body surface area (BSA)
the total surface area of the body. Used to calculate drug dosages, particularly in the use of toxic drugs such as those used in cancer chemotherapy. This minimizes errors introduced by variations in distribution, metabolism and excretion of the drug. Several equations can be used to express the area, based on body weight, but conversion tables are usually used. See Table 21.
transverse ridge crossing the ventral surface of the medulla oblongata.
the transparent gel filling the posterior segment of the eyeball between the lens and retina. Called also vitreous and vitreous humor.
