a skeletal support to which the forelimbs of vertebrates are attached
the bony or cartilaginous arch that supports the forelimbs of a vertebrate
In humans, the bony arch by which the arms are attached to the rest of the skeleton; composed of the clavicle and scapula. PICTURE
The skeletal support for the anterior limbs of vertebrates that transmits power from limbs to the body and also serves to protect and support the organs in the thorax.
The pectoral girdle is the set of bones which connect the upper limb 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. dog and horse) have evolved to have only the scapula.
