ANTR 350 1st Edition Lecture 16Outline of Last Lecture I. Upper limb jointsII. Clinical correlatesOutline of Current Lecture II. Four main muscle groupsIII. Motions of scapulaIV. Winged scapulaCurrent Lecture-main groups-muscles that move scapula: trapezius, rhomboids, levator scapula, pectoral minor, serratus anterior-muscles that move the arm: lats, pec major, deltoid, teres major, rotator cuff, TB, BB, coracobrachialis-muscles that move the forearm: BB, TB, brachialis, pron tores, pron quad, supinator-muscles that move the hang and fingers: flexors, extensors, and 18 hand muscles-motions of scapula-elevation: shrug-depression: sigh-upward rotation: jumping jack-downward rotation: pull up-protraction: hunching-retraction: squeeze shoulder blades together-winged scapulaThese notes represent a detailed interpretation of the professor’s lecture.
