movement(s) (e.g., elbow flexion, shoulder abduction, knee extension). Scope: Grade 6–8, moderate difficulty, focus on naming and matching muscles to their principal actions.
