Lecture 10 Pulling Movements Overview Announcements & Schedule Review from Last Week Today's Lecture: Pulling Movements Objectives and Other Readings Bones and Joints: Posterior shoulder, Anterior elbow and wrist Muscles: Trapezius, Latissimus Dorsi, Posterior Deltoid, Biceps Brachii, Brachialis, Brachioradialis, Wrist Flexor/Pronators Exercises: Biceps curl, Vbar row, Lat Pull down, Chin up Announcements Lab Worksheets Module 3 due soon Final Model Test (CORE, Squatting, Hip Hinge, Walk/Run, Pulling and Pushing) Monday Dec. 2. Schedule coming soon. Review Lecture next week with Kahoot’s (Walk/Run, Pushing and Pulling) Course Plan Last Day Pushing Movements Bones and Joints: Anterior shoulder (GH Joint, AC and SC Joints), Posterior elbow (hinge and pivot), wrist (Radiocarpal), and hand Muscles: Pectoralis Major and Minor, Anterior and Lateral Deltoid, Triceps Brachii, Wrist Extensor/Pronators Exercises: Chest Fly, Shoulder Lateral Raise, Triceps Push Downs, and Push Up Objectives 1. Identify the bones and markings of the posterior shoulder, anterior elbow and wrist. 2. Recall the origin, insertion and action of a number of key upper limb muscles (trapezius, latissimus dorsi, posterior deltoid, biceps brachii, brachialis, brachioradialis, wrist flexor/pronators) that act on the shoulder, elbow and wrist. 3. Analyze a number of pulling dominant exercises (biceps curl, cable row, lat pull down, chin up) by identifying the muscles involved; agonist, antagonist and synergist(s) and how they contribute to the movement. Bones and Joints  Posterior Shoulder Girdle Shoulder Joint = Glenohumeral ball and socket Joint Between humeral head and glenoid fossa of scapula, circumducts Scapulothoracic joint (pseudo joint) Learn about AC and SC joints next week  Posterior Scapula Glenoid fossa Spine of scapula (shaft) Acromion process (blade) Superior and Inferior Angle Medial and lateral border Fossa(s) Anterior Scapula Glenoid fossa Coracoid process Coracoid process Intertubercular (bicipital) groove Bicipital Groove Posterior Scapula  Anterior Elbow Elbow Joint = Ulnohumeral (trochlear) hinge Joint Between humerus and ulna, flexion and extension Proximal radioulnar pivot joint, Lateral Medial epicondyle supination and pronation of forearm epicondyle Humerus: Medial and Lateral epicondyles, Condyles: Trochlea and Capitulum Ulna: trochlear notch and coronoid process Coronoid Process Radial tuberosity Radius: Radial tuberosity and Head of radius Anterior Elbow and Wrist  Anterior Wrist and Hand Wrist Joint = Radiocarpal (and ulnocarpal) Condylar Joint Between distal radius and proximal carpals, flexion/extension, radial and ulnar deviation Styloid Process of Radius Proximal Carpals: Scaphoid, Lunate, Triquetrum, Pisiform Distal Carpals Metacarpals Phalanges; Thumb or Pollux has only 2 joints Metacarpal-phalangeal joint (MCP), PIP, DIP joints Proximal row A = Scaphoid Wrist and Hand B = Lunate C = Triquetrum D = Pisiform Distal Row E = Trapezium F = Trapezoid G = Capitate H = Hamate Others 1 = Radius 2 = Ulna 3 = Metacarpal Anterior Elbow and Wrist Muscles Latissimus Dorsi Latissimus Dorsi Trapezius Posterior Deltoid Latissimus Dorsi Thoracolumbar fascia Latissimus Dorsi Extrinsic Origin Insertion Action Exercise of Interest Muscles Latissimus Spinous processes Lower Extends, Lat pull lower thoracic (T6-12) intertubercular adducts and down, row, Dorsi and lumbar (L1-5), (bicipital) medially pull up Sacrum, Iliac crest, groove rotates arm Thoracolumbar fascia at shoulder Trapezius Trapezius Nuchal Ligament Trapezius Ligament on back of neck from occipital bone to the spinous processes of all cervical vertebrae Trapezius Trapezius Extrinsic Origin Insertion Action Exercise of Interest Muscles Trapezius Base of Skull Lateral (distal) Elevates (shrugs) Shoulder Upper (Occipital Bone), third of clavicle Scapula shrug Nuchal Ligament Middle Spinous Acromion process Retracts Scapular processes of C7, (adducts) Scapula Squeezes T1-5 (approx.)
