The incus (Latin an anvil) is located between the 
malleus and the stapes and articulates with them. It has a body and two 
limbs. Its large body lies in the epitympanic recess, where it 
articulates with the head of the malleus. The long limb lies parallel to
 the handle of the malleus, and its interior end articulates with the 
stapes by way of the lenticular process, a medially directed projection.
 The short limb is connected by a ligament to the posterior wall of the 
tympanic cavity.
