What is the main function of the cochlea? This action is passed onto the cochlea, a fluid-filled snail-like structure that contains the organ of Corti, the organ for hearing. It consists of tiny hair cells that line the cochlea. These cells translate vibrations into electrical impulses that are carried to the brain by sensory nerves. […]

What the science says: some researchers theorize that humans are reacting to subtle changes in the Earth’s magnetic field that occur […]
When would you use a hypertonic solution?
When would you use a hypertonic solution? Examples of when hypertonic solutions are used include to replace electrolytes (as in hyponatremia), to treat hypotonic dehydration, and to treat certain types of shock. Solutions with a lower concentration of solutes than isotonic solutions are hypotonic. What is 3 hypertonic saline used for? Conclusions: Hypertonic saline administration […]
