Which part of the upper limb skeleton consists of the manubrium sterni, body, and xiphoid process?

Axial Skeleton

The axial skeleton consists of the skull, vertebral column, ribs, and sternum.
The vertebral column consists of 7 cervical, 12 thoracic, 5 lumbar, 5 fused sacral, and 3-4 fused coccygeal vertebrae.
There are 12 pairs of ribs, and the sternum is located in the midline.

Thoracic Cage

The thoracic cage consists of the sternum, ribs, and thoracic vertebrae.
The sternum is formed of the manubrium, body, and xiphoid process.
The sternal angle is a landmark formed by the junction between the manubrium and the body, located at the level of the second costal cartilage and the second rib.

Ribs

There are 12 ribs on each side, classified into:
- True ribs: Upper 7 ribs attached to the sternum
- False ribs: Lower 5 ribs not attached to the sternum
- Floating ribs: The lower 2 ribs that are free anteriorly

Thoracic Vertebrae

There are 12 thoracic vertebrae that form the posterior part of the thoracic cage.
They articulate with each other by intervertebral discs.

Appendicular Skeleton

Upper Limb

The skeleton of the upper limb consists of:
- Shoulder girdle/pectoral girdle: Clavicle (anterior) and scapula (posterior)
- Arm: Humerus
- Forearm: Radius (lateral) and ulna (medial)
- Hand: Carpal bones (proximal), metacarpals (intermediate), and phalanges (distal)

Lower Limb

The skeleton of the lower limb consists of:
- Pelvic girdle: Hip bone
- Thigh: Femur
- Leg: Tibia (medial) and fibula (lateral)
- Foot: Tarsus (proximal), metatarsus (intermediate), and phalanges (distal)
