The malleus, or hammer, is the largest of the three ossicles. The club-shaped superior part is called the head. On its posterior surface, the head articulates with the incus. The neck (collum) separates the head from the handle (manubrium). A small lateral process projects from the superolateral aspect of the manubrium and is readily visible as a bulge in the tympanic membrane.
