The Human Skeleton can be divided up into two parts, the axial Skeleton, and the appendicular skeleton. The central part of the body contains the axial skeleton, and the bones lying along a central axis of the body are the appendicular skeleton. Axial Skeleton The axial skeleton contains 80 bones. 29 bones in the head […] The appendicular skeleton comprises the upper and lower extremities. The shoulder and hip are important limb segments connecting the appendicular and axial skeleton, essential for mechanical load transfer. Of the 206 bones in the adult human body, 126 form the appendicular skeleton. The appendicular skeleton is composed of the bones of the upper limbs (which function to grasp and manipulate objects) and the lower limbs (which permit locomotion). It also includes the pectoral girdle, or shoulder girdle, that attaches the upper limbs to the body, and the pelvic girdle that attaches the lower limbs to the body. The appendicular skeleton enables movement and interaction with the environment, making it vital for daily activities. Its design supports a wide range of motions, from walking to precise hand movements.
