Assess undergraduate students' ability to recall major superficial skeletal muscle groups (head/neck, trunk, upper and lower limbs) and state each muscle's primary action (e.g., flexion, extension, abduction, adduction, rotation, dorsiflexion, plantarflexion). Scope includes common muscles such as deltoid, pectoralis major, latissimus dorsi, biceps brachii, triceps brachii, rectus abdominis, erector spinae, gluteus maximus, quadriceps, hamstrings, gastrocnemius, and tibialis anterior. Easy level; focus on basic identification and single-word primary actions.
