Anatomy of the shoulder joint is discussed in detail in this video. Responsible for the movement of our ever-important hands, the shoulder is an extremely important part of the body when it comes to getting done what it is we want to get done. The anatomy of the shoulder consists of the shoulder joint and shoulder girdle. Recent research findings are incorporated in this review of the functional anatomy of the shoulder complex. Movements of the human shoulder represent the result of a complex dynamic interplay of structural bony anatomy and biomechanics, static ligamentous and tendinous restraints, and dynamic muscle forces. Relevant anatomical structures for these conditions can easily be identified and demonstrated by cross examination by instructors and participants. The shoulder is comprised of four distinct joints and is the foundation of movement for the arms (Neumann, 2010): The sternoclavicular (SC) joint, where the proximal end of the clavicle floats on the sternum and first rib, is a relatively small joint that connects the shoulder and arm directly to the rib cage of the axial skeleton. the joint and can thereby produce increased speed of movement, although at a sacrifice of force. The glenohumeral joint is where the ball (humeral head) and the socket (the glenoid) meet. applied anatomy of shoulder joint 1. This mobility provides the upper extremity with tremendous range of motion such as adduction, abduction, flexion, extension, internal rotation, external rotation, and 360° circumduction in the sagittal plane. The force arm must be smaller than the resistance arm, and the applied force lies closer to the axis than the resistance force. Gross Anatomy. site where most movements of the shoulder girdle occur; B. Here we explain the basic anatomy of the shoulder. Applied anatomy of the sacroiliac joint. The shoulder joint is a ball and socket joint between the scapula and the humerus.However the socket of the glenoid cavity of the scapula is itself quite shallow and is made deeper by the addition of the glenoid labrum.The glenoid labrum is a ring of cartilaginous fibre attached to the circumference of the cavity. General Anatomy. This ring is continuous with the tendon of the biceps brachii above. While each of these is an independent entity, capable of independent motion, all contribute their share to the total in the normal functional mechanism of the extremity. The elbow patients herein discussed feature common soft tissue conditions such as tennis elbow, golfers' elbow and olecranon bursitis. Disorders of the sacroiliac joint 44. Clinical examination of the sacroiliac joint 42. how many planes of motion can the shoulder move in? The shoulder joint complex is composed of four independent articulations,-the sternoclavicular, acromioclavicular, scapulothoracic, and glenohumeral joints. Section 11: The sacroiliac joint and coccyx ONLINE Applied anatomy of the sacroiliac joint 41. The shoulder complex, together with other joint and muscle mechanisms of the upper limb, primarily is concerned with the ability to place and control the position of the hand in the visual work space in front of the body. what 4 articulations are involved with the shoulder joint? Glenohumeral joint (Articulatio glenohumeralis) The glenohumeral, or shoulder, joint is a synovial joint that attaches the upper limb to the axial skeleton. APPLIED ANATOMY OF SHOULDER COMPLEX 2. The Anatomy of the Shoulder. PLAY. The bones of the shoulder are: the clavicle; the scapula; the humerus; Test your knowledge of the clavicle, scapula and humerus with our labeled diagram exercises and quizzes! Find out in this Anatomy of the Shoulder Quiz. Pages e233-e238. The Scapulothoracic joint is also known as a "physiological" joint because it has a functional movement but there is no biological bone to bone contact.. its an articulation between the subscapular fossa of the scapula and the thoracic wall poonam.kdc@gmail.com. Patients usually … To give the necessary support and security, the band-like ligaments uniting the bones are strong and the extent of the movements is restricted. The shoulder is made up of two joints, the acromioclavicular joint and the glenohumeral joint.

The shoulder complex, together with other joint and muscle mechanisms of the upper limb, primarily is concerned with the ability to place and control the position of the hand in the visual work space in front of the body. Overall it provides the learner with an applied practical understanding of anatomy which is important to ensure technical competence and safety. The shoulder allows overhead activities like screwing in a lightbulb and provides the strength to do a handstand or throw a 95-mile per hour fastball. APPLIED ANATOMY • Movement of the shoulder is critical to maintain the positioning of the humeral head relative to the glenoid. The scope of the course includes bones, joints, muscles, tendons and ligaments, as well as other tissues related to the musculoskeletal system such as fascia, cartilage, bursae and retinacula. sternum, clavicle, ribs, scapula, humerus. The unique anatomy of the shoulder enables the greatest range of motion of any joint in the body. [Article in German] Roos H(1), Brugger S.

[Functional and applied anatomy of the shoulder joint of the domestic cat]. Kinesiology and Applied Anatomy . The acromioclavicular joint is where the acromion, part of the shoulder blade (scapula) and the collar bone (clavicle) meet. Applied anatomy- Shoulder joint structure, function, dysfunction. Acromioclavicular Joint The acromioclavicular joint is formed by an articulation between the lateral end of the clavicle and the acromion of the scapula (Figures 1–3, additional material). 67. The glenohumeral joint is a multiaxial synovial ball and socket joint that functions as a diarthrosis to facilitate a wide range of motion for the upper extremity ( 2 ). Extension: 0 to 10º above horizontal plane. The scapulothoracic mechanism is described, including a review of scapular motion and the structure and function of the sternoclavicular and acromioclavicular joints. The shoulder is a complex joint with high mobility but a lack of stability. Learn vocabulary, terms, and more with flashcards, games, and other study tools. J. When nerve injury occurs at the level of the spinoglenoid notch, a painless weakness of external rotation and atrophy of the infraspinatus will occur. The human shoulder is an amazing machine. What can you tell us about how these joints work? Bones. Joint goniometry is presented. The Sternoclavicular joint is the articulation between the sternum and the clavicle.

The joint with the greatest range of motion is the ball-and-socket joint. Also available from Amazon: Applied anatomy: The construction of the human body. The humerus is the bone of the arm that articulates with the scapula proximally and with the radius and the ulna distally. Amputation At The Shoulder-Joint The many different methods of amputating at the shoulder may for our purposes be divided into two classes, - the flap method and the racket method. The hip joint and the glenohumeral (shoulder) joint are the only ball-and-socket joints of the body. Anatomical Terminology The course emphasizes the role and nature of … Body Planes Start studying 4. applied anatomy of shoulder joints. Interpretation of the clinical examination of the sacroiliac joint and coccyx 43. A. Shoulder anatomy and biomechanics, particularly those of the rotator cuff (RC), endow the glenohumeral joint with dynamic and static stability throughout a substantial range of motion. Shoulder motion requires the coordinated effort of muscles, tendons, ligaments, and bones primarily across the glenohumeral joint and scapulothoracic articulation . 3 planes of motion. For example, the joint surfaces of the glenohumeral joint consist of a large spherical-like humeral head Applied Anatomy: Shoulder & Scapula – Part 1 – Bony Anatomy & Joint Movements by Triage | Feb 20, 2018 | Coaches Corner , Training You are unauthorized to view this page.

Both work together to produce normal movements. At these joints, the rounded head of one bone (the ball) fits into the concave articulation (the socket) of the adjacent bone (see Figure 3f). Posterior injection of the shoulder joint The hip-joint, like the shoulder, is a ball-and-socket joint, and, like it, moves in all directions.The main function of the shoulder is mobility, but the functions of the hip are mobility and support. The shoulder mechanism provides the upper limb with a range of motion exceeding that of any other joint mechanism. J. Functional anatomy of knee: a.
