PURPOSE To report a rare case of painful trigeminal neuropathy after lateral medullary infarct and probe its underlying pathogenesis on the basis of neuroimaging and electrophysiological study. CASE REPORT A 45-year-old man presented acute onset of unsteady gait followed by paroxysmal and electric shock-like headache in the distribution of ophthalmic branch of left trigeminal nerve in 2 days....

OBJECTIVE To determine systematically the pattern of the cutaneous perforator of the lateral circumflex femoral artery (LCFA) in anterolateral thigh perforator (ALT) flap. MATERIAL AND METHOD Sixty dissections of the LCFA were carried out in 30 preserved cadavers. The number; type, origin, and location of the cutaneous perforators of the LCFA were studied and measured. RESULTS There were 16...

Mutations in the gene unc-53 of Caenorhabditis elegans result in behavioral and anatomical abnormalities. Immunocytochemistry and electron microscopy revealed neuroanatomical defects in all main longitudinal nervous tracts. Whole tracts were found to be misguided in specific ways suggesting that unc-53 affects pioneering axons. The four lateral microtubule cells (LMs), which are probably pionee...

Axillary artery is one of the most important arteries of the upper limb, which is a continua- tion of the subclavian artery. It begins at the lateral border of the first rib and ends at the inferior border of the teres major where it becomes the brachial artery. Axillary artery has six important branches included: 1) Superior thoracic artery 2) Thoracoacromial artery 3) Lateral thoracic artery ...

BACKGROUND The surgical treatment of occipital headaches focuses on the greater, lesser, and third occipital nerves. The lesser occipital nerve (LON) is usually transected with relatively limited available information regarding the compression topography thereof and how such knowledge may impact surgical treatment. METHODS Eight fresh frozen cadavers were dissected focusing on the LON in rela...

The Mauthner (M-) cell of the goldfish, Carassius auratus, triggers the rapid escape response of the fish in response to various stimuli, including visual and auditory. The large size and accessibility of the M-cell make it an ideal model system for the study of synaptic transmission, membrane properties, and sensory-motor gating. Although physiological recordings have suggested that afferents ...

Sural nerve supplies skin on the lower lateral part of the back of the leg, the lateral margin and adjoining part of dorsum of the foot and the lateral side of the little toe. The sural nerve is the branch of tibial nerve and it arises in the middle of the popliteal fossa. The present study aims to determine the pattern of the cutaneous distributions of sural nerve of the dorsum of the foot. Su...
