Study Notes on the Interclavicular Ligament and Scapula Borders

Ligaments and Anatomical Structure of the Clavicle and Scapula

Interclavicular Ligament

• Definition: The interclavicular ligament connects the superior and medial ends of the clavicle.

• Function: It plays a role in stabilizing the sternoclavicular joint by linking the two clavicles, thereby helping to maintain proper posture and movement of the shoulders.

Medial Border of the Scapula

• The medial border of the scapula runs vertically along its inner side.

• It features two notable anatomical landmarks:

  • Superior Angle: The prominent point at the top of the scapula where the medial border meets the superior border.

  • Inferior Angle: The lower point where the medial border meets the lateral border.

Classification of Borders

1. Vertebral Border

   • Also known as the medial border, it is located between the superior angle and the inferior angle of the scapula.

   • This border lies closest to the vertebral column and provides attachment points for muscles such as the rhomboids and serratus anterior.

Labeling Considerations

• When labeling anatomical diagrams, ensure that both the interclavicular ligament and the borders of the scapula are clearly indicated for educational purposes. Clarification on these terms enhances understanding of shoulder stability and movement.
