Adult Incus Anatomy
Component Description
Body (corpus incudis) somewhat cubical but compressed transversely anterior surface is a deeply concavo-convex facet facet articulates with the head of the malleus
Short Crus (crus breve, short process) somewhat conical in shape projects almost horizontally backward attached to the fossa incudis, in the lower and back part of the epitympanic recess
Long Crus (crus longum, long process) descends nearly vertically behind and parallel to the manubrium of the malleus bending medialward, ends in a rounded projection, the lenticular process lenticular process is tipped with cartilage, and articulates with the head of the stapes
