Also called the shoulder blade, it is a flat triangular bone, a pair of which form the back part of the shoulder girdle.
The articulation between the head of the HUMERUS and the glenoid cavity of the SCAPULA.
The twelve spinal nerves on each side of the thorax. They include eleven INTERCOSTAL NERVES and one subcostal nerve. Both sensory and motor, they supply the muscles and skin of the thoracic and abdominal walls.
Part of the body in humans and primates where the arms connect to the trunk. The shoulder has five joints; ACROMIOCLAVICULAR joint, CORACOCLAVICULAR joint, GLENOHUMERAL joint, scapulathoracic joint, and STERNOCLAVICULAR joint.
A depression in the lateral angle of the scapula that articulates with the head of the HUMERUS.
A cartilage-capped benign tumor that often appears as a stalk on the surface of bone. It is probably a developmental malformation rather than a true neoplasm and is usually found in the metaphysis of the distal femur, proximal tibia, or proximal humerus. Osteochondroma is the most common of benign bone tumors.
Bone in humans and primates extending from the SHOULDER JOINT to the ELBOW JOINT.
Compression of the rotator cuff tendons and subacromial bursa between the humeral head and structures that make up the coracoacromial arch and the humeral tuberosities. This condition is associated with subacromial bursitis and rotator cuff (largely supraspinatus) and bicipital tendon inflammation, with or without degenerative changes in the tendon. Pain that is most severe when the arm is abducted in an arc between 40 and 120 degrees, sometimes associated with tears in the rotator cuff, is the chief symptom. (From Jablonski's Dictionary of Syndromes and Eponymic Diseases, 2d ed)
A set of twelve curved bones which connect to the vertebral column posteriorly, and terminate anteriorly as costal cartilage. Together, they form a protective cage around the internal thoracic organs.
The morphologic and physiological changes of the MUSCLES, bones (BONE AND BONES), and CARTILAGE of the body, i.e., MUSCULOSKELETAL SYSTEM, during the prenatal and postnatal stages of development.
A bone on the ventral side of the shoulder girdle, which in humans is commonly called the collar bone.
Partial or total replacement of a joint.
An order of the class MAMMALS that consists of one family, TUPAIIDAE (tree shrews), 5 genera (one of which is TUPAIA), and 16 species. Their recent distribution is from India to the Philippines, southern China to Java, Borneo, Sumatra, Bali, and other islands in those regions.
The musculotendinous sheath formed by the supraspinatus, infraspinatus, subscapularis, and teres minor muscles. These help stabilize the head of the HUMERUS in the glenoid fossa and allow for rotation of the SHOULDER JOINT about its longitudinal axis.
Injuries to the fibrous cords of connective tissue which attach muscles to bones or other structures.
The lateral extension of the spine of the SCAPULA and the highest point of the SHOULDER.
Forcible or traumatic tear or break of an organ or other soft part of the body.
