It does not properly belong to this articulation, but is usually described with it, since it forms a most efficient means of retaining the clavicle in contact with the acromion. It consists of two fasciculi, called the trapezoid and conoid ligaments. The acromion process, or simply the acromion, is an anatomical feature on the scapula. ...


Trapezoid Ligament

The Trapezoid Ligament (ligamentum trapezoideum), the anterior and lateral fasciculus, is broad, thin, and quadrilateral: it is placed obliquely between the coracoid process and the clavicle.


It is attached, below, to the upper surface of the coracoid process; above, to the oblique ridge on the under surface of the clavicle.


Its anterior border is free; its posterior border is joined with the conoid ligament, the two forming, by their junction, an angle projecting backward.


Conoid Ligament

The Conoid Ligament (ligamentum conoideum), the posterior and medial fasciculus, is a dense band of fibers, conical in form, with its base directed upward.


It is attached by its apex to a rough impression at the base of the coracoid process, medial to the trapezoid ligament; above, by its expanded base, to the coracoid tuberosity on the under surface of the clavicle, and to a line proceeding medialward from it for 1.25 cm.


These ligaments are in relation, in front, with the Subclavius and Deltoideus; behind, with the Trapezius. The deltoid muscle is the muscle forming the rounded contour of the human shoulder. ... Trapezius In human anatomy, the trapezius is a large superficial muscle on a persons back. ...
