OBJECTIVE: The aim of this study was to investigate the prevalence of anatomic variations of the bifid median nerve, persistent median artery and persistent median vein in Chinese individuals and their relationship with carpal tunnel syndrome. METHODS: One hundred and sixty median nerves were examined using ultrasonography and colour Doppler ultrasonography. The location, shape, and size of t...

The median artery is the main source of blood for the forearm in intrauterine life. During the process of development the median artery gets obliterated and supplies the median nerve. Variation of persistent median artery and its accompanying with the median nerve in the carpal tunnel is one of the important anatomic variations of the upper limb. Thrombosis of the artery inside the carpal tunne...

introduction: the persian squirrel (sciurus anomalus) is considered the only well-known species of the family sciuridae in the middle east. since some people keep this squirrel as a domestic pet, their attendance at veterinary clinics is increasing. so far, no study has been conducted on the arterial supply of the pelvic cavity and limb in the squirrel. hence, this research was performed to fil...

The brachial artery begins as a continuation of the axillary artery and is superficial throughout its course in the arm. When it enters the cubital fossa it lies anterior to the brachialis muscle and lateral to the median nerve. In cubital fossa it lies deep to bicipital aponeurosis which separates the artery from median cubital vein. The median nerve descends along the lateral side of the prox...
