3. Beginning in a seated position with feet flat on the floor, describe the movements needed to stand up (do not include the ankle). (see Muscles that move the Thigh and Leg; Lab manual pg. 278-284) Articulation 1 (Joint) where movement occurs: Movement that occurs: Muscle(s) (or group) required for movement: Innervation of the involved muscles: Articulation 2 (Joint) where movement occurs: Movement that occurs: Muscle(s) (or group) required for movement: Innervation of the involved muscles: 4. Beginning in an upright standing position, with your humerus in anatomical position, elbows flexed, forearms pronated and palms flat on a wall, describe the movements necessary to push yourself away from the wall. Or if it's easier, just do a push-up and describe the concentric phase as you push yourself from the floor back to starting position (see Muscles that move the Wrist, Hand, and Digits; pg. 273-277, and Muscles that move the Pectoral Girdle and Forearm; Lab manual pg. 270-273) Articulation 1 (Joint) where movement occurs: Movement that occurs: extension of the elbow Muscle(s) (or group) required for movement: Anconeus Innervation of the involved muscles: radial nerve Articulation 2 (Joint) where movement occurs: Movement that occurs: mover of the scapula in protraction Muscle(s) (or group) required for movement: Serratus anterior Innervation of the involved muscles: long thoracic nerve Articulation 3 (Joint) where movement occurs: Movement that occurs: supinates forearm Muscle(s) (or group) required for movement: Supinator Innervation of the involved muscles: deep radial nerve
