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 elastic cartilage with a complicated relief on its inner surface and a fairly smooth configuration on its posterior surface. A tubercle, known as Darwin's tubercle, is sometimes present, lying in the descending part of the helix and corresponding to the ear-tip of mammals. The earlobe consists of areola and adipose tissue. The symmetrical arrangement of the two ears allows for the localisation of sound. The brain accomplishes this by comparing arrival-times and intensities from each ear, in circuits located in the superior olivary complex and the trapezoid bodies which are connected via pathways to both ears. The middle ear lies
