Description[edit | edit source]
The Deltoid muscle is a large triangular shaped muscle which lies over the glenohumeral joint and which gives the shoulder its rounded contour. It is named after the Greek letter delta, which is shaped like an equilateral triangle. It comprises 3 distinct portions each of which produces a different movement of the glenohumeral joint, commonly named the anterior, mid (or lateral) and posterior heads.
Origin[edit | edit source]
Anterior fibres/head[edit | edit source]
Lateral third, anterior surface of the clavicle (close to the lateral fibres of pectoralis major).
Mid/lateral head[edit | edit source]
Acromion process, superior surface.
Posterior head[edit | edit source]
Spine of the scapula, posterior border.
Insertion[edit | edit source]
Fibres from all heads converge to insert into the deltoid tuberosity on the humerus.
The deltoid fascia is continuous with the brachial fascia and connects to the medial and lateral intermuscular septa.
