Attachments

Muscles and ligaments that attach to the clavicle include:

Attachment on clavicle	Muscle/Ligament	Other attachment
Superior surface and anterior border	Deltoid muscle	deltoid tubercle, anteriorly on the lateral third
Superior surface	Trapezius muscle	posteriorly on the lateral third
Inferior surface	Subclavius muscle	subclavian groove
Inferior surface	Conoid ligament (the medial part of the coracoclavicular ligament)	conoid tubercle
Inferior surface	Trapezoid ligament (the lateral part of the coracoclavicular ligament)	trapezoid line
Anterior border	Pectoralis major muscle	medial third (rounded border)
Posterior border	Sternocleidomastoid muscle (clavicular head)	superiorly, on the medial third
Posterior border	Sternohyoid muscle	inferiorly, on the medial third
Posterior border	Trapezius muscle	lateral third

SOME IMP POINTS:-

1-TUBERCLE:In anatomy, the term tubercle may describe a round nodule, small eminence, or warty outgrowth found on bones or skin, or, in cases of tuberculosis, in the lungs.

2-GROVE:groove, or narrow depression or channel in a surface.

3-facet

A small smooth area on a bone or other firm structure.

4-Ligament: In anatomy, a ligament is the fibrous tissue that connects bones to other bones.

5-Bony Land Marks:-The 'bony landmarks' of the human body are distinguishing features found on the bones of the skeletal system. Each bone of the human body has at least one or two "landmarks" that serve to distinguish that bone from other bones. A bony landmark could be anything from a line or a notch in its surface to a large bump or projection. These landmarks are often named for what they are and where they are( a notch in the bone at the top of the scapula = suprascapular notch), but the names of the landmarks vary widely. Clinically, these bony features are important in palpation, the physical examination of the tissues of the body, often done with the hands/fingers, because they serve as the somewhat fixed landmarks of the body. Hence, bony landmarks.

6- Muscle origin and insertion are terms that describe where the muscle attaches to the bones / connective tissues. They are relative. Generally, the origin is where the muscles "originates" on the body (usually a bone, but not always) of the stationary part. The insertion is where the muscle attaches on the bone of the moving lever across a single, or multiple, joint lines. When the muscle contracts, it pulls the insertion to the origin.

MUSCLES:-

1-The sternohyoid muscle is a thin, narrow muscle attaching the hyoid bone(It is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. ) to the sternum

For hyoid bone(upper one)

2-Sternocleidomastoid muscle:- In human anatomy, the sternocleidomastoid muscle (pron.: /ˌstɜrnɵˌkliːdɵˈmæstɔɪd/), also known as sternomastoid and commonly abbreviated as SCM, is a paired muscle in the superficial layers of the anterior portion of the neck. When acting together it flexes the neck and extends the head. When acting alone it rotates to the opposite side (contralaterally) and slightly (laterally) flexes to the same side.

3-Trapezious Muscle:- In human anatomy, the trapezius is a large superficial muscle that extends longitudinally from the occipital bone to the lower thoracic vertebrae and laterally to the spine of the scapula (shoulder blade). Its functions are to move the scapulae and support the arm.

4-The pectoralis major ( Latin: pector = breast) is a thick, fan-shaped muscle, situated at the chest (anterior) of the human body. It makes up the bulk of the chest muscles in the male and lies under the breast in the female. Underneath the pectoralis major is the pectoralis minor, a thin, triangular muscle

 

5-Deltoid Muscle:- In human anatomy, the deltoid muscle is the muscle forming the rounded contour of the shoulder. Anatomically, it appears to be made up of three distinct sets of fibers though electromyography(is a technique for evaluating and recording the electrical activity produced by skeletal muscles) suggests that it consists of at least seven groups that can be independently coordinated by the central nervous system.^[1]
