A leg is a weight bearing and locomotive structure, usually having a columnar shape. During locomotion, legs function as "extensible struts"[1] - 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.

Terminology [link]
Many taxa are characterized by the number of legs:
- Tetrapod
- Arthropoda: 4, 6 (Insecta), 8, 12, or 14
- Some arthropods have more than a dozen legs; a few species possess over 100. Despite what their names might suggest,
- Centipedes may have less than 20 or more than 300 legs.
- Millipedes have fewer than 1,000 legs, but up to 750.
- Some arthropods have more than a dozen legs; a few species possess over 100. Despite what their names might suggest,
Tetrapod legs [link]
In tetrapod anatomy, leg is used to refer to the entire limb. In human medicine its precise definition refers[2][3][4] only to the segment between the knee and the ankle. This segment is also called the shank,[5][6] and the front (anterior) of the segment is called the shin or pretibia.
In bipedal tetrapods, the two lower limbs are referred to as the "legs" and the two upper limbs as "arms" or "wings" as the case may be.

Legs (novel)

Plot summary
The book chronicles the life of the gangster Jack 'Legs' Diamond. It is told from the perspective of Jack's lawyer, Marcus Gormen.

Gremlins
Gremlins is a 1984 American comedy horror film directed by Joe Dante and released by Warner Bros. The film is about a young man who receives a strange creature called a mogwai as a pet, which then spawns other creatures who transform into small, destructive, evil monsters. This story was continued with a sequel, Gremlins 2: The New Batch, released in 1990. Unlike the lighter sequel, Gremlins opts for more black comedy, balanced against a Christmastime setting. Both films were the center of large merchandising campaigns.
Steven Spielberg was the film's executive producer and the screenplay was written by Chris Columbus. The film stars Zach Galligan and Phoebe Cates, with Howie Mandel providing the voice of Gizmo, the main mogwai character. Gremlins was a commercial success and received positive reviews from critics. However, the film was also heavily criticized for some of its more violent sequences. In response to this and to similar complaints about Indiana Jones and the Temple of Doom, Spielberg suggested that the Motion Picture Association of America (MPAA) alter its rating system, which it did within two months of the film's release.

Fictional character biography
Mikron O'Jeneus
A bald dwarf who flies around on a jet pack, Gizmo is a genius inventor who can turn seemingly innocuous objects like vacuum cleaners into dangerous weapons. Gizmo created a corporation which supplied technology to various people, including criminals. Hoping to increase his wealth, Gizmo joined the Fearsome Five through an ad placed in the Underworld Star, a criminal underground newsletter, by the psychopathic criminal Doctor Light.
After a number of unsuccessful conflicts with the Teen Titans, (and Superman in Adventures of Superman #430) Gizmo went straight for a while, and took a job at S.T.A.R. Labs, until his former Fearsome Five teammate Psimon, after having been seemingly killed by his teammates, resurfaced looking for revenge, and shrank Gizmo to microscopic size. Years later, Gizmo found a way to revert to his normal size, and took up a life of crime once again, partnering with his former teammate, Mammoth.
