Scapula

Anatomy & Physiology Anatomy is the study of the structure and relationship between body parts. Physiology is the study of the function of body parts and the body as a whole. Aims and Objectives  The composition of bone  The structure of a long bone  Classifying the types of joint found in the body  Description of synovial joint  How joint operates  How two different systems communicate for normal functioning of a joint  Description of a disease involving the musculoskeletal system …

role in the motion of the rotator cuff. The four muscles that are responsible for this motion are: the Supraspinatus muscle, the Infraspinatus muscle, the Teres Minor muscle, and the Subscapularis muscle. Each of these muscles originate from the scapula and attach into the humerus. The Supraspinatus muscle originates in the Supraspinatus Fossa and attaches to the greater tubercle of the humerus. The infraspinatus originates in the Infraspinatus Fossa and like the Supraspinatus muscle, attaches…

Scapula: The scapula attaches the upper arm to the thorax. This stabilizes the arm and allows the shoulder to move around with ease. Humerus: The humerus connects the shoulder with the elbow, it allows the lower part of the arm to move in a wide range of directions…

oriented, 72 year old, widowed female. She is a retired housekeeper residing in Michie, Tennessee. She presents to the clinic today with complaints of an itchy rash under her right axilla that is accompanied by severe pain that radiates toward her right scapula. She states her right ear is also aching. Source and Reliability Self-referred. Deemed reliable. Says she came to clinic due to severe discomfort. Chief Complaint “This rash started on Wednesday, and has gotten much worse. It is oozing…

subclavius (originates on the ribs and inserts on the clavicle), and pectoralis minor (attaches to the scapula). Muscles that move the arm consist of: deltoid (the major abductor), supraspinatus (assists the deltoid), subscapularis/teres major (produce medial rotation at the shoulder), infraspinatus/teres minor (produce lateral rotation at the shoulder), coracobrachialis (attaches to the scapula producing flexion and adduction at…

Briefly identify and discuss bones of the appendicular and axial skeletons. • The axial skeleton consists of the following bones. The skull is made of: • There are 2 parietal bones that form the superior and lateral parts of the skull. • There are 2 temporal bones that form the inferolateral parts of the skull. • The frontal bone forms what we know as the forehead (Cancer 2016). • The occipital bone is posterior making up most of the base of the skull. • The ethmoid bone forms the anterior…

The glenohumeral joint is one of the four joints that comprise the shoulder complex. The joint is considered to be the most mobile and least stable joint. The articular surfaces of the glenohumeral joint are the head of humerus and glenoid fossa of scapula. The humeral head can be in articulation with the glenoid fossa in any position of joint because the head of the humerus is larger than the glenoid fossa. This relationship is best compared with a golf ball siting on a tee, with stability…

The Glenoid Labrum: Labral Tear Number Twenty-Two PED161 2 LABRAL TEAR The Glenoid Labrum is a protective disk of fibrocartilage that surrounds and deepens the cavity of the Glenoid. The labrum allows for full range of motion, stability, and cushioning in the shoulder. It is attached to the edge of the shoulder socket and supports the ball of the joint -or the head of the arm bone, known as the humerus- in order to stay in place. When the fibrocartilage of the labrum is torn, it is…

primarily involved are the elbow and shoulder. The elbow is a hinge joint formed by the humerus and ulna. The shoulder is a ball and socket joint formed between the humerus and the scapula. The joints that are involved in a throw are the shoulder and the elbow. The bones in the shoulder are the humerus and the scapula. The bones that are used in the elbow are the humerus and the ulna. In the shoulder the action is horizontal hyperextension and in the elbow it is extension. The muscles that are…

The bicep brachii consists of two heads; the long head and short head. The long head originates at the supraglenoid tubercle above the socket of the scapula. The origin of the short head is at the carocoid process of the scapula. Both heads unite to form one large muscle at the interior side of the humerus and attach to the radial tuberosity (the insertion). Difference and similarities between the different types of muscle and the different…
