ABSTRACT
There is little information about blood supply of the carpal joint in one- humped camel, while there is extensive data about cow and equine species. In order to perform surgeries and diagnostic techniques in carpal region, information about the elements of the joint such as its arteries is necessary. This study aims at describing the origins, arrangements, and branches of the arterial supply of the carpal joint of the adult one-humped camel [Camelus dromedaries]. Twelve left forelimbs of camelus Dromedrus without any lameness history were divided into 3 equal groups randomly. The brachial artery, before the elbow joint, was injected with warm water containing red gelatin, red latex solution, and rodopas resin solution separately; then, the arterial supply of the carpal joint was studied. The results showed that the radial, median, and caudal interosseous arteries and their branches supplied the carpal joint. [Supplied the carpal joint] Our findings showed that radial artery and its branches such as dorsal and palmar carpal branches were the most important arteries that supply the carpal joint. Median and caudal interosseous arteries support supplying this joint too but the arterial branches supplying the carpal joint in the Bactrian camel are from the radial artery and dorsal interosseous ante-brachium branches. In the cow, the common interosseous, median, collateral ulnar and radial arteries give off branches to supply the carpal joint while common interosseous, median, transverse cubital and radial arteries give off branches to supply the this joint in the horse
ABSTRACT
Background: Considering differences in head size and shape of different Equine breeds, biometric parameters can be an attribute to a particular race
Objectives: The purpose of the present paper is to give a numerical definition of morphological characteristics of head region of the Darehshori horse
Methods: Twenty mature Darehshori horses were studied biometrically. The ear length, ears distance, eyes distance, head length, lateral head length, head width, rostrum length, distance between two mandibles and lateral face length were measured and the averages were calculated
Results: The average of the related characters were as follow; ear length 16.89, ears distance 12.12, eyes distance 15.79, head length 55.26, lateral head length 49.33, head width 20.42, rostrum length 23.68, distance between two mandibles 10.82 and lateral face length 39.88 centimeter
Conclusions The coefficient of variation of these characters showed that the head length, lateral face length and lateral head length are more reliable characters than the other indices in characterizing the Darehshori horse
