| limb-kinetic apraxia | An inability to make movements or to use objects for the purpose intended. Synonym: cortical apraxia, innervation apraxia, limb-kinetic apraxia. (05 Mar 2000) |

| limb lead | One of the three standard leads (leads I, II, III) or one of the unipolar limb lead's (aVR, aVL, aVF). (05 Mar 2000) |
| limb myokymia | Myokymia present in one or more limbs; various causes, one of the more common being prior plexus radiation. (05 Mar 2000) |
| limb of helix | A transverse ridge continuing backward from the helix of the auricle, dividing the concha into an upper portion (cymba) and a lower portion (cavity of concha). Synonym: crus helicis, crista helicis, limb of helix. (05 Mar 2000) |
| lower limb | The hip, thigh, leg, ankle, and foot. Synonym: membrum inferius, inferior limb, lower extremity, pelvic limb. (05 Mar 2000) |
| bacteria-free stage of bacterial endocarditis | Endocarditis described prior to the antibiotic era and presumably due to spontaneous healing of the bacterial vegetations. (05 Mar 2000) |
| carbon dioxide-free water | Purified water that has been boiled vigorously for 5 minutes or more. (05 Mar 2000) |
| radical, free | In biochemistry, it is a group of atoms bonded together into an entity that is extremely reactive and shortlived. (a free radical is not a political extremist on parole.) (12 Dec 1998) |
| germ-free animal | An animal which has no microorganisms whatsoever living in or on it. An animal which was born and raised in an isolated environment with no microorganisms in it, such as within a germ-free isolator. (09 Oct 1997) |
| germ-free isolator | A chamber which has absolutely no microorganisms whatsoever living in it, where a germ-free animal can be born and raised. An artificial barrier surrounding a living facility for germ-free animals, which keeps out all microorganisms. (09 Oct 1997) |
| germ-free life | Animals not contaminated by or associated with any foreign organisms. (12 Dec 1998) |
| carrier-free | A substance in which a radioactive or other tagged atom is found in every molecule; the highest possible specific activity. (05 Mar 2000) |
| gibbs free energy | The total amount of energy which is either used up or released during a chemical reaction. Gibbs free energy (delta G) = (delta H) - t (delta s): where (delta H) is the change in enthalpy, calculated by adding up the amount of energy released or used up to break or form chemical bonds during the reaction, t is the temperature at which the reaction took place, and (delta S) is the change in entropy, or amount of disorder, that occurs in the molecules involved during the reaction. (09 Oct 1997) |
| mean free path | <radiobiology> Average distance a particle travels between occurrences of the given event, for example, between collisions. For collisions, the mean free path is roughly equal to unity divided by the product of the collision cross-section times the particle density. (09 Oct 1997) |
| cell-free extract | <cell culture> A liquid that is a mixture of the contents of a particular type of cell, sometimes the organelles are also filtered out of the liquid. (26 Mar 1998) |
