It is classed as a long bone and can be palpated along its length.In thin individuals, it is visible under the skin. Inferiorly the conoid and trapezoid components of the CC ligament provide stability between the clavicle and the coracoid process of the scapula. Radial tuberosity, Styloid process: What is the proximal (origin) attachment of Pectoralis major (sternal head) Sternum, Costal Cartilages 1-6: What are the proximal attachments of Latissimus dorsi (coughing muscle)? Insertion: (distal attachments) a. muscles 5 Here we will discuss the different functions, the anatomical landmarks, and the muscle attachments of this long bone. Clavicle bone has a lot of muscle attachments which insert on the upper and under the surface of the bone. Name the muscles & ligaments attached and structures related to the medial 2/3rd of clavicle. The clavicle also acts as a bony framework for muscle origin and insertion. Lateral third is flat so has two borders and two surfaces - anterior border: deltoid muscle - posterior border: trapezius muscle - superior surface: no attachment - subcutaneous - inferior surface: no muscle attachment - has conoid tubercle and trapezoid line Medial two-thirds has four surfaces - … It acts as a strut to keep the scapula in place so the arm can hang freely. T6-S5 vertebrae, Illiac crest, Ribs 9-12: Name the 3 functions of the deltoid The Sternoclavicular Joint (SC joint) is formed from the articulation of the medial aspect of the clavicle and the manubrium of the sternum. The SC joint is the only true articulation connecting the upper limb to the axial skeleton, and that it’s the least constricted joint in the human body[1]. Muscle attachments. Intermediate Back Muscles […] a. Superficial Back Muscles b. Occasionally, the clavicle is pierced by a branch of the supraclavicular nerve. The clavicle connects the sternum (breastbone) to the scapula via the acromion. Clavicular head: Anterior surface of medial half of clavicle; Sternal head: Anterior surface of manubrium and sternum up to sixth costal cartilages b. Sternal head: sternum, upper costal cartilages (1-6), and the aponeurosis of the external oblique. 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: Muscle Attachments. The relative paucity of soft tissue attachments in the middle third may have an influence on the incidence of fractures in this region and certainly influences the deformity after fracture. Articulations. The clavicle is thicker and more curved in manual workers, and the sites of muscular attachments are more marked. Two muscles are attached to the lateral third of the clavicle: The trapezius muscle, which is attached along the posterior surface of the lateral third of the clavicle. A total of five muscles are attached to the clavicle, found distributed at either the lateral third or medial two thirds of the bone. Attachments. Along with the pectoralis major and pectoralis minor muscles, the subclavius muscle makes up the anterior axioappendicular muscles, also known as anterior wall of the axilla. It runs superomedially underneath the sternocleidomastoid muscle. Sorry your browser does not support HTML 5 canvas elements. A type IIB fracture of the distal clavicle. The clavicle has three main functions: Attaches the upper limb to the trunk as part of the ‘shoulder girdle’. The subclavius muscle is a relatively minor muscle located deep within the chest. This large triangular muscle covers the glenohumeral joint and gives the shoulder its rounded-off shape. The upper third of the trapezius inserts on the superior surface of the outer third of the clavicle, opposite the site of origin of the clavicular head of the deltoid along its anterior edge. Intermediate Back Muscles and c. Deep Back Muscles Superficial Back Muscles Action Movements of the shoulder. The sternocleidomastoid muscle is a two-headed neck muscle, which true to its name bears attachments to the manubrium of sternum (sterno-), the clavicle (-cleido-), and the mastoid process of the temporal bone (-mastoid).. Pectoralis Major Muscle: The pectoralis major is a thick, fan-shaped muscle, located at the chest. It is one of four joints that compose the Shoulder Complex.  … The subclavius is a small triangular muscle, placed between the clavicle and the first rib.
