What bone links your sternum to your scapula?

What bone links your sternum to your scapula?

The clavicle bone or collarbone is an S-shaped bone that connects the scapula to the sternum or breastbone. It forms two joints: the acromioclavicular joint, where it articulates with the acromion process of the scapula, and the sternoclavicular joint where it articulates with the sternum or breast bone.

What is the scapula to the sternum?

Clavicle. The clavicle, commonly called the collarbone, is an S-shaped bone that acts like a mechanical rod that links the scapula to the sternum (Fig. 4.3). The flattened lateral portion—called the acromial end—articulates with the acromion of the scapula, forming the acromioclavicular (AC) joint.

Is the sternum lateral to the scapula?

At its medial end this large joint surface articulates with the sternum. At the lateral end this smaller surface articulates with the scapula. On the underside, massive ligaments are attached, here laterally, and here medially. The scapula is a much more complicated bone.

What bone links the scapula and the sternum above the first rib?

clavicle
The clavicle is a palpable, subcutaneous long bone that links the shoulder girdle to the trunk (Moore, 1992; Bhandari and Adili, 2011). It is located above the first rib, and it articulates with the sternal manubrium proximally (sternoclavicular joint) and the acromion distally (acromioclavicular joint) (Gray, 1918).

Why does the area around my sternum hurt?

Costochondritis is the most common cause The most common cause of sternum pain is a condition called costochondritis. This occurs when the cartilage that connects your ribs to your sternum becomes inflamed. Symptoms of costochondritis include: sharp pains or aches on the side of your sternum area.

Is the scapula a stationary bone?

For example, the scapula is a freely movable bone that serves as the origin for several muscles that move the arm. When the arm muscles contract, the scapula must be held steady. The three regions of the body—the free limbs, the trunk, and the head each have distinct patterns of muscle development.

Where is the serratus anterior muscle located in the scapula?

Serratus anterior muscle – its insertion is along the medial border, from the superior angle to the inferior angle. This muscle protracts and rotates the scapula. It is innervated by the long thoracic nerve. Pectoralis minor muscle – it inserts into the coracoid process. Its actions consist of protraction and depression of the scapula.

Where does the trapezius muscle insert on the scapula?

Inserting on the Scapula. Trapezius muscle – it inserts superiorly along the spine, acromion process, and clavicle. Its actions include elevation of the scapula and rotation of scapula during abduction of humerus beyond 90 degrees. It is innervated by the accessory nerve.

Is the sternal end of the clavicle a ligament?

The inferior surface of the sternal end is marked by a rough oval depression for the costoclavicular ligament (a ligament of the SC joint). The shaft of the clavicle acts a point of origin and attachment for several muscles – deltoid, trapezius, subclavius, pectoralis major, sternocleidomastoid and sternohyoid

Where does the deltoid muscle originate in the scapula?

Deltoid muscle – it originates inferiorly along the scapula spine to the acromion (and lateral third of the clavicle). Its actions include flexion and medial rotation (anterior fibres), abduction (middle fibres), extension and lateral rotation (posterior fibres) at the shoulder joint. It is innervated by the axillary nerve.
