Palatine bones

Palatine bones ex situ & in situ. Superior and slightly anterior view. To better visualize palatine bones the rest of viscerocranium is dislocated separately from them.

Palatine bones ex situ & in situ. Inferior view. Palatine bones are the most dorsal bones of viscerocranium, acting like the bridge between processus pterygoideus & corpus ossis sphenoidalis from one side and maxilla from the other.

Palatine bones ex situ & in situ. Iso view. Two L-shaped palatine bones forms the dorsal part of nasal cavity

Markup for anterior aspect of palatine bones

Anterior aspect of palatine bones. Please note that in situ 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

Markup for posterior view of palatine bones

Posterior aspect of palatine bones.

The list of terms:

Crista ethmoidalis – Ethmoidal crest
Crista conchalis – Conchal crest
Processus pyramidalis – Pyramidal process

Bottom view of palatine bones.

The list of terms:

Facies palatina laminae horizontalis – Palatine surface of horizontal plate
Processus pyramidalis – Pyramidal process

Posterior lateral view of palatine bones

Markup for the postero-lateral view of palatine bones

Posterior & lateral aspect of palatine bones with some distance between bones.

The list of terms:
