Pathophysiology Of Nerve Entrapment
Nerve compression syndrome, Nerve entrapment involves a cascade of physiological changes caused by compression and tension. Some of these changes are irreversible. The magnitude and duration of the forces determines the extent of injury. In the acute form, mechanical injury and metabolic blocks impede nerve function. In the chronic form, there is a sequence of changes starting with a breakdown of the blood-nerve-barrier, followed by edema with connective tissue changes, followed by diffuse Demyelinating disease, demyelination, and finally followed by axonmetesis. The injury will often be a mixed lesion where mild/moderate compression is a combination of a metabolic block and Neurapraxia, neuropraxia, while severe compression combines elements of neuropraxia and axonmetesis. Peripheral nerve anatomy Nerve cell Neuron, Nerve cells comprise a small cell body and a very long segment called the axon. The cell body resides in the spinal cord and the axon extends all the way to the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross Section Normal Nerve And Atrophied Nerve
A cross is a religious symbol consisting of two Intersection (set theory), intersecting Line (geometry), lines, usually perpendicular to each other. The lines usually run vertically and horizontally. A cross of oblique lines, in the shape of the Latin letter X, is termed a saltire in heraldic terminology. The cross shape has been widely officially recognized as an absolute and exclusive religious symbol of Christianity from an early period in that religion's history.''Christianity: an introduction'' by Alister E. McGrath 2006 pages 321-323 Before then, it was used as a religious or cultural symbol throughout Europe, in West Asia, west and south Asia (the latter, in the form of the original Swastika); and in Ancient Egypt, where the Ankh was a hieroglyph that represented "life" and was used in the wo ...
