Scapula Bone – Introduction

The scapula is a flat, triangular-shaped bone that lies adjacent to the posterior surface of ribs. Seventeen muscles attach to the scapula, and it articulates with the clavicle to form the shoulder girdle or pectoral girdle, which supports movements of the humerus.

Scapula Bone – Anterior Anatomy

The bone markings of the anterior scapula include the superior border, medial border, lateral border, superior angle, lateral angle, inferior angle, coracoid process, suprascapular notch, glenoid cavity, infraglenoid tubercle, and the suprascapular fossa.

Scapula Bone – Posterior Anatomy

The bone markings of the posterior scapula include the superior border, medial border, lateral border, superior angle, lateral angle, inferior angle, scapular spine, acromion, supraspinous fossa, infraspinous fossa, glenoid cavity and the infraglenoid tubercle.

Clavicle Bone – An Introduction

The clavicle or collarbone is located superior to the first rib and runs horizontally from the manubrium of the sternum to the acromion of the scapula.

General Anatomy of the Hand and Wrist Bones

Twenty-seven bones form the hand and eight small carpal bones support the wrist.

Hand and Wrist Bones – Anterior (Palmar) View

The proximal row of bones in the hand include the scaphoid, lunate, triquetral, and pisiform bone. The distal row of bones in the hand include the trapezium, trapezoid, capitate, hamate bone. The metacarpals support the palm. The phalanges include fourteen bones that support the fingers.
