Thus, the concentration gradient promotes the movement ofK + which increases the electrical gradient but the electrical gradient inhibits further movement of K+. They do so by wrapping around the long fibers.The insulation properties come from myelin contained within the cells.The layer of insulation is referred to as a myelin sheath.If these insulating cells are located in the peripheral nervous system, they are called Schwann cells.Terms that are used to describe structures found in both the CNS and PNSYou will be responsible for learning the terms used for the peripheral nervous system in the table below

Both gates must be in their permissive positions for the channel to conduct ions, but closure of either gate precludes ion flow.An ion pump can similarly be viewed as an ion-selective pathway, but one to which access is controlled by two gates whose opening and closing is timed so that they are never both open simultaneously3 (Fig. The direction ions move in depends on the sign of their charge, the magnitude and direction of their transmembrane concentration gradient, and the size and sign of the transmembrane electric potential difference

The result is that these channels open only when the electrochemical gradient is outward, such that their opening will only allow protons to leave cells.

How Reverse Osmosis Water Filter Systems Work and What They Do
http://espwaterproducts.com/about-reverse-osmosis.htm Competition: low
Has the manufacturer used sound methods? What types of welds have been used in these plastic products? Will they allow contaminated water to bypass the filtration system? Will they allow the system to leak? How has this filter or membrane been created? Will it allow the water to 'channel' and, in effect, bypass the removal component of this device? What about the quality of the 'fill'? Are it's contents of a high enough quality to produce the expected percentage of contaminant reduction? Carbon quality, for instance, can have huge variances in reduction capability, reduction capacity, and the sloughing of 'fines', which can prematurely clog or foul the RO Membrane. Once water is drawn from the RO drinking water faucet, the pressure in the tank drops and the shut off valves opens, allowing water to flow to the membrane and waste-water (water containing contaminants) to flow down the drain

These are not static volumes, but represent the net effects of dynamic fluid exchange with varying turnover rates between compartments (Guyton and Hall, 2000).

Water Hardness Map (Click for larger image) How to Size the Water Softener Picking the right water softener is an important step in the purification of your water To understand sizing, it is best to understand how it all works.

http://en.wikipedia.org/wiki/NaKATPase Competition: low
For instance, Na+-K+-ATPase found in the membrane of heart cells is an important target of cardiac glycosides (for example digoxin and ouabain), inotropic drugs used to improve heart performance by increasing its force of contraction. Since this carrier enzyme (Na+-Ca2+ translocator) uses the Na gradient generated by the Na+-K+ pump to remove Ca2+ from the intracellular space, slowing down the Na+-K+ pump results in a permanently elevated Ca2+ level in the muscle, which may be the mechanism of the long-term inotropic effect of cardiac glycosides such as digoxin
