Incus Berengario da Carpi in his "Commentaria super anatomia Mundini" (1521). Andreas Vesalius, in his "De humani corporis fabrica", was the first to compare the second element of the ossicles to an anvil, thereby giving it the name "incus". The final part of the long limb was once described as a "fourth ossicle" by Pieter Paaw in 1615. Incus The incus or anvil is a bone in the middle ear. The anvil-shaped small bone is one of three ossicles in the middle ear. The "incus" receives vibrations from the malleus, to which it is connected laterally, and transmits these to the
Ear decomposition ear. Additionally, in most cases the first ear in the sequence must be a cycle. An open ear decomposition or a proper ear decomposition is an ear decomposition in which the two endpoints of each ear after the first are distinct from each other. Ear decompositions may be used to characterize several important graph classes, and as part of efficient graph algorithms. They may also be generalized from graphs to matroids. Several important classes of graphs may be characterized as the graphs having certain types of ear decompositions. A graph is "k"-vertex-connected if the removal of any ("k" − 1)
