| pterygoid process | A long process extending downward from the junction of the body and great wing of the sphenoid bone on either side; it is formed of two plates (lateral and medial), united anteriorly but separated below to form the pterygoid notch; the pterygoid fossa is formed by the divergence of these two plates posteriorly. Synonym: processus pterygoideus, os pterygoideum. (05 Mar 2000) |

| pyramidal process | The portion of the palatine bone passing lateral and posterior from the angle formed by the vertical and horizontal plates. Synonym: processus pyramidalis. (05 Mar 2000) |
| sheath of styloid process | A crest of bone (edge of the tympanic portion of the temporal bone) running from the front and medial side of the mastoid process to the spine of the sphenoid; it splits to ensheath the base of the styloid process. Synonym: vagina processus styloidei, vaginal process. (05 Mar 2000) |
| sheath process of sphenoid bone | A thin lamina of bone that extends medially under the body of the sphenoid bone from the medial lamina of the pterygoid process; it articulates with the vomer and the palatine bone.
