The occurrence of anomalous hand muscles in the region of the wrist is a rather common event.Usually authors classify them as accessory abductor digiti minimi (ADM), flexor digiti minimi brevis(FDMB), or palmaris longus [1–12]. This work reports a rarely seen type of accessory muscle. The dissectionwas performed with the permission of the Ethical Committee of Jagiellonian University...

The purpose of this study was to provide a morphologic description and assessment on the formation level of the sural nerve (SN) and its components. Also we aimed to reveal histological features of the SN components.

To describe the radial artery and its variants in origin, branching pattern, mode of termination, and measurements of its length and external diameter.

The portal vein (PV) usually terminates by bifurcating into the right and left PV branches. Other termination patterns include a bifurcation into a common left PV trunk and the right anterior PV trunk; trifurcation; and quadrifurcation [2, 11]. These terminations may be extracapsular, capsular, or intrahepatic [17]. Variations in level and pattern of termination influence the risk of vascular injury during procedures such as hepatectomies, split or living donor transplantation, PV embolisation, and the placement of transjugular intra-hepatic portosystemic shunts (TIPS) [13]...

The comprehensive understanding of variations in tendons of the hand and the fingers is necessary for the proper diagnosis of certain neurological disorders [7]. Among all, the abductor pollicis longus (APL) muscle is one of the most known to present numerous variations. Since there are few reports on such abnormalities in standard anatomy and surgery textbooks, the study of alterations of the APL is of much importance for any academic, surgical and clinical purpose. Variants in the number of tendons of the APL muscle may be asymptomatic and often incidental finding [7, 10, 19, 23]...
