Information about Trapezoid Ligament

Ligament: Trapezoid ligament
The left shoulder and acromioclavicular joints, and the proper ligaments of the scapula. (Trapezoid visible at center top.)

The trapezoid ligament, 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.

In anatomy, the term ligament is used to denote three different types of structures:[1]
  1. Fibrous tissue that connects bones to other bones. They are sometimes called "articular ligaments"[2], "fibrous ligaments", or "true ligaments".

In human anatomy, the upper limb (also upper extremity) refers to what in common English is known as the arm, that is, the region of the shoulder to the fingertips. It includes the entire limb, and thus, is not synonymous with the term upper arm.

In human anatomy, the shoulder comprises the part of the body where the arm attaches to the torso. It is made up of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) as well as associated muscles, ligaments and tendons.
