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:

    I keep thinking that what I need
    to do is buy my leg back.
    Surely it is for sale somewhere,
    poor broken tool, poor ornament.
    It might be in a store somewhere beside a lady’s scarf.
    Anne Sexton (1928–1974)

    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)

    Eye of newt and toe of frog,
    Wool of bat and tongue of dog,
    Adder’s fork and blind-worm’s sting,
    Lizard’s leg and owlet’s wing,
    For a charm of powerful trouble,
    Like a hell-broth boil and bubble.
    William Shakespeare (1564–1616)
