It has long served as one of the main evidences for evolution, due to the fact that it is very concrete, and does not require extensive technology. Comparative anatomy is the study of similarities and differences in the anatomy of different species.It is closely related to evolutionary biology and phylogeny (the evolution of species)..

In summary, the striking similarity of many individual structures between the FL and HL was not seen as a major conundrum by earlier non-evolutionary comparative anatomists because they believed that the design of animals followed an "archetype" created by a supernatural or vital power. In the dog, the tibial nerve divides into the area between the crest and the jugular groove cranial medial plantar and larger lateral plantar nerves proximal to the C3C4 articulation. Lesions in the cervical spinal cord or medulla can cause absence of SPECIES-SPECIFIC REFLEXES the cervicoauricular reflex.

Web(2c) There is no difference in fresh bone density between the itypes of dog and horse, but dog bones tend to be more dense than horse bones. Both supply sensation to the fetlock and metatarsus in an arrangement similar to that of the hock joints as well as to the overlying skin. In the horse, the branch of the peroneal nerve supplies the lateral digital tibial nerve can be blocked before its division, approxi- extensor and skin surrounding the lateral tarsus and mately 10 cm above the point of the hock, where it is metatarsus.48 The deep branch of the peroneal nerve of palpable between the tendon of the gastrocnemius and the horse dives between the lateral digital extensor and the deep flexor tendon.39,41,42 In the ox, the tibial nerve the long digital extensor, providing branches to these can be palpated as it courses along the cranial aspect of muscles as well as to the cranial tibial and peroneus ter- the calcanean tendon.1,3 The tibial nerve of the dog can tius muscles.56 As the deep branch continues distally, it be palpated and blocked in the caudal crus, where it becomes a purely sensory nerve that splits into medial runs parallel and cranial to the calcanean tendon.

Accessibility It innervates the supraspinatus and infraspinatus tory function in horses with suspected cervical spinal cord damage. The number of metacarpals varies widely among species, as the demand for their function changes: plantigrade, or flat-footed, animals requiring the full complement of five metacarpal bones; the number is reduced in the upright stature of digitigrade animals such as the dog and cat, and shows the extreme in unguligrades like the horse, which depends entirely on the third metacarpal bone for its stature.
