21. Osmolarity is affected by changes in water content, as well as temperature and pressure.22. Increased osmolarity frequently occurs following illness due to chronic neurotoxic diseases such as Lyme disease. 23. This high serum osmolarity stimulates excessive urination. 24. With the newer reduced-osmolarity , more dilute solution, this is not necessary. 25. One cycle takes several seconds, depending on the species and the environment's osmolarity . 26. This condition results in a net concentrating effect on the serum ( increasing its osmolarity ). 27. When these birds consume salt, the osmolarity increases in the blood plasma through the gut. 28. Stated simply, an increase in osmolarity results in a reversible depolarization of the OVLT neurons. 29. For comparison, most marine teleosts have an osmolarity of only around a third of seawater. 30. The osmolarity of the solution of sodium chloride, however, is 308 milliosmoles / liter.
