| free margin | Unattached edge of a sturcture, often opposite the attached edge. See: free border of nail, free border of ovary. Synonym: margo liber, free margin. (05 Mar 2000) |
| free margin of eyelids | The unattached inferior edge of the upper lid and superior edge of the lower lid, where the anterior (cutaneous) surface of the eyelid meets the posterior (conjunctival) surface of the eyelid. The free margins of the eyelids bound the rima palpebrarum, and each free margin has an anterior and posterior border. See: borders of eyelids. (05 Mar 2000) |
| free-milling | Yielding free gold or silver; said of certain ores which can be reduced by crushing and amalgamation, without roasting or other chemical treatment. Source: Websters Dictionary (01 Mar 1998) |
| free nerve endings | A form of peripheral ending of sensory nerve fibres in which the terminal filaments end freely in the tissue. Synonym: terminationes nervorum liberae. (05 Mar 2000) |
| free radicals | Highly reactive molecules with an unsatisfied electron valence pair. Free radicals are produced in both normal and pathological processes. They are proven or suspected agents of tissue damage in a wide variety of circumstances including radiation, damage from environment chemicals, and aging. Natural and pharmacological prevention of free radical damage is being actively investigated. (12 Dec 1998) |

| free tenia | See: teniae coli. Synonym: tenia libera. (05 Mar 2000) |
| free thyroxine index | An arbitrary value obtained by multiplying the triiodothyronine uptake by the serum thyroxine concentration; it largely corrects for variations in thyroid-bound globulin concentration by providing a clinically valid estimate of the physiologically active free thyroxine; direct assay or laboratory measurement of free serum thyroxine yields a more accurate value.

| free villus | A chorionic villus that is not attached to the decidua basalis, but is "free" in the maternal blood of the intervillous spaces. Synonym: floating villus. (05 Mar 2000) |
| free water | Water in the body that can be removed by ultrafiltration and in which substances can be dissolved. (05 Mar 2000) |
| free water clearance | The amount of water excreted in the urine beyond that which would accompany the excreted solutes if the urine were isosmotic with plasma; it represents the loss of body water in excess of solute tending to raise body osmolality and making urine hyposmotic. Unlike other clearance's, it is calculated by subtracting the osmolal clearance from the actual volume of urine excreted per minute. A negative value for free water clearance represents the amount of water that the body has reclaimed from isosmotic tubule fluid to make the urine hyperosmotic and to lower body osmolality.
