joint, and the reduplicated apapilKSV, to join)  , the human upper limb from the shoulder to the wrist, and the fore limb of an animal . (See ANATOMY: Superficial and Artistic, and SKELETON: Appendicular.) The word is also used of any projecting limb, as of a crane, or balance, of a branch of a tree, and so, in a transferred sense, of the branch of a river or a nerve . Through the Fr. armes, from the Lat. arma, and so in English usually in the plural " arms," comes the use of the word for weapons of offence and defence, and in many expressions such as " men-at-arms," " assault-at-arms," and the like, and for the various branches, artillery, cavalry, infantry, of which an army is composed, the " arms of the service." " Arms " or " armorial bearings " are the heraldic devices displayed by knights in battle on the defensive armour or embroidered on the surcoat worn over the armour and hence called " coats of arms." These became hereditary and thus are borne by families, and similar insignia are used by nations, cities, episcopal sees and corporations generally .
