Document Summary

Baker | fors 3331 | spring 2017 | lecture 8 | page 1. Small, thin, fragile, rectangular bones that are part of the medial walls of the orbits anterior to the ethmoid. They articulate with the frontals, maxillae, ethmoid, and inferior nasal conchae. Form via intramembranous ossification from a single center. Small, thin, rectangular bones below the glabellar region. Non-articular, free inferior ends form the top of the nasal aperture. They articulate superiorly with the frontal; laterally with maxillae; and posteriorly with the ethmoid. They form via intramembranous ossification from a single center. Articulate with the frontal, sphenoid, temporal and maxilla. Form via intramembranous ossification from 3 centers and fuse during fetal development. Frontal process - extends vertically: articulates with the frontal. Temporal process - extends posteriorly: articulates with the zygomatic process of he temporal to form the zygomatic arch. Maxillary process - extends medially: articulates with the maxilla to form the infraorbital margin.
