Now a large and ever increasing number of genetic subtypes has been described, and major advances in molecular and cellular biology have clarified the understanding of the role of different proteins in the physiology of peripheral nerve conduction in health and in disease. (medscape.com)

The mechanism for coma or impaired consciousness involves dysfunction of both cerebral hemispheres or of the reticular activating system (also known as the ascending arousal system). (merckmanuals.com)
Neuropathic pain is defined as the pain resulting from a lesion or dysfunction of somatosensory system and characterized by either spontaneous pain or sensitivity exacerbated to different stimuli 22 . (bvsalud.org)

Claudin-19 (green) helps form tight junction structures that seal PNS myelin sheaths. (rupress.org)
Cancerous lymphocytes that form and grow in the body of a lymphoma patient can travel throughout the lymphatic system and bloodstream. (healthprep.com)

They identified 125 1-α-dendrotoxin as the antagonist that binds to and blocks the channels, causing an intracellular build-up of potassium ions which causes inflammation and irritation, and consequently, hyper-excitability in the peripheral nervous system. (wikipedia.org)

By exploiting the nano-structural ~17 nm repeat pattern typical of myelin sheath, which gives rise to a distinct small angle scattering pattern, tomographic myelin maps in macroscopic tissue volumes were derived ( Fig. 1 ). (stanford.edu)
When a schwannoma tumor develops, it forms around the tissue of the myelin sheath. (cancerworld.info)

In addition to a brain, (d) arthropods have clusters of nerve cell bodies, called peripheral ganglia, located along the ventral nerve cord. (opentextbc.ca)

Three tumours had gain on 17q, which has also been reported in malignant peripheral nerve sheath tumours that are associated with neurofibromatosis type 1. (bmj.com)

The covering of the nerve ( myelin sheath) or part of the nerve cell (the axon) may be damaged. (medlineplus.gov)

The portion of the nervous system that is considered involuntary is the somatic nervous system. (studyinnovations.com)

Just as vitamins are needed for normal nervous system development in children, they are required for normal neurological functioning in adults-young and old. (healthy.net)
