sodium - definition of sodium in the Medical dictionary - by the Free Online Medical Dictionary, Thesaurus and Encyclopedia.
http://medical-dictionary.thefreedictionary.com/sodium Competition: low
(See Appendix 6.) Sodium is the major cation of the extracellular fluid, constituting 90 to 95 per cent of all cations in the blood plasma and interstitial fluid; it thus determines the osmolality of the extracellular fluid. Sodium bicarbonate, which is very effective in rendering the urine alkaline, is an ingredient in many solutions used as douches, mouthwashes, and enemas

This action obstructs the movement of nerve impulses near the site of injection, but there are no changes in awareness and sense perception in other areas. Oliver Wendell Holmes coined the term "anesthesia" in 1846 to describe drug-induced insensibility to sensation (particularly pain), shortly after the first publicized demonstration of inhaled ether rendered a patient unresponsive during a surgical procedure

This sole flows through more than 56,000 miles of waterways and blood vessels throughout our organism with the forces of gravity and levity and regulates and balances the functions of our body.

If we increase the stimulus (e.g., from 0.5 volt to 1 volt), what happens to the rate at which action potentials (and impulses) occur? Because 1 volt is an above-threshold stimulus, it means that, once an actional potential has been generated, another one will occur in less than 20 ms or, in other words, before the end of the relative refractory period. OVERALL, therefore, there are lots of positively charged potassium ions just inside the membrane and lots of positively charged sodium ions PLUS some potassium ions on the outside

Athletes can restore sodium levels with foods that have lower levels of sodium, such as beets, chicken, nuts, fish, milk, carrots, cauliflower and celery. In addition to helping the heart and muscles stay on track, this necessary mineral also supports proper function of the nerve cells, heart valves and kidneys

Photoreceptors Detect Vision and Light Sensitivity The human eye can detect light in the 400-700 nanometer (nm) range, a small portion of the electromagnetic spectrum, the visible light spectrum. Eventually enough potassium ions pass to the outside to restore the membrane charges to those of the original resting potential.The cell begins then to pump the ions back to their original sides of the membrane
