Dorsally it articulates with the otic capsule at the hyomandibular fossa, ventrally with the quadrate and symplectic. In most Teleostei it has a foramen for the hyomandibular branch of the facial nerve (VII). hyomandibula - stapes relationship loss: overlaps hyomandibular-otic region joint (TAO:0001947)[TAO] relationship loss: overlaps preopercle vertical limb-hyomandibula joint (TAO:0005278)[TAO] epihyal relationship loss: overlaps hyomandibula-opercle joint (TAO:0005265)[TAO] relationship loss: overlaps quadrate-hyomandibula joint (TAO:0001801)[TAO]
