Appendicular Skeleton: Meaning, Diagram, Functions Appendicular Skeleton: A human body is made up of approximately 206 to 213 different bones. These bones are part of the skeleton that helps us in every movement and the organs in our body. The skeleton or the bone structure is of two categories: Axial skeleton and Appendicular skeleton. Learn about the bones of the shoulder girdle, upper limbs, pelvis, and lower limbs that form the appendicular skeleton. See 3D models, mnemonics, and adaptations of the female and male pelvis. 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.
