Results: The lymphatic system in the canine forelimb was divided into two superficial lymphosomes (ventral cervical and axillary) and one deep lymphatic system. 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 . This similarity is an example of \\ a. vestig Horse embryos at several stages (20, 50, 350 mm) show one, long, cylindrical dominant digit and two splint metacarpal digits, which commence as cartilaginous precursors that ultimately ossify . Humerus The humerus is essentially the same conformation as that of the dog. The ventral surfaces of these stand for long periods.17 This rigidity may also facilitate vertebrae are grooved for the median caudal artery. 11. This is the supratrochlear foramen. The olecranon articulates with the humerus via its anconeal process. Laterally, the deltoid tuberosity is palpable through the skin and connects to the head of the humerus via a ridge and merges distally with the crest of the humerus. The radius forms the shaft-like rod of the distal limb, which is bowed to varying degrees amongst species. with the wing of the sacrum in the horse.1,8 The six lum- phometry note that the annulus is composed of concen- bar vertebrae of the ox are much longer than those of trically arranged lamellae of type I collagen.12,13 The the horse and are very narrow midbody. A small sesamoid bone embedded in the medial tissues of the joint can sometimes be mistaken as a chip fracture. The forelimb skeleton consists of the thoracic or pectoral girdle and bones of the forelimb (see Figures 5-5 and 5-6). The size of forelimb bones varies a great deal, because of the greater variation in size for breeds of dogs. The forelimbs bear 60% of the dogs weight. The canine scapula is positioned close to the sagittal plane. Win32 Disk Imager Portable, The major nerves that emanate f rom the The axillary nerve supplies motor function to the brachial plexus are the suprascapular, subscapular, mus- teres major, teres minor, deltoideus, and a portion of the culocutaneous, axillary, radial, median, and ulnar nerves subscapularis muscle in all species.1 This nerve may also (Table 1). 286 CE Comparative Anatomy of the Horse, Ox, and Dog Figure 2.

A forelimb or front limb is one of the paired articulated appendages attached on the cranial end of a terrestrial tetrapod vertebrate's torso.With reference to quadrupeds, the term foreleg or front leg is often used instead.

Jansson N: What is your diagnosis? Instructions 1. The uppermost bone in the foreleg is the scapula, or shoulder blade.
