In anatomy, an arm'" is one of the upper limbs of an animal. The term "arm" can also be used for analogous structures, such as one of the paired upper limbs of a four-legged animal, or the arms of cephalopods. In the lexicon of human anatomy, the term "arm" refers specifically to the segment between the shoulder and the elbow. The segment between the elbow and wrist is the forearm. However, in colloquial speech the term "arm" often refers to the entire upper limb from shoulder to wrist. In primates the arms are richly adapted for both climbing and for more skilled, manipulative tasks. The ball and socket shoulder joint allows for movement of the arms in a wide circular plane, while the presence of two forearm bones which can rotate around | A leg is a limb on an living thing'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 (see foot). In bipedal vertebrate animals, the two lower limbs are usually referred to as the 'legs' and the two upper limbs as the 'arms' or 'wings' as the case may be. "Leg" is also a military term used to describe a service man (or woman) without airborne qualification. (no jump wings) Legs typically come in even-numbered quantities. Many taxonomic groups are characterized by the number of legs its members possess. |
