| equilibrium constant | <chemistry> The ratio of the reverse and forward rate constants for a reaction of the type: A + B = AB at equilibrium the equilibrium constant (K) equals the product of the concentrations of reactants divided by the concentration of product and has dimensions of concentration. Kd = (concentration A.concentration B) / (concentration AB). The affinity constant (Ka) is the reciprocal of the equilibrium constant. Dimension: moles per litre. In general the concept of Kd is more readily understood than that of Ka, for example: in considering the conversion of A to AB by the binding of ligand B, the Kd = B when A = AB. Thus Kd is equal to the ligand concentration which produces half maximal conversion (response). (10 Jan 1998) |

| equilibrium dialysis | In immunology, a method for determination of association constants for hapten-antibody reactions in a system in which the hapten (dialyzable) and antibody (nondialyzable) solutions are separated by semipermeable membranes. Since at equilibrium the quantity of free hapten will be the same in the two compartments, quantitative determinations can be made of hapten-bound antibody, free antibody, and free hapten.

| equilibrium potential | <physiology> The membrane potential at which a particular type of ion or other particle does not diffuse through the membrane in either direction. (09 Oct 1997) |
| linkage equilibrium | <genetics> Situation that should exist in a population undisturbed by selection, migration, etc., in which all possible combinations of linked genes should be present at equal frequency. The situation is no more common than are such undisturbed populations. (18 Nov 1997) |

| visceral sense | The perception of the existence of the internal organs. Synonym: seventh sense, splanchnesthesia, splanchnesthetic sensibility. (05 Mar 2000) |
| weight sense | The faculty of discriminating various degrees of pressure on the surface. Synonym: baresthesia, piesesthesia, weight sense. (05 Mar 2000) |
| colour sense | The ability to perceive variations in hue, luminosity, and saturation of light. (05 Mar 2000) |
| muscular sense | The sensation felt in muscle when it is contracting; awareness of movement or activity in muscles or joints; sense of position or movement mediated in large part by the posterior columns and medial lemniscus. See: bathyesthesia. Synonym: deep sensibility, kinesthetic sense, mesoblastic sensibility, muscular sense, myoesthesis, myoesthesia. Origin: G. Mys, muscle, + aisthesis, sensation (05 Mar 2000) |

| sense | 1. <physiology> A faculty, possessed by animals, of perceiving external objects by means of impressions made upon certain organs (sensory or sense organs) of the body, or of perceiving changes in the condition of the body; as, the senses of sight, smell, hearing, taste, and touch. See Muscular sense, under Muscular, and Temperature sense. "Let fancy still my sense in Lethe steep." (Shak) "What surmounts the reach Of human sense I shall delineate." (Milton) "The traitor Sense recalls The soaring soul from rest." (Keble) 2. Perception by the sensory organs of the body; sensation; sensibility; feeling. "In a living creature, though never so great, the sense and the affects of any one part of the body instantly make a transcursion through the whole." (Bacon) 3. Perception through the intellect; apprehension; recognition; understanding; discernment; appreciation. "This Basilius, having the quick sense of a lover." (Sir P. Sidney) "High disdain from sense of injured merit." (Milton) 4. Sound perception and reasoning; correct judgment; good mental capacity; understanding; also, that which is sound, true, or reasonable; rational meaning. "He speaks sense." "He raves; his words are loose As heaps of sand, and scattering wide from sense." (Dryden) 5. That which is felt or is held as a sentiment, view, or opinion; judgment; notion; opinion.

Common sense, according to Sir W. Hamilton: "The complement of those cognitions or convictions which we receive from nature, which all men possess in common, and by which they test the truth of knowledge and the morality of actions." "The faculty of first principles." These two are the philosophical significations. "Such ordinary complement of intelligence, that,if a person be deficient therein, he is accounted mad or foolish." When the substantive is emphasized: "Native practical intelligence, natural prudence, mother wit, tact in behavior, acuteness in the observation of character, in contrast to habits of acquired learning or of speculation." Moral sense. See Moral, . The inner, or internal, sense, capacity of the mind to be aware of its own states; consciousness; reflection. "This source of ideas every man has wholly in himself, and though it be not sense, as having nothing to do with external objects, yet it is very like it, and might properly enough be called internal sense." . <anatomy> Sense capsule, one of the modified epithelial cells in or near which the fibres of the sensory nerves terminate. Synonym: Understanding, reason. Sense, Understanding, Reason. Some philosophers have given a technical signification to these terms, which may here be stated. Sense is the mind's acting in the direct cognition either of material objects or of its own mental states. In the first case it is called the outer, in the second the inner, sense. Understanding is the logical faculty, i. E, the power of apprehending under general conceptions, or the power of classifying, arranging, and making deductions. Reason is the power of apprehending those first or fundamental truths or principles which are the conditions of all real and scientific knowledge, and which control the mind in all its processes of investigation and deduction. These distinctions are given, not as established, but simply because they often occur in writers of the present day. Origin: L. Sensus, from sentire, sensum, to perceive, to feel, from the same root as E. Send; cf. OHG. Sin sense, mind, sinnan to go, to journey, G. Sinnen to meditate, to think: cf. F. Sens. For the change of meaning cf. See, See Send, and cf. Assent, Consent, Scent, Sentence, Sentient. Source: Websters Dictionary (01 Mar 1998) |
