| mandibular fossa | socket-like depression directly anterior to external auditory meatus. Joint that allows the lower to move. |
| mastoid process | most posterior & inferior part of the temporal bone, triangular in shape |
| the widest measurment of the neck | between the mastoid process |
| zygomatic arches or zygomatic process of the temporal bone | long thin narrow arch-like ribbon of bone. Arises directly above ear passage, extends anteriorly, and bulges out. |
| the widest part of the face is measured between | the zygomatic arches |
| The frontal bone is located | most anterior and superior bone of the cranium. Forms the forehead and anterior part of the crown, also forms the upper part of the temple |
| frontal bone is separated from the parietal bones by the | coronal suture |
| frontal bone is separated from the temporal bones by the | squamosal suture |
| frontal eminece is | where dirction changes on frontal bone. 2 round bumps in the hairline |
| superciliary arches | eyebrow arches, 2 comma-shaped arch-like eminences, lower part of the forehead, just above the medial ends of the eyebrows |
| supraorbital margin | 2 ridges just above the eye sockets, curves and forms the lateral boundary of the eye sockets |
| glabella | small, smooth elevation between superciliary arches, nasal bone starts right below |
| lines of the temple | 2 vertical ridges on each side of the frontal bone, starts above the lateral rim of the eye socket, goes up vertically and arches medially, ends at level of frontal emineces. divides forehead from lateral part of frontal bone |
| what is the degree of the angle of the frontal bone | 110 |
| central plane of the frontal bone | located in the front of the forehead between the upper arch of eyebrows, is the flattest part of the skull. extends vertically and horizontally |
| medial plane of the frontal bone | narrow area just above the nose midline, imaginary line rising vertically above a point slightly lateral to the ends of the eyebrows |
| lateral plane on the frontal bone | wider, extends from line to line of temple-curve inward |
| the nasal bones are located | directly inferior and obliquely anterior to glabella. nasal bones fuse and form superior part of nose. 2 frontal planes, 2 lateral planes-dome of the nose is where glasses sit |
| nasal septum | bone that divides internally, perpendicular with midline upper plate of ethmoid bone, lower part is vomer |
| cartalage attaches to ____ and ____ in the nose | plate of ethmoid bone and vomer |
| zygomatic (zygomae) are the _____ and located____ | check bones, inferior and lateral to the orbital cavities |
| prominence of the cheek | 2 crests of curbature of zygomatic bones, occurs where the bone changes direction. Slightly inferior and lateral to the outer corner of the eye, refurred to as the warm area of the face |
| distance between the prominences of the checks are the | widest part of the anterior plane of the face |
| maxillary (maxillar) is located | inferior to the nasal cavity and lateral to nasal cavity and nasal bones, forms the boundary of the nasal cavity. connects to the nasal, frontal & zygomatic bones |
| the central bone of the face is and forms the upper jaw | the maxillary |
| maxilla sinus | hollow cavity inside the maxillary bone that warms incoming air and acts as a vocal resonator |
| nasal spine | small sharp spur of bone that projects where 2 bones meet at midline, directly inferior to the nasal cavity |
