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 Ear The ear is the organ of hearing and, in mammals, balance. In mammals, the ear is usually described as having three parts—the outer ear, middle ear and the inner ear.

The inner ear sits in the bony labyrinth, and contains structures which are key to several senses: the semicircular canals, which enable
