Preferred Label : pectoral girdle skeleton;
Uberon definition : 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.;
Uberon synonym : skeleton of pectoral girdle; skeletal parts of pectoral girdle;
Uberon related term : pectoral girdle; scapular girdle;
Uberon Homology note : The pectoral girdle is clearly of dual origin, composed of dermal as well as endochondral
bones. The endochondral component, the scapulocoracoid, evolved by fusion or enlargment
of several basal fin elements. (...) The dermal component of the shoulder girdle evolved
from dermal bones of the body's surface. (...) Like endochondral bones, these dermal
bones were passed along to tetrapods (...).[well established][VHOG];
