The horse skeleton is the rigid framework of the body that consists of bones, cartilages, and ligaments.There are two hundred and five bones found in horse skeleton.In this long article, I will discuss the osteological features of all bones from the horse skeleton anatomy labeled diagram. Am J Vet Res 51:264267, 1990. 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.

It is bounded medially and laterally by collateral ligaments between the humerus and radius, caudally by the olecranon ligament between the humerus and olecranon, and further enforced by the annular radial ligament.

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. species. 26.

The head has been skinned and most of the cutaneous musculature has been removed except that on the muzzle (compare with Figs 2.27- 2.30 of the dog). While structurally it is a ball and socket joint, it functions as a hinge joint due to extensive muscling around the articulation. nerve can be palpated as it runs over the medial collateral In the ox, the median nerve follows the median artery ligament of the elbow and can be blocked at this point, through the carpal canal before dividing into medial and generally 5 cm distal to the elbow, proximal to the origin lateral branches.
