From Brickipedia, the LEGO Wiki.

A minifigure Leg is a rounded part rectangle which serves as a LEGO minifigure's leg. The foot is as big as a 1x1 plate. Above the leg is thinner and becomes round at the top.

There is a different piece for the right and left legs, witch are connected to the hip. They are also available in different colours.
