What does the scapula do? Answer   Scapula is the scientific term for shoulder blade. It provides a foundation for the attachments of the muscles that move the arm. There are many functions of the … scapula. It forms part of the shoulder girdle and many (16) muscles are associated with it. The actions that the muscles have on it include: elevation (shrugging), depression (slumping), abduction, adduction, rotation, and tipping.

- Causes of Scapular Winging. The scapula, or shoulder blade, has a large number of muscles attaching it to the shoulder joint. These muscles work in tandem to move the arm and keep the shoulder blade firmly attached to the back.

- In anatomy, the scapula (plural scapulae or scapulas) a.k.a. shoulder blade or wing bone, is the bone that connects the humerus (upper arm bone) (also known as the brigham) with the clavicle (collar bone).

Levator scapulae muscle Levator scapulae muscle. Anatomy and supply. The levator scapulae is a long muscle of the shoulder girdle. It originates at the transverse processes of the atlas and axis as well as the posterior tubercles of the 3rd-4th cervical vertebrae. It inserts at the superior angle and medial border of the scapula.

Winged scapula Definition/Description. The term ‘winged scapula’ (also scapula alata) is used when the muscles of the scapula are too weak or paralyzed, resulting in a limited ability to stabilize the scapula. As a result, the medial border of the scapula protrudes, like wings. The main reasons for this condition are musculoskeletal-and neurological-related.

Acromion Acromion shoulder is the lateral extension of the spine of the scapula. Scapula is the scientific name for the shoulder blade. The spine leads to a ‘head’ and here it bears two processes – the acromion process and the carocoid process.cromion Scapula. Scapula is the scientific name for the shoulder blade. It is a kind of triangular, flat bone lying over the back of the upper ribs. The scapula serves as an attachment for the muscles of the arm, neck, chest and the back. The back of the scapula is divided into unequal portions by a spine.

Winging Scapula Winging of the scapula is a surprisingly common physical sign, but because it is often asymptomatic it receives little attention. However, symptoms of pain, weakness, or cosmetic deformity may demand attention. Winging is also a useful sign to suggest underlying problems with the shoulder. Winging may be caused by injury or dysfunction of the muscles themselves or the nerves that supply the muscles. Causes: 1  Loss of serratus anterior muscle function. 2  Loss of trapezius muscle function. 3  Weakness of all the scapula stabilisers. 4  Loss of the scapular suspensory mechanism.

Muscles That Move the Scapulae Next we’ll start breaking down the different body parts, beginning with the muscles that move the scapulae. The scapula, commonly referred to as the shoulder blade, is the bone that attaches to the back of your rib cage. It is the bone that creates the shoulder joint with the upper arm, called the humerus bone.The scapulae can move in six actions and each action has primary muscles that create that action.ext we’ll start breaking down the different body parts, beginning with the muscles that move the scapulae.

THE SHOULDER GIRDLE Upper Fibers: elevation of scapula, upward rotation, and extension and rotation of the head and neck. Middle Fibers: elevation, upward rotation, and adduction (retraction) of the scapula. Lower fibers: depression, adduction (retraction), and upward rotation of the scapula.

The Cervical Spine Movements of the scapula are brought about by the scapular muscles. 1  The scapula can perform six actions: 2  Elevation: upper trapezius and levator scapula. 3  Depression: lower trapezius. 4  Retraction (adduction): rhomboids and middle trapezius. 5  Protraction (abduction): serratus anterior. 6  Upward rotation: upper and middle trapezius.

Levator scapulae muscle As the name indicates, the main function of the levator scapulae is the elevation of the scapula. Thereby it simultaneously pulls the entire scapula medially. This movement is helpful when bringing the elevated arm back to the neutral position.

- The scapula is a wider flat bone at the back of the shoulder. The Scapula is also held in place by the end of the clavicle that is not connected to that thorax. The triceps muscle Starts on the scapula and runs down the back of the upper arm to the lower end of the humerous bone, which is the third bone in the shoulder.

Shoulder Structure, Function and Common Problems The shoulder is not a single joint, but a complex arrangement of bones, ligaments, muscles, and tendons that is better called the shoulder girdle. The primary function of the shoulder girdle is to give strength and range of motion to the arm. The shoulder girdle includes three bones—the scapula, clavicle and humerus.ursae occur in connective tissue wherever two body parts—other than joints—move against each other. Their function is to lessen the friction between tendon and bone, ligament and bone, tendons and ligaments, and between muscles. Inflammation or infection of the bursa is called bursitis.

- Scapula: The shoulder blade (or wingbone), the familiar flat triangular bone at the back of the shoulder. The word scapula (with the accent on the first syllable) is Latin. The Romans always employed the plural scapulae, the shoulder blades. The term subscapular means under (sub) the scapula. The subscapularis muscle originates beneath the scapula. This muscle moves the arm by turning it inward (internal rotation). The subscapularis muscle tendon is part of the rotator cuff.

Levator scapulae Its primary function is to lift the scapula, which is the triangle-shaped bone located at the back of the shoulder that connects the upper arm bone (humerus) with the clavicle (collarbone). If a person experiences a stiff shoulder or neck, the levator scapulae muscle is often involved.he upper part of the levator scapulae muscle is covered by the sternomastoid muscle, the muscle that rotates and flexes the head.

Acromion In this highly specialized endoskeletal structure, the scapula is a dorsal (directed upwards) process attached to the first rib; the coracoid is a posteroventral (directed backward and down) process; and the acromion is a medioventral (directed inwards and down) process (also known as the prescapular process) located at the base of the scapula.
