This frame has 48 mm lenses and a 24 mm bridge. Sometimes measurements will be written on the bridge tabs, especially on clear frames or women's frames. This one has a 46 mm lens width and an 18 mm bridge.Sometimes measurements will be written on the bridge tabs, especially on clear frames or women's frames. This one has a 46 mm lens width and an 18 mm bridge. On the temples, you'll see ''4 1/2 5 3/4'' or sometimes just ''7'', which is the longest temple I've found.ometimes measurements will be written on the bridge tabs, especially on clear frames or women's frames.

Increase in permeability of the cells of the collecting tubule to water is due to an increase in the production of antidiuretic hormone (ADH).   Aquaporins are constant com â¦ ponents of the tubule cells membranes. Unless ADH is present, aquaporins are virtually absent in the luminal membranes of the collecting duct.
The principal action of ADH is to regulate the amount of water excreted by the kidneys. As ADH (which is also known as vasopressin) causes direct water reabsorption from the kidney tubules, salts and wastes are concentrated in what will eventually be excreted as urine. The hypothalamus controls the mechanisms of ADH secretion, either by regulating blood volume or the concentration of water in the blood.
