Upper limb weight is transmitted to axial skeleton by all except
**Core Concept**
The transmission of upper limb weight to the axial skeleton is a crucial aspect of maintaining posture and facilitating movement. This is primarily achieved through the skeletal system, where forces from the upper limbs are dispersed through the scapula, clavicle, and humerus to the axial skeleton.
**Why the Correct Answer is Right**
The correct answer involves understanding the anatomy and biomechanics of the shoulder girdle and upper limb. The scapula, clavicle, and humerus form a complex structure that allows for a wide range of motion while maintaining stability. The scapula plays a key role in transmitting forces from the upper limb to the thoracic spine. The clavicle serves as a strut, connecting the scapula to the sternum, and helps to distribute forces from the upper limb to the axial skeleton. The humerus, while not directly transmitting forces to the axial skeleton, is an essential component of the upper limb that helps to distribute forces to the scapula and clavicle.
