| proboscidifera | 1. <zoology> An extensive division of pectinibranchiate gastropods, including those that have a long retractile proboscis, with the mouth at the end, as the cones, whelks, tritons, and cowries. 2. <zoology> A subdivision of the taenioglossate gastropods, including the fig-shells (Pyrula), the helmet shells (Cassis), the tritons, and allied genera. Origin: NL. See Proboscis, and -ferous. Source: Websters Dictionary (01 Mar 1998) |

| proboscis | 1. <zoology> A hollow organ or tube attached to the head, or connected with the mouth, of various animals, and generally used in taking food or drink; a snout; a trunk. The proboscis of an elephant is a flexible muscular elongation of the nose. The proboscis of insects is usually a chitinous tube formed by the modified maxillae, or by the labium. 2. <zoology> By extension, applied to various tubelike mouth organs of the lower animals that can be everted or protruded. The proboscis of annelids and of mollusks is usually a portion of the pharynx that can be everted or protruded. That of nemerteans is a special long internal organ, not connected with the mouth, and not used in feeding, but capable of being protruded from a pore in the head. 3. The nose. Proboscis monkey. Origin: L. Fr. Gr.; before + to feed, graze. (19 Mar 1998) |
| probract | Small, leaf-like structure at the base of an inflorescence in members of the cucumber family (Curcurbitaceae), usually arising opposite a tendril. (09 Oct 1997) |
| Probstymayria vivipara | A nematode (family Atractidae) closely related to the true pinworms (family Oxyuridae) and still commonly considered the horse pinworm; it is distributed worldwide and is found often in tremendous numbers, because of internal autoreinfection, in the colon of horses and other equids. (05 Mar 2000) |
| probucol | <chemical> A drug used in the treatment of hypercholesteraemia. It lowers total plasma cholesterol concentrations, mainly by reducing low-density lipoprotein-cholesterol and high-density lipoprotein-cholesterol concentrations. It has little effect on serum-triglyceride or very-low-density lipoprotein-cholesterol concentrations. Pharmacological action: anticholesteraemic agents. Chemical name: Phenol, 4,4'-((1-methylethylidene)bis(thio))bis(2,6-bis(1,1-dimethylethyl)- (12 Dec 1998) |

| probability density function |
(Or density function; also called frequency function.) The statistical function that shows how the density of possible observations in a population is distributed. It is the derivative f(x) of the distribution function F(x) of a random variable, if F(x) is differentiable. Geometrically, f(x) is the ordinate of a curve such that f(x)dx yields the probability that the random variable will assume some value within the range dx of x. ...

| probability distribution |
The mathematical description of a random variable in terms of its admissible values and the probability associated, in an appropriate sense, with each value. The probability distribution of a continuous variate is defined by stating the mathematical equation of the distribution function F(x) or the probability density function f(x) (if it exists) together with the range over which the equation holds. ...
