The distal end of the pterygoid contacts the squamosal dorsally and the quadrate medially. |
|
Jaw closing is the result of the action of the jaw elevators, i.e., masseter, temporalis and medial pterygoid muscles. |
|
The plates are separated below by an angular cleft, the pterygoid fissure, the margins of which are rough and articulate with the pyramidal process of the palatine. |
|
Posteriorly, the pterygoid thins to less than 1 mm in thickness. |
|
The posterior aspect of the lateral pterygoid plate may be joined to the angular spine of the greater wing by a pterygopetrosal ligament that may calcify. |
|
It curves laterally at its distal end into a hook-like process, the pterygoid hamulus, around which the tendon of the Tensor veli palatini glides. |
|
It may be formed of two superimposed layers and it may be more or less fused with the lateral pterygoid or send a fasciculus to the condylar process. |
|
The position usually occupied by the maxillary has been taken by the pterygoid bone. |
|
Characteristic of plethodontids, the new species has nasolabial grooves but no lungs or pterygoid bone. |
|
In mammals a secondary palate is formed by processes of the maxillary bones and the palatines, with the pterygoid bones reduced in importance. |
|
In this study, zygoma, pterygoid and regular platform implants were used. |
|
Computed tomography showed extensive pneumatization of the sphenoid sinus into the pterygoid process. |
|
The pterygoid and peribullar sinuses that form the cavity tend to be more developed in shallow water and riverine species than in pelagic Mysticeti. |
