is clavicle part of shoulder?

The shoulder joint is formed where the humerus (upper arm bone) fits into the scapula (shoulder blade), like a ball and socket. Other important bones in the shoulder include: The acromion is a bony projection off the scapula. The clavicle (collarbone) meets the acromion in the acromioclavicular joint.

The rotator cuff covers the head of the upper arm bone and attaches it to the shoulder blade. The AC (acromioclavicular) joint is formed where a portion of the scapula (acromion) and the clavicle meet and are held together by tough tissues (ligaments) that act like tethers to keep the bones in place.

The clavicular (anterior) fibers of deltoid act along with pectoralis major to produce flexion of the arm during walking or running motions. These fibers are also active during internal (medial) rotation of the humerus.

AC Arthritis (Acromioclavicular Arthritis) Arthritis is a type of damage to a joint that can cause inflammation. AC arthritis affects the acromioclavicular (AC) joint. This joins the shoulder blade (scapula) and the collarbone (clavicle). The joint has ligaments and cartilage.

In humans, the rib cage, also known as the thoracic cage, is a bony and cartilaginous structure which surrounds the thoracic cavity and supports the shoulder girdle to form the core part of the human skeleton.

Acromioclavicular (AC) joint arthrosis or osteoarthritis of the acromioclavicular joint is a condition that develops when the cartilage cushioning the AC joint in the shoulder begins to wear out. The shoulder is a 'ball-and-socket' joint.

The appendicular skeleton is made up of bones of the upper and lower extremities and the boney girdles, which hold the extremities to the axial skeleton. It consists of the pectoral girdle, which is the scapula and clavicle. The upper extremities are the humorous, ulna, radius, carpals, metacarpals, and phalanges.

supraclavicular lymph nodes. The supraclavicular lymph nodes are a set of lymph nodes found just above the clavicle or collarbone, toward the hollow of the neck.

Function. When the arm is the anatomical position, the pectoralis major acts as a strong adductor and internal rotator of the humerus at the shoulder joint. Acting independently, the clavicular portion of the muscle flexes the humerus up to 90 degrees in a horizontal plane.

Your acromioclavicular joint (ACJ) is the area where your collarbone meets your shoulder blade. Your acromioclavicular joint (ACJ) is the area where your collarbone meets your shoulder blade. Injuries to this area are most commonly caused by direct impact or through a fall.

In the upper back region, the trapezius, rhomboid major, and levator scapulae muscles anchor the scapula and clavicle to the spines of several vertebrae and the occipital bone of the skull.

Clavicle Fractures. The clavicle (collarbone) is one of the most fractured bones in the body. Symptoms of a broken collarbone include severe pain and swelling at the site of the fracture and with visible deformity in some cases.

Joint dislocations are classified as either "anterior" or "posterior," depending on the direction in which the collarbone is pushed during the injury: Anterior—the end of the clavicle is pushed forward, in front of the sternum (breastbone)

1.2. Indications for No Operative Treatment. The primary goal of treatment is to restore shoulder function to a normal level by setting preconditions which allow the clavicle to heal with minimal deformity, no loss of shoulder motion and minimized pain [10].

The appendicular skeleton includes the bones of the shoulder girdle, the upper limbs, the pelvic girdle, and the lower limbs.

Your collarbone (or clavicle) is the bone that runs horizontally between the top of your breastbone (sternum ) and shoulder blade (scapula). You can feel your collarbone by touching the area between your neck and your shoulder. A broken collarbone, also called a clavicle fracture, is when this bone breaks.

Introduction. The clavicle is a sigmoid-shaped long bone with a convex surface along its medial end when observed from cephalad position. It serves as a connection between the axial and appendicular skeleton in conjunction with the scapula, and each of these structures forms the pectoral girdle.
