How many muscles are in your clavicle?

There are five muscles that make their origin or insertion on the clavicle: pectoralis major and sternocleidomastoid muscles medially; subclavius muscle centrally; and deltoid and trapezius muscles distally (Gray, 1918; Netter, 1987).

Where is the clavicular?

The clavicle is the bone that connects the breastplate (sternum) to the shoulder. It is a very solid bone that has a slight S-shape and can be easily seen in many people. It connects to the sternum at a joint with cartilage called the sternoclavicular joint.

What does clavicular mean?

: a bone of the shoulder girdle typically serving to link the scapula and sternum.

What are clavicle muscles?

The clavicle is an S-shaped bone that is anchored by strong ligamentous attachments on both its medial and lateral ends. Muscular attachments to the clavicle include the sternocleidomastoid, pectoralis major, and subclavius muscles proximally and the deltoid and trapezius muscles distally.

What muscle is the scapula?

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. The intrinsic muscles of the scapula include the rotator cuff muscles, teres major, subscapularis, teres minor, and infraspinatus.

What is the muscle above your collarbone called?

The largest of these shoulder muscles is the deltoid. This large triangular muscle covers the glenohumeral joint and gives the shoulder its rounded-off shape. It stretches across the top of the shoulder from the clavicle in the front to the scapula in the back.

What are armpit muscles called?

Pectoralis major: This large fan-shaped muscle stretches from the armpit up to the collarbone and down across the lower chest region. It connects to the sternum (breastbone). Pectoralis minor: The smaller of the pectoralis muscles, this muscle fans out from the upper ribs up to the shoulder area.

What is the Subclavius muscle?

The subclavius muscle is a small triangular muscle of the pectoral region which depresses the shoulder.

Which joint is in shoulder?

glenohumeral joint
The glenohumeral joint is what most people think of as the shoulder joint. It’s the major joint in the shoulder, where the rounded top, or head, of the humerus, nestles into a rounded socket of the scapula, called the glenoid. This ball-and-socket construction allows for circular movement of the arm.

What muscles are under the clavicle?

The subclavius muscle is a small muscle that lies deep to pectoralis major muscle. It passes from rib I at the junction between the rib and its costal cartilage to a groove on the inferior (lower) surface of the clavicle.

What causes neck and clavicle pain?

Clavicle pain is often caused by sports injuries and less commonly by joint degeneration, infection, or tumors. Learn how to cope it here. The collarbone (clavicle) is the curved bone you feel between your neck and shoulder.

What does muscle have it insertion at the clavicle?

Four muscles are attached to the medial third of the clavicle: The sternocleidomastoid muscle, where the muscular clavicular head of the muscle is attached to the superior surface of the bone. The pectoralis major muscle, which is attached to the anterior surface of the bone. The subclavius muscle, which is attached to a groove found in the middle of the bone’s inferior surface.
