What is scapula shape?

What is scapula shape?

The scapula is a flat, triangular-shaped bone (colloquially as the “shoulder blade”). It is located in the upper thoracic region on the dorsal surface of the rib cage. It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint.

What is the scapular in anatomy?

The scapula or shoulder blade is the bone that connects the clavicle to the humerus. The scapula forms the posterior of the shoulder girdle. It is a sturdy, flat, triangular bone. The scapula provides attachment to several groups of muscles.

What is a scapular position?

The scapular (shoulder blade) provides the “socket” and the “ball” is the head of your humerus (upper arm bone). The position that your shoulder blade sits in impacts the position of your shoulder joint. Without the contribution of the shoulder blade, you would be limited to approximately 120° of shoulder movement.

What is the scapular region?

The scapular region is on the superior posterior surface of the trunk and is defined by the muscles that attach to the scapula (shoulder blade). These muscles can be divided into: As it continues laterally, this spine forms the acromion (the bony high point of the shoulder).

Is scapula a bone or muscle?

The scapula, or shoulder blade, is a large triangular-shaped bone that lies in the upper back. The bone is surrounded and supported by a complex system of muscles that work together to help you move your arm.

What does the scapula look like?

The scapula forms the back of the shoulder girdle. In humans, it is a flat bone, roughly triangular in shape, placed on a posterolateral aspect of the thoracic cage.

What does the scapula do during shoulder flexion?

When we perform flexion, the glenohumeral (GH) joint contributes 100°-120°. The scapula on the thorax contributes to elevation (flexion and abduction) of the humerus by upwardly rotating the glenoid fossa 50° to 60° from its resting position.

What holds the shoulder blade in place?

There are ligaments that connect the shoulder blade (scapula) to the Humerus which include: coracohumeral ligament and the glenohumeral ligaments (superior, middle and inferior). helping absorb forces transmitted into the acromion by large muscles like the deltoid and trapezius.

Is the shoulder blade anterior or posterior?

Anterior or ventral – front (example, the kneecap is located on the anterior side of the leg). Posterior or dorsal – back (example, the shoulder blades are located on the posterior side of the body). Medial – toward the midline of the body (example, the middle toe is located at the medial side of the foot).

What muscles are under the scapula?

The rhomboid muscles are a large group of muscles in your upper back. They’re made up of the rhomboid major and the rhomboid minor. These and other muscles form the shoulder girdle that holds your shoulder blade and shoulder stable.

Can anyone wear a scapular?

Also, anyone may wear the brown scapular if it is blessed by a priest or deacon. Whether or not formally committed to the order, those who wear the scapular are considered part of the Carmelite order. It is unthinkable that any member of the people of God would wear the scapular in a mindless or careless manner.

Why is scapular retraction important?

Being able to retract your scapula is important because protracted scapulae make it difficult to move your shoulder joints well. Being able to pull your scapulae into proper position makes it possible to breathe and move freely without the weight of you arms dragging you (literally) down.
