INTRODUCTION The prevalence of bifid median nerves and persistent median arteries, their co-occurrence, and their relationship to carpal tunnel syndrome (CTS) are only understood partially. METHODS We screened 1026 wrists of 513 Latino manual laborers in North Carolina for bifid median nerves and persistent median arteries using electrodiagnosis and ultrasound. RESULTS A total of 8.6% of wr...

Bifid median nerve is an anatomic variation that may be associated with carpal tunnel syndrome. It is important for the surgeon to be aware of the existence of this condition preoperatively in order to plan the carpal tunnel release. We report the correlation between ultrasonographic findings and magnetic resonance imaging results in six patients with bifid median nerve, selected from a populat...

This study was aimed at mapping the organization of the projections from the inferior olive (IO) to the ventral uvula in pigeons. The uvula is part of the vestibulocerebellum (VbC), which is involved in the processing of optic flow resulting from self-motion. As in other areas of the cerebellum, the uvula is organized into sagittal zones, which is apparent with respect to afferent inputs, the p...

There is but little literature descriptive of the microscopic morbid anatomy of the uvula. This is true especially of the condition known as relaxed or elongated uvula. Inman s in 1852 described the uvula in this condition as being " very firm and almost fibrous in the interior, covered with ordinary mucous membrane, which was not hypertrophied. On making sections and teasing with needles, the ...

OBJECTIVE The variation in the anatomy of the iliopsoas tendon is important information for orthopaedic surgeons operating around the hip. The aim of this study was to identify the prevalence of bifid iliopsoas tendons in children on magnetic resonance imaging (MRI). METHODS MRI hip and pelvis images of 50 sequential children aged 7-15 years were retrieved from our radiology database at the E...

We describe two cases of a bifid mandibular condyle. The first case is a 48-year-old woman with headaches and a pain and clicking sensation in her right jaw during mastication. The second case is an asymptomatic 17-year-old woman with a history of bilateral microtia and hemifacial microsomia. In both patients, the bifid condyle was first identified by CT and affected the temporomandibular joint...
