Editing Frontal bone (section)

== Structure ==
The frontal bone is made up of two main parts. These are the [[squamous part of the frontal bone|squamous part]], and the [[orbital part of frontal bone|orbital part]]. The squamous part marks the vertical, flat, and also the biggest part, and the main region of the [[forehead]]. The orbital part is the horizontal and second biggest region of the frontal bone. It enters into the formation of the roofs of the [[orbital cavity|orbital]] and [[nasal cavity|nasal cavities]]. Sometimes a third part is included as the '''nasal part of the frontal bone''', and sometimes this is included with the squamous part.  The nasal part is between the [[brow ridge]]s, and ends in a serrated '''nasal notch''' that articulates with the [[nasal bone]]s inferiorly, and with the [[lacrimal bone|lacrimal]] and [[Maxilla|maxilla bones]] laterally.<ref name="Gray's E-book 479">{{cite book |last1=Standring |first1=Susan |title=Gray's Anatomy E-Book: The Anatomical Basis of Clinical Practice |url=https://books.google.com/books?id=b7FVCgAAQBAJ&q=nasal+notch&pg=PA479 |publisher=Elsevier Health Sciences |language=en |date=7 August 2015|isbn=9780702068515 }}</ref>
