The organization of autonomic nerve structures in the large intestine of chinchilla was investigated using histochemical and immunocytochemical methods. The myenteric plexus formed network nodes of cholinergic neurocyte agglomerations connected with bundles of nerve fibres and localized between the circular and longitudinal layers of the smooth muscles. The highest density of myenteric plexus w...

The brachial plexus is a complex anatomical structure that links the cervical spine with muscles and dermatomes of the arm. An expert neurodiagnostic system, PlexusDx, has been developed to assist in the diagnosis of brachial plexus legions. This is part of a larger neuro-diagnostic system called Neurobridge. Benchmarks for lesions of the plexus were created and tested against diagnoses of vari...

Using MR imaging, the authors detected 23 cases of intracranial lipomas, among which were three cases of solitary choroid plexus lipomas. All the lipomas were located in the choroid plexus at the trigone. One of the three solitary choroid plexus lipomas was very small and could not be detected using CT. The authors believe that solitary choroid plexus lipomas are not as rare as was previously t...

The choroid plexus, located in brain ventricles, has received surprisingly little attention in clinical neuroscience. In morphometric brain analysis, we serendipitously found a 21% increase in choroid plexus volume in 12 patients suffering from complex regional pain syndrome (CRPS) compared with age- and gender-matched healthy subjects. No enlargement was observed in a group of 8 patients suffe...

he Brachial plexus constitute afferent motor and efferent sensory nerves supplying the upper extremities. It is situated in a very vulnerable T anatomical position between the neck and shoulder. Injury to this plexus, which is often due to traction, results in various degrees of motor and sensory deficit to the involved upper limb. This results in loss of function and its catastrophic consequen...

Regional anesthetic block of the cervical plexus is a safe and useful alternative to general endotracheal anesthesia for surgery of the neck, upper shoulder, and occipital scalp area. The sensory component of the cervical plexus can be blocked separately and easily by a superficial cervical plexus block. Both motor and sensory block can be obtained by deep cervical plexus block. Minor transient...

Infiltrating T cells and monocyte-derived macrophages support central nervous system repair. Although infiltration of leucocytes to the injured central nervous system has recently been shown to be orchestrated by the brain's choroid plexus, the immunological mechanism that maintains this barrier and regulates its activity as a selective gate is poorly understood. Here, we hypothesized that CD4(...

BACKGROUND Although all published studies investigating the association between nailfold plexus visibility and schizophrenia have found the subpapillary plexus (the vascular network into which capillaries drain) to be unusually visible in many schizophrenia patients, little else is known about this putative marker for schizophrenia liability. METHODS Plexus visibility was rated in 63 chronic ...

Rationale Knowledge of the relationship of the dorsal scapular artery (DSA) with the brachial plexus is limited. Objective We report a case of a variant DSA path, and revisit DSA origins and under-investigated relationship with the plexus in cadavers. Methods The DSA was examined in a male patient and 106 cadavers. Results In the case, we observed an unusual DSA compressing the lower plexus tru...

Choroid plexus papillomas are rare, benign tumors originating from the choroid plexus. Although generally found within the ventricular system, they can arise ectopically in the brain parenchyma or disseminate throughout the neuraxis. We sought to review recent advances in our understanding of the molecular biology and oncogenic pathways associated with this disease. A comprehensive PubMed liter...
