Draggable item		Corresponding Item
Gastrocnemius		flexes, abducts, laterally rotates femur
Gluteus maximus		adducts, flexes and medially rotates femur
Rectus femoris		extend femur
Biceps femoris		flexes hip, extends leg at knee
Sartorius		flexes knee; long head helps to extend hip
Tibialis anterior		plantar flexion, flexes knee
Adductor longus		dorsiflexion, inverts foot

Draggable item		Corresponding Item
Pronator Teres		O: anterior surface of ribs 3-5; I: coracoid process
Rhomboid minor		I: upper medial border of scapula; A: elevates and adducts scapula
Triceps brachii		O: T2-T5, I: medial border of scapula
Teres major		O: C7-T1, A: retracts and rotates scapula to rest position
Deltoids		A: extends and adducts arm: I: intertubercle groove of humerus
Biceps brachii		O: acromion, spine of scapula and lateral 1/3 of clavicle, A: abducts, extends and medially & laterally rotates the arm
Latissimus dorsi		O: inferior border of scapula, A: medially rotates and adducts arm
Pectoralis minor		A: extends forearm, I: olecranon process
Rhomboid major		O: supraglenoid tubercle of scapula & coracoid process of scapula, A: Supinates forearm, flexes elbow
Levator scapulae		I: lateral shaft/convexity of radius, A: pronates and flexes forearm
