The incudostapedial joint is a small, synovial ball-and-socket joint between the incus (anvil) and the stapes (stirrup). The joint's function is to transfer vibrations between the two ossicles. The incudostapedial joint lies between the long leg of the incus (long crus, or crus longum incudis) and the head of the stapes (caput stapedis).[1] The long leg moves with the rest of the incus, and a small knob, the lenticular process, articulates with the head of the stapes.[citation needed]
