Arterial distribution to the tensor fasciae antebrachii muscle: a study in dogs, cattle, pigs, and horses

Arterial distribution to the tensor fasciae antebrachii (TFA) muscle is little described in the veterinary literature. In this study, we investigated TFA vascularity intra- and inter-specifically, using specimens obtained from dogs, cattle, pigs, and horses at necropsy. Canine TFA specimens showed vascularity from the collateral ulnar artery in all cases, and from the thoracodorsal artery in some cases, with no brachial or deep brachial arterial vascularity. Bovine TFA specimens showed vascularity from the thoracodorsal artery. All porcine TFA specimens showed deep brachial arterial vascularity. Equine TFA specimens showed strong subscapular arterial vascularity, as well as some supply from branches of the deep brachial artery. This article will encourage further active research.
