LRA 222: Course Examination
1.Smooth, raised triangular area between and slightly superior to the
eye- brows, above the bridge of the nose: Glabella
2.Junction of the frontal bone and nasal bone: Nasion
3.Lower posterior angle on the jaw or mandibles: Goinion
4.External portion of the ear: auricle
5.Midpoint of the triangle area of the chin: Mental point
6.The ridge or arch of the bone that extends across forehead: Superciliary
Arch
7.The slight groove or depression: Supraorbital groove (SOG)
8.The line thatconnects the glabella to EAM: GML
9.Lateral junction of the eyelids: Outer Canthus
10.The midline point at the junction of the upper lip and nasal septum:
Acan- thion
11.where the eyelids meet near the nose: inner canthus
12.Inferior rim of the bony orbit of the eye: Infraorbital Margin (IOML)
13.The lines that connects from EAM to chin: MML
14.A line located between the outer canthus and EAM: OML
15.The line that runs threw pupils: IPL
16.The glabella is considered superior to nasion: TRUE
17.Which of the following lines is placed perpendicular to the image
receptor plan for the AP axial projection if they can't put there chin down:
OML
18.What projection of the skull requires the central ray to exit the glabella:
PA skull
19.What projection of the skull requires the midsagittal to be parallel to
the IR and the interpupillary line perpendicular to IR: Lateral Projection
20.What is the difference, in degrees between the orbitmeatal and
infraorbit- omeatal line: 7-8 degrees
21.A radiograph of a lateral projection of the cranium reveals that the
orbital roofs (plates) are not superimposed—one is slightly superior to the
other. Which of the following positioning errors led to this radiographic
outcome?-
: Tilt

, 22.A radio radiographic of a posterior anterior (PA) axial projection
(Caldwell method) of the cranium reveals that the petrous ridges are located
at the level of the lower on third of the orbits. The technologist performed
this projection with the CR angled 15 degrees caudal to the orbitimeatal line
(OML). How much positioning be altered if a repeat exposure is performed?:
Nothing this position is CORRECT
23.Where is the CR centered for a lateral projection of the facial bones?:
Zy- goma
