| restriction length polymorphism | Fragment length polymorphism, the existence of allelic forms recognizable by the length of fragments that result when the nucleotide chain is treated by a specific restriction enzyme that cleaves wherever a particular sequence of nucleotides occurs. A mutation in this sequence changes cleaving and hence the number of fragments. (05 Mar 2000) |

| greatest length | Measurement from the cranial to caudal end of the embryo prior to folding. (05 Mar 2000) |
| crown-heel length | Length of an outstretched embryo or foetus from skull vertex to heel. See: Streeter's developmental horizon(s). (05 Mar 2000) |
| crown-rump length | In utero measurement corresponding to the sitting height (crown to rump) of the foetus. Length is considered a more accurate criterion of the age of the foetus than is the weight. The average crown-rump length of the foetus at term is 36 cm. (12 Dec 1998) |
| height-length index | The relation of the height to the length of the skull: (height × 100)/length. Synonym: height-length index, length-height index, transversovertical index. (05 Mar 2000) |
| spinal length | A measurement from the distal surface of the embryo where the plane passes through the developing eye (this is the cranial limit of the spinal cord) down to the rump. (05 Mar 2000) |
| unit of length | Metric system and SI: meter, CGS system: centimeter, variable in the English system: inch for short distances, foot for moderate distances and for elevation, mile for long distances. (05 Mar 2000) |
| leg length inequality | A condition in which one of a pair of legs fails to grow as long as the other. (12 Dec 1998) |
| length | 1. The longest, or longer, dimension of any object, in distinction from breadth or width; extent of anything from end to end; the longest line which can be drawn through a body, parallel to its sides; as, the length of a church, or of a ship; the length of a rope or line. 2. A portion of space or of time considered as measured by its length; often in the plural. "Large lengths of seas and shores." (Shak) "The future but a length behind the past." (Dryden) 3. The quality or state of being long, in space or time; extent; duration; as, some sea birds are remarkable for the length of their wings; he was tired by the length of the sermon, and the length of his walk. 4. A single piece or subdivision of a series, or of a number of long pieces which may be connected together; as, a length of pipe; a length of fence. 5. Detail or amplification; unfolding; continuance as, to pursue a subject to a great length. "May Heaven, great monarch, still augment your bliss. With length of days and every day like this." (Dryden) 6. Distance. "He had marched to the length of Exeter." (Clarendon) at length. At or in the full extent; without abbreviation; as, let the name be inserted at length. At the end or conclusion; after a long period. See Syn. Of At last, under Last. At arm's length. See Arm. Origin: OE. Lengthe, AS. Leng, fr. Land, long, long; akin to D. Lengte, Dan. Laengde, Sw. Langd, Icel. Lengd. See Long. Source: Websters Dictionary (01 Mar 1998) |
| length-breadth index | The ratio of the maximal breadth to the maximal length of the head, obtained by the formula: (breadth × 100)/length. Synonym: length-breadth index. (05 Mar 2000) |
| length-height index | The relation of the height to the length of the skull: (height × 100)/length. Synonym: height-length index, length-height index, transversovertical index. (05 Mar 2000) |

| Berger's focal glomerulonephritis | Glomerulonephritis affecting a small proportion of renal glomeruli which commonly presents with haematuria and may be associated with acute upper respiratory infection in young males, not usually due to streptococci; associated with IgA deposits in the glomerular mesangium and may also be associated with systemic disease, as in Henoch-Schonlein purpura. Synonym: Berger's disease, Berger's focal glomerulonephritis, focal nephritis, IgA nephropathy. (05 Mar 2000) |

| focal length |
The distance from a camera lens's focal point to its CCD imaging chips with the lens focus set to infinity. Wide angle views use short focal length; narrow field of view (telephoto) use longer focal lengths. Zoom lenses have a variable focal length.

| focal length |
The distance from a point where an image is formed (the focal point) to a point in or near the lens or lens system. [In the sketch at right, this is labeled FL.] Focal Point - That point where the light rays coming from a distant object converge after passing through a lens, coming to a focus and forming an image. [The point FP in this sketch.]

| focal length |
The distance between the film plane and the focal point (optical centre of the lens) when the lens is focused at infinity. The focal length of the lens is marked in millimetres on the lens mount. The principal focal point is the position of best focus for infinity. There are two principal focal points, if a lens is turned around a second focus is obtained. 'Reversed' lenses are often used in close-up Macrophotography because using a lens reversed allows a closer focusing distance. ...
