The incus (plural: incudes) is the middle of the three ossicles articulating with the head of the malleus anteromedially, forming the incudomalleolar joint, and the stapes inferomedially, forming the incudostapedial joint.

Gross anatomy
Four parts of the incus are named:
-
body
contiguous with the short and long processes
articulates with the head of the malleus
attaches the superior ligament of the incus (to the roof of the middle ear cavity)
-
long process (or crus)
contiguous with the body and lentiform process
-
lentiform process (or lentiform nodule)
contiguous with the long process
articulates with the head of the stapes
-
short process (or crus)
contiguous with the body
attaches the posterior ligament of the incus
History and etymology
Incus is the Latin word meaning anvil 3.
Related pathology
The long crus is the most frequently eroded or resorbed part of the ossicles.
