The incus (pl.: incudes) or anvil in the
Latin
: incus).
Structure
The incus is the second of three
posterior ligament of the incus. The long crus articulates with the stapes
at the lenticular process.
The
superior ligament of the incus attaches at the body of the incus to the roof of the tympanic cavity
.
Function
Vibrations in the
tympanic membrane. The malleus, resting on the membrane, conveys vibrations to the incus. This in turn conveys vibrations to the stapes.[2]
History
"Incus" means "anvil" in Latin. Several sources attribute the discovery of the incus to the anatomist and philosopher
De humani corporis fabrica,[6] was the first to compare the second element of the ossicles to an anvil, thereby giving it the name incus.[7] The final part of the long limb was once described as a "fourth ossicle" by Pieter Paaw in 1615.[8]
