part of part of skeleton of pectoral girdle region appendicular skeleton pectoral girdle skeleton A subdivision of a limb or fin skeleton consisting of bones which connects the upper limb or fin to the axial skeleton on each side. It consists of the clavicle and scapula in humans and, in those species with three bones in the pectoral girdle, the coracoid. Some mammalian species (e.g. the dog and the horse) have only the scapula. In humans, the only joints between the shoulder girdle and axial skeleton are the sternoclavicular joints on each side. No joint exists between each scapula and the rib cage; instead the muscular connection between the two permits relatively great mobility of the shoulder girdle in relation to the pelvic girdle. In those species having only the scapula, no joint exists between the forelimb and the thorax, the only attachment being muscular[WP]. Examples: There are only two instances, right and left pectoral girdle skeletons. skeleton of pectoral girdle NCIT:C33547 AAO:0000422 XAO:0003063 scapular girdle UBERON:0007831 EFO:0000946 ZFA:0000407 MIAA:0000181 VSAO:0000156 MAT:0000181 TAO:0000407 AAO:0000754 Wikipedia:Pectoral_girdle skeletal parts of pectoral girdle VHOG:0001156 FMA:24141 EHDAA2:0001420 girdle skeleton subdivision of skeleton skeleton of pectoral complex
