The pectoral and pelvic girdles, which articulate with the axial skeleton, together with their associated limbs, the forelimbs and hind limbs, form the appendicular skeleton.[AAO], Skeletal system that consists of the paired fins (pectoral or pelvic fins).[TAO], Skeletal subdivision consisting of all the skeletal elements in the pectoral and pelvic appendage complexes.[VSAO]

ontologies differ in whether they treat the term appendicular skeleton as being the entire set of bones in the limbs, or whether the fore and hind limbs/fins are treated as seperate appendicular skeletons. Here we follow FMA, and treat the appendicular skeleton as the sum total of skeletal elements in the organism (this is evidenced by the fact that in FMA, skeleton of left/right upper/lower limb is part_of a appendicular skeleton, and subtypes of 'subdivision of appendicular skeleton'). We have separate classes such as 'skeleton of limb', and 'skeleton of hindlimb' for the 4 parts of the appendicular skeleton. In future the ZFA/TAO classes may be moved.
