Palatine bones ex situ & in situ.
Superior and slightly anterior view. Superior and slightly anterior view. To better visualize palatine bones, the rest of viscerocranium is displaced separately.
The palatine bones ex situ & in situ. Inferior view.
Palatine bones are the most dorsal bones of the viscerocranium, acting as the bridge between processus pterygoideus & corpus ossis sphenoidalis from one side and maxilla from the other.
The palatine bones ex situ & in situ. Iso view.
Two L-shaped palatine bones form the dorsal part of the nasal cavity.
The anterior aspect of palatine bones.
Please note that both bones are in contact with each other, and the distance between two lamina horizontalis practically doesn't exist.
The list of terms:Lamina perpendicularis – Perpendicular plate Lamina horizontalis – Horizontal plate Processus orbitalis – Orbital process Incisura sphenopalatina – Sphenopalatine notch Processus sphenoidalis – Sphenoidal process
The posterior aspect of palatine bones.
The list of terms:Crista ethmoidalis – Ethmoidal crest Crista conchalis – Conchal crest Processus pyramidalis – Pyramidal process
The bottom view of palatine bones.
The list of terms:Facies palatina laminae horizontalis – Palatine surface of horizontal plate Processus pyramidalis – Pyramidal process Processus sphenoidalis – Sphenoidal process Spina nasalis posterior – Posterior nasal spine Sulcus palatinus major – Greater palatine sulcus (pterygopalatine sulcus)
Posterior & lateral aspect of palatine bones with some distance between bones.
The list of terms:Facies nasalis laminae perpendicularis – Nasal surface of perpendicular plate Facies maxillaris laminae perpendicularis – Maxillary surface of perpendicular plate Processus orbitalis – Orbital process Processus pyramidalis – Pyramidal process Processus sphenoidalis – Sphenoidal process Sulcus palatinus major – Greater palatine sulcus Crista nasalis – Nasal crest
The lateral aspect of right palatine bone.
Note that posterior & inferior portion of the maxillar surface directly articulate with maxilla and anterior portion of that surface cover the maxillary sinus.
The list of terms:Facies maxillaris laminae perpendicularis – MAxillary surface of perpendicular plate Sulcus palatinus major – Greater palatine sulcus Incisura sphenopalatina – Sphenopalatine notch
