Background: The median nerve is one of the most important branches of the brachial plexus. Due to the role of the median nerve in sensory and motor innervation of the forearm and hand in the upper limbs, its blood supply is very important. Awareness of variations in the blood supply pattern to this nerve reduces the incidence of necrosis and ischemia of the nerve during surgical and diagnostic ...

PURPOSE It is still largely unknown how neural tube defects in spina bifida affect the nerves at the level of the sacral plexus. Visualizing the sacral plexus in 3 dimensions could improve our anatomical understanding of neurological problems in patients with spina bifida. We investigated anatomical and microstructural properties of the sacral plexus of patients with spina bifida using diffusio...

Although supraclavicular brachial plexus block (SCBPB) was repopularized by the introduction of ultrasound, its usefulness in shoulder surgery has not been widely reported. The objective of this study was to compare motor and sensory blockades, the incidence of side effects, and intraoperative opioid analgesic requirements between SCBPB and interscalene brachial plexus block (ISBPB) in patients...

22 Somatosensory signals undergo substantial modulation in the dorsal column nuclei. We examined transmission 23 of signals from forelimb afferents in primate cuneate and external cuneate nuclei. In anaesthetised macaque 24 monkeys, the median, ulnar, deep radial and superficial radial nerves were electrically stimulated at 1.5-2x 25 motor threshold with independent Poisson trains whilst extrac...

BACKGROUND Upper limb disorders (ULDs) are common, and so are the difficulties with regard to their specific diagnoses. According to diagnostic consensus criteria, specific diagnoses include neuropathy and muscular- and connective-tissue disorders (MCDs). There is a need for valid objective diagnostic tools to reveal underlying mechanisms for specific diagnoses. OBJECTIVE To investigate the p...

INTRODUCTION BACKGROUND: Nerve conduction studies (NCS) which assess peripheral nerve functions and their parameters, are known to vary with anthropometric measurements. OBJECTIVE: To study the effect of height on the NCS variables in the peripheral nerves of the limbs. SETTINGS AND DESIGNS: Department of Physiology, normative. METHODS AND MATERIAL: This study was done on 34 (age: 31.24±11.57 y...

Abstract Background Obesity is now a worldwide health problem that predisposes to development of numerous complications, one which peripheral neuropathy (PN). Elevated interleukin-6 (IL-6) cytokine levels associating the chronic inflammatory state in obesity thought play major role complications. Methods We conducted Cross-sectional study on 30 obese patients and 10 matched healthy lean control...

this study was conducted on 48 specimens of rectus abdominis muscles for recognition and definition of passage and ramification of lower intercostal nerves. the main results of this study are as follows: 1- the seventh and eight intercostal nerves penetrated to posterior layer of the rectus sheath while other intercostal nerves perforated to dorsal layer of internal oblique abdominis aponeurosi...
