  1. Bones of the Upper Limb: A Comprehensive Overview This presentation explores the intricate structure and function of the bones comprising the upper limb, from the shoulder to the fingertips. J. ALOSIOUS IRUDHAYA QUBET 1ST YEAR’S B. SC DT

  2. The Pectoral Girdle: Foundation of Movement Clavicle (Collarbone) Scapula (Shoulder Blade) The clavicle is an S-shaped bone that connects the shoulder blade to the sternum. The scapula is a triangular bone that sits on the back of the rib cage, allowing for a wide range of arm movements.

  3. The Arm: Connecting Shoulder to Forearm Humerus Articulation 1 2 The humerus is the long bone of the upper arm, connecting the shoulder joint to the elbow. The humerus articulates with the scapula at the shoulder joint and the radius and ulna at the elbow joint.

  4. The Forearm: Two Bones, Many Movements Radius Ulna The radius is the shorter and thicker bone of the forearm, located on the thumb side. The ulna is the longer bone of the forearm, located on the pinky side.

  5. The Wrist: A Complex Network of Bones Proximal Row 1 2 Distal Row 3 8 Carpal Bones

  6. The Palm: Supporting the Hand 5 Metacarpal Bones 1 These long bones form the framework of the palm. Articulation They articulate with the carpal bones of the wrist at the proximal end and the phalanges of the fingers at the distal end. 2

  7. The Fingers: Flexibility and Dexterity 3 2 Phalanges Thumb Each finger (except the thumb) has three phalanges: proximal, middle, and distal. The thumb has only two phalanges: proximal and distal.

  8. Bone Functions: Structure and Movement Provide structural support, forming the framework of the limb. 1 Enable a wide range of movements, including flexion, extension, rotation, and grasping. 2 Protect vital internal organs, such as the nerves and blood vessels. 3

  9. Common Upper Limb Fractures and Injuries Fractures Common fractures occur in the clavicle, humerus, radius, ulna, and metacarpals. Dislocations Dislocations are most common in the shoulder and elbow joints. Sprains Sprains are common in the wrist and hand, involving ligaments.

  10. Importance of Proper Bone Health Diet Exercise Prevention Consume calcium-rich foods and vitamin D for bone strength. Engage in weight-bearing activities and regular physical activity to promote bone density. Protect your upper limbs from injury by taking precautions in sports and daily activities.
