Microscopic examination indicates that the "white" matter regions are characterized by a multilamellar sheath (myelin) which sur rounds the axons. A morphologically similar myelin imparts the white color to tracts of the peripheral nervous system, although, as is empha sized throughout the book, there are very significant morphological and chemical differences between central and peripheral myelin. The rapid postnatal accumulation of myelin is temporally associated with increasing functional capacity and presumably indicates some important role related to neuronal activity. The ability of myelinated axons to conduct electrical impulses much more rapidly and with much lower use of energy, relative to unmyelinated axons, is now generally accepted. As is evident from the above capsule description, a considerable body of information concerning myelin is available. However, as in other areas of research the unknown expands before us more rapidly than we are able to add to our core of knowledge. This is a corollary of the axiom that | | 出版日期 | Book 1977 | | 关键词 | brain; myelin; nervous system; neurons; spinal cord | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4615-7514-6 | | isbn_softcover | 978-1-4615-7516-0 | | isbn_ebook | 978-1-4615-7514-6 | | copyright | Springer Science+Business Media New York 1977 |
