- n. A thunderhead.
Century Dictionary and Cyclopedia
- n. 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.

Examples
“Connected with the malleus is another small bone, called the incus, or anvil, which is connected with another, called the stapes, or stirrup, from its shape.”
Popular Lectures on Zoonomia Or The Laws of Animal Life, in Health and Disease
“The malleus is connected through a tiny joint to the incus, which is attached to the stapes, both of which vibrate in their turn as result of the vibrations of the bone preceding them.”
“The malleus and the incus are the remnants of bones that in our reptilian ancestors were to be found in the jaw, as I explained earlier.”
“The peripheral system includes the external ear (auricle and ear canal), the tympanic membrane, or eardrum, the middle ear (three small and connected bones: malleus, incus, and stapes), the oval window boundary, and the inner ear (vestibular system and cochlea).”
““The malleus, the incus, and the stapes,” I answered automatically.”
“Your long crus of incus chillax maxilla, buoyant in vignette.”
“The surgery needed for the Envoy device, in particular, has raised eyebrows among some doctors because it involves removing a portion of the incus, a small bone in the middle ear.”
“If the implant is removed, the incus will need to be reconstructed surgically and the patient may lose some hearing.”
“Patrick Spearman, co-chief executive of Envoy, says one patient who had the device removed had his incus successfully reconstructed using bone cement, with hearing slightly diminished compared with prior to the implant.”
“So malleus and the incus, or the hammer and the anvil, are actually the quadrate and the articular that used to be in the jaw joint, and now they are hooked up to the stapes here of the ear.”
