Simunic DI, Robertson PA, Broom ND: Mechanically induced disruption of the healthy bovine intervertebral disk. Results: The lymphatic system in the canine forelimb was divided into two superficial lymphosomes (ventral cervical and axillary) and one deep lymphatic system. The aim of the study is to determine the age related changes in the skeleton of the forelimb of dogs using This latter connection is sometimes called the girdle muscles, although this is a problematic term, because many of its constituent muscles do not attach to a limb girdle muscle. and transmitted securely. Several forelimb muscles of the fox squirrel show significantly higher mean contraction times than do the homologous muscles of the prairie dog.

Modern comparative anatomy dates from the work of French naturalist Pierre Belon, who in 1555 showed that the skeletons of humans and birds are constructed of similar elements arranged . through the thorax of a horse.
