The medial two-thirds of the fossa have 3 longitudinal oblique ridges, and another thick ridge adjoins the lateral border; they run outward and upward. The clavicle was present in saurischian dinosaurs but largely absent in ornithischian dinosaurs. In such instances, due to the likelihood of simultaneous cognitive impairment, a treatment method called neuromuscular re-education is a large component of physical and occupational therapy treatments. Two important arteries, the axillary artery and the subclavian artery, run anterior to the scapula an… This type of treatment guides an individual to complete basic strengthening activities (and eventually functional activities such as dressing, toileting, bathing, and more) using outlined methods in order to assist with reshaping the brain and building motor programs. [13] A simple clinical and etiologic classification of the winged scapula is proposed based on the study of these patients in conjunction with a review of the literature. [21] The name scapula might be related that due to existence of the spine of the scapula a concavity exist in the scapula. The ridges give attachment to the tendinous insertions, and the surfaces between them to the fleshy fibers, of the subscapularis muscle. The first supposes that shoulder can be literally translated as that which shields or protects,[30] as its possibly related to Icelandic skioldr, shield and skyla, to cover, to defend. Animation. At the upper part of the fossa is a transverse depression, where the bone appears to be bent on itself along a line at right angles to and passing through the center of the glenoid cavity, forming a considerable angle, called the subscapular angle; this gives greater strength to the body of the bone by its arched form, while the summit of the arch serves to support the spine and acromion. The inferior angle is formed by the union of the medial and lateral borders of the scapula. In anatomy, the scapula (plural scapulae or scapulas[1]), also known as the shoulder bone, shoulder blade, wing bone or blade bone, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Many muscles are located in the area of the shoulder girdle, including rotator cuff muscles, nerve networks such as the brachial plexus, and upper arm muscles. The scapula provides attachment to several groups of muscles. The lateral angle is the thickest part of the bone, and is sometimes called the head of the scapula. Match. Spell. Costal surface of left scapula. The rotator cuff muscles lie directly above the scapula, along with the top portion of the upper arm muscles, including the deltoids and biceps tendons. The resulting three-boned structure is still seen in modern monotremes, but in all other living mammals, the procoracoid has disappeared, and the coracoid bone has fused with the scapula, to become the coracoid process. the body of scapula is thin , flat and triangular with two surfaces- ventral and dorsal. Lin JJ, Hanten WP, Olson SL, et al. "Scapula (Shoulder Blade) Anatomy, Muscles, Location, Function | EHealthStar", "II. As mentioned, this is often a crucial impairment in those affected by neurological events such as a stroke due to a blockage of nerve and blood supply to this area. Additionally, due to the location of the scapula on the axilla, there are many lymph nodes and lymph networks in this area which assist with fluid drainage and balance within the body. Winging of the scapula is either static or dynamic. The flat bones include the scapula (wingbone), the ribs, and the sternum (breastbone). Thank you, {{form.email}}, for signing up. Dorsal surface. The other more common type of fracture is through the surgical neck of the scapula. Ph… being a flat, broad blade, with the latter three words etymological related to each other. For example, in frogs, the procoracoid bones may be braced together at the animal's underside to absorb the shock of landing, while in turtles, the combined structure forms a Y-shape in order to allow the scapula to retain a connection to the clavicle (which is part of the shell).
