Leg

A leg is a weight bearing and locomotive structure, usually having a columnar shape. During locomotion, legs function as "extensible struts" - the combination of movements at all joints can be modeled as a single, linear element capable of changing length and rotating about an omnidirectional "hip" joint.

As an anatomical animal structure it is used for locomotion. The distal end is often modified to distribute force (such as a foot). Most animals have an even number of legs.

As a component of furniture it is used for the economy of materials needed to provide the support for the useful surface, the table top or chair seat.

Famous quotes containing the word leg:

    “Which is more important to you, your field or your children?” the department head asked. She replied, “That’s like asking me if I could walk better if you amputated my right leg or my left leg.”
    —Anonymous Parent. As quoted in Women and the Work Family Dilemma, by Deborah J. Swiss and Judith P. Walker, ch. 2 (1993)

    Here’s a wing [laughs]. What do you like, the leg or the wing, Henry, or do you still go for the old hearts and lungs?
    Nicholas Pileggi, U.S. screenwriter, and Martin Scorsese. Tommy DeVito (Joe Pesci)

    Entrance and exit wounds are silvered clean,
    The track aches only when the rain reminds.
    The one-legged man forgets his leg of wood.
    The one-armed man his jointed wooden arm.
    The blinded man sees with his ears and hands
    As much or more than once with both his eyes.
    Robert Graves (1895–1985)
