The subumbrella of the hydrozoan jellyfish Aequorea victoria (previously classified as Aequorea aequorea) is divided by numerous radial canals and attached gonads, so the subumbrellar musculature is partitioned into subumbrellar segments. The ectoderm of each segment includes two types of muscle: smooth muscle with a radial orientation, used for local (feeding and righting) and widespread (prot...

The adductor pollicis muscle was studied in fifty hands of Japanese adult cadavers of both sexes. The radial portion of the oblique head of the adductor pollicis muscle has carpal and metacarpal origins and an insertion into the wing tendon of the extensor apparatus. This portion was located dorsal to the palmar metacarpophalangeal articular nerve and superficial palmar metacarpal artery. Thus,...

OBJECTIVE To investigate the anatomic relationship between the superficial radial nerve (SRN) and the cephalic vein (CV) through ultrasonography due to the possibility of SRN injury during cephalic venipuncture. METHODS Both forearms of 51 healthy volunteers with no history of trauma or surgery were examined in proximal to distal direction using ultrasonography. We measured the distance betwe...

UNLABELLED Study the morphology of the superficial branch of the radial nerve (SBRN) of the forearms and wrists of fresh adult human cadavers. METHODS Twenty three dissections were performed under 3.5x loupe magnification, histological sections of the nerve were obtained in 20 dissections for fascicle identification. RESULTS The SBRN emerged, in average, at 8.65cm proximal to the radial sty...

Introduction: Blood supply to the arm and forearm is conveyed by brachial artery its branches, radial ulnar artery. Variations in these arteries are being increasingly reported many studies. Most of variations observed mostly course branching pattern have been accounted be due developmental defect, from varied causes. 
 Materials Methods: In present study dissection was done on fifty seven...

BACKGROUND Correction of a distal radius fracture malunion is challenging technically. These malunions most classically deform dorsally, but often the deformity involves three planes. METHODS Using an anatomically designed radial plate that takes into consideration the three planes, correction of the deformity can be obtained. In this video we see a patient with a classic dinner fork deformit...

INTRODUCTION Radial nerve compression by a ganglion in the radial tunnel is not common. Compressive neuropathies of the radial nerve in the radial tunnel can occur anywhere along the course of the nerve and may lead to various clinical manifestations, depending on which branch is involved. We present two unusual cases of ganglions located in the radial tunnel and requiring surgical excision. ...

BACKGROUND Anatomically, it is difficult to give a systematic description of the superficial branch of the radial nerve (SBRN). Our aim was to describe the exact relationship of the SBRN to fixed bony points of radial styloid and Lister's tubercle, and to the cephalic vein. We also compared our data with other international studies. METHODS The study was a descriptive anatomical study. Twenty...
