axon) The anatomy and action of a nerve cell. The nerve cell or neuron consists of a cell body with the nucleus and projections called dendrites which pick up messages. An extension of the cell, the axon, connects one cell to the dendrites of the next. When a nerve cell is stimulated, waves of sodium (Na+) and potassium (K+) ions carry an electrical impulse down the axon. Long threadlike extension of a nerve cell that conducts electrochemical impulses away from the cell body towards other nerve cells, or towards an effector organ such as a muscle. Axons terminate in synapses, junctions with other nerve cells, muscles, or glands. How to thank TFD for its existence?

A new device that applies shrink sleeves to blow molded or thermo-formed containers at 300/min comes from Axon Corp. Waxman's early research showed that when the axon's protective myelin sheath is damaged, as happens in MS, the exposed parts of the axon don't contain enough sodium channels to power nerve conduction. |
