The foot is an anatomical Anatomy is a branch of biology and medicine that is the consideration of the structure of living things. It is a general term that includes human anatomy, animal anatomy (zootomy) and plant anatomy (phytotomy). In some of its facets anatomy is closely related to embryology, comparative anatomy and comparative embryology, through common roots in structure found in many vertebrates Vertebrates are members of the subphylum Vertebrata, chordates with backbones or spinal columns. About 58,000 species of vertebrates have been described. Vertebrata is the largest subphylum of chordates, and contains many familiar groups of large land animals. Vertebrates comprise cyclostomes, bony fish, sharks and rays, amphibians, reptiles,. It is the terminal portion of a limb which bears weight and allows locomotion Animal locomotion, which is the act of self-propulsion by an animal, has many manifestations, including running, jumping and flying. Animals move for a variety of reasons, such as to find food, a mate, or a suitable microhabitat, and to escape predators. For many animals the ability to move is essential to survival and, as a result, selective. In many animals with feet, the foot is a separate organ at the terminal part of the leg A leg is a limb on a organism's body that supports the rest of the animal above the ground between the ankle and the hip and is used for locomotion. The end of the leg farthest from the animal's body is often either modified or attached to another structure that is modified to disperse the animal's weight on the ground . In bipedal vertebrate made up of one or more segments or bones, generally including claws or nails.
