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.

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.
Direct control of water excretion in the kidneys is exercised by vasopressin, or anti-diuretic hormone (ADH), a peptide hormone secreted by the hypothalamus. ADH causes the insertion of water channels into the membranes of cells lining the collecting ducts, allowing water reabsorption to occur. Without ADH, little water is reabsorbed in the collecting ducts and dilute urine is excreted.
