Upper Limb Bones
Lessons on the clavicle, scapula, humerus, radius, ulna, carpal, and hand bones. Struggling? Learn how to study anatomy.

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
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.

Clavicle Bone Anatomy
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.

Humerus Bone Anatomy
The humerus is a long bone that supports the upper arm and it extends from the shoulder joint to the elbow joint.

Humerus Bone – Anterior Markings

Humerus Bone – Posterior Markings
The posterior markings of the humerus bone.

Radius and Ulna Bones Anatomy – Introduction
The radius and ulna are the bones of the forearm. The forearm is the region of the upper limb that extends from the elbow to the wrist.

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.

Carpal Bones: Anterior (Palmar) View
An interactive and illustrated tutorial on carpal bones (Scaphoid, Lunate, Triquetral, Pisiform, Trapezium, Trapezoid, Capitate & Hamate).

Metacarpal Bones: Anterior (Palmar) View
The metacarpal bones include five bones found in palm of hand. Numbering 1 to 5 of bones begins on thumb side.

Phalanges (Phalanx Bones): Anterior (Palmar) View
Each finger consists of three phalanges: Proximal phalanges, middle phalanges, and distal phalanges The thumb only has two: Proximal phalanges and distal phalanges.
