In anatomy and zoology, the outer one of the two bones of the forearm, or corresponding part of the fore leg; the bone on the thumb side of the forearm, extending from the humerus to the carpus, and bearing upon its distal end the manus or hand: so called from its revolving, somewhat like a spoke, about the ulna, as in man and other mammals whose fore limb exhibits the motions called pronation and supination. noun

In ichthyology, a bone of the pectoral arch, wrongly identified by some naturalists with the radius of higher vertebrates. The one so called by Cuvier is the hypercoracoid, and that of Owen is the hypocoracoid. noun

In echinoderms, one of the five radial pieces of the dentary apparatus of a sea-urchin, being an arched rod-like piece articulated at its base with the inner extremity of each rotula, running more or less nearly parallel with the rotula, and ending in a free bifurcated extremity. Also called the compass of the lantern of Aristotle (which see, under lantern). See also cut B under lantern. noun

The long bone in the forearm, on the side of the thumb.

The lighter bone (or fused portion of bone) in the forelimb of an animal.

One of the major veins of the insect wing, between the subcosta and the media; the vein running along the costal edge of the discal cell.

A line segment between any point of a circle or sphere and its center.

The length of this line segment.

Anything resembling a radius, such as the spoke of a wheel, the movable arm of a sextant, or one of the radiating lines of a spider's web.

Half the diameter of a circle Urban Dictionary

The strong unexplainable pull of one's "pick-up abilities" on a girl of choice that is in said radius. Urban Dictionary

The distance of your radius that you will acknowledge the people you know and greet them. Greeting radii almost always depend on person. Usually, your greeting radius varies based on how much you like the person. Someone you are close friends with, will probably have a greeting radius of over 50ft. For people you don't like, it would probably be something like 10ft if it's crowded where you are. Urban Dictionary

The distance a man is able to comfortably travel (from his bed) without pants; the average radius being just the distance to the shower. It is theorized that a man's underpants radius is inversely proportional to his confidence; that is, the farther a man travels from his bed in just his underwear, the less he believes in himself. Urban Dictionary

The length that one’s balls hang down below their taint. This measurement provides the maximum distance ones scrotum could swing in any given direction. Measured to lowest hanging ball. Urban Dictionary

Radial distance (R.O.S.) from a source of something that smells unpleasant (B.O., poorly wiped ass, out of control vaginosis, smelly feet, etc.) Urban Dictionary

The radius that yo rizz reaches. Urban Dictionary

A distance correlated with the area of a city in which a person would want to walk during the winter or in the cold. In northern cities, a summer radius is usually much larger than a winter radius, due to the warmer weather and better walking conditions. Urban Dictionary
