2021年9月6日 · The scapula, alternatively known as the shoulder blade, is a thin, flat, roughly triangular-shaped bone placed on either side of the upper back. This bone, along with the clavicle and the manubrium of the sternum, composes the pectoral (shoulder) girdle, connecting the upper limb of the appendicular skeleton to the axial skeleton .

2023年12月12日 · The scapula, also called the shoulder blade, is a thin, flat, roughly triangular bone situated on each side of the upper back. Together with the clavicle and the manubrium of the sternum, it forms the pectoral (shoulder) girdle, linking the upper limb of the appendicular skeleton to the axial skeleton.

The scapula upwardly rotates in the frontal plane, posteriorly tilts in the parasagittal plane, and externally rotates in the transverse plane during functional elevation. Scapular control is essential to scapulohumeral coordination. Posterior tilting is responsible for humeral clearance during the acromiohumeral portion of shoulder elevation.

2024年4月12日 · Orthogonal to the AP shoulder (note: as is an axillary view); this view is a pertinent projection to assess suspected dislocations, scapula fractures, and degenerative changes. It is also useful in seeing both the coracoid and acromion process in profile.

2025年1月21日 · The scapula is located on the posterior side of the ribcage, between the second and seventh ribs. It lies on the upper back part of the body, symmetrically on each side, and is positioned over the dorsal surface of the rib cage .

2024年9月18日 · Scapula has three angles, lateral, superior and inferior. The superior and inferior angles of the scapula are unremarkable. The lateral angle features a region called the glenoid process of scapula. The glenoid process is connected to the lateral angle via a constriction called the neck of scapula.

2014年12月2日 · What is the shoulder blade (scapula)? The shoulder blades are two flat, symmetrical bones on each side of the top of your back [1]. The medical term for the shoulder blade is the scapula. Scapula Function. The shoulder blades attach the upper arm and upper back muscles that raise your arms and shoulders and bend your neck backwards or sideways.

2023年10月30日 · Prepare yourself for our scapula diagram activities and scapula quizzes! First, let’s take a basic overview. Anatomy of the scapula is often taught alongside the humerus, since they are the two primary bones of the shoulder joint. Next, it’s time to test your memory with a humerus and scapula labeling quiz.

The side of the scapula can be figured out by holding the scapula in such a way that: The glenoid cavity faces laterally, forwards, and a bit upwards (at an angle of 45 ° from the coronal plane). The coracoid process is directed forwards.

On the lateral side, the spine of the scapula extends in the form of a large process — the acromion (acromion). It has a clavicular facet (facies articularis clavicularis) that connects to the acromial end of the clavicle. The base of the lateral angle of the scapula is slightly narrowed and is called the neck of the scapula (collum scapulae).
