Study Notes

Clavicle Anatomy

The clavicle is classified as a long bone.
The medial end of the clavicle is known as the sternal extremity.
The lateral end of the clavicle is referred to as the acromial extremity.
The lateral end articulates with part of the scapula, while the medial end articulates with the manubrium.
Positioned just above the first rib, the clavicle is a key component of the shoulder girdle.
Both the sternoclavicular (SC) and acromioclavicular (AC) joints are classified as synovial joints and exhibit gliding joint characteristics.
Adult males tend to have more sharply curved clavicles.

Scapula Anatomy

The scapula is a flat bone with two surfaces, three borders, and three angles.
The anterior surface of the scapula is also called the costal surface.
The posterior surface features two fossae: the supraspinous fossa and infraspinous fossa, separated by the scapular spine.
The lateral end of the scapular spine is known as the acromion.
The scapular notch is located near the lateral end of the superior border of the scapula.
The coracoid process serves as the most anterior bony projection of the scapula.
Scapular borders include superior, lateral, and medial, while the angles consist of superior, inferior, and lateral.

Shoulder Girdle Components

The anterior section of the shoulder girdle is formed by the clavicle.
The subscapularis muscle covers the costal surface of the scapula and attaches to it.
The anatomical neck of the humerus is situated between the head and the tubercles.

Joint and Bursa Information

Bursa are small synovial fluid-filled sacs that alleviate pressure and minimize friction within tissues.
Articulations of the shoulder girdle include:
- Acromioclavicular (AC) joint
- Sternoclavicular (SC) joint
- Scapulohumeral joint
The humerus articulates with the glenoid cavity of the scapula, while the medial end of the clavicle articulates with the sternum.
The acromion of the scapula connects with the lateral end of the clavicle.
