    • n incus In zoology and anatomy: One of the bones of the inner (middle) ear of a mammal: so named from its fancied resemblance to an anvil. It is the middle one of the chain of bones, or ossicula auditus, the other two being the malleus and the stapes. The human incus strikingly resembles a bicuspid tooth; it has a body and two processes, short and long, diverging from each other at nearly a right angle. The long process ends in a small globular head, the orbicular or lenticular process, tipped with cartilage and articulated with the head of the stapes. The body of the incus articulates with the malleus. Both articulations are movable. The lenticular process exists as a separate ossification in early life. In vertebrates below mammals the homologies of the incus are much disputed, and different bones or cartilages have been taken as its representative, especially those which constitute a proximal element of the hyoidean arch. See ear, and cut under tympanic.
