Replacement bone that is bilaterally paired and articulates with the neurocranium dorsally and the opercle posteriorly.[TAO]
relationship loss: overlaps preopercle vertical limb-hyomandibula joint (TAO:0005278)[TAO], relationship loss: overlaps hyomandibula-metapterygoid joint (TAO:0001979)[TAO], relationship loss: overlaps hyomandibula-opercle joint (TAO:0005265)[TAO], relationship loss: overlaps hyomandibular-otic region joint (TAO:0001947)[TAO], relationship loss: overlaps quadrate-hyomandibula joint (TAO:0001801)[TAO]
This structure (the hyomandibular), on ontogenic grounds alone, can be considered homologous with the amphibian and reptilian columella and the mammalian stapes.[well established][VHOG]
In most teleosts, there is a symplectic, and the hyomandibula articulates with it anteroventrally.
