cranium-judy
| Question | Answer |
|---|---|
| What baseline is important when doing a PA skull? | orbitomeatal |
| the outwe border of the eye, where upper and lower eyelids meet, is the | midlateral orbital margin |
| name a structuyre that will not be demonstrated on a lateal skull picture | occpital condyle |
| the CR for a PA of the cranium passes thru the nasion at an angle of | 15 caudad |
| for a reverse towne position, the CR enters the skull 1.5 inches below the | External occpital protuberance |
| the cristagalli is well demonstratged in what projection? | PA |
| the ap axial (extraoral) projection of the mandible is preformed to demonstrate the | body |
| the best projection for facial bones on an injured patient who should not be turned prone is the | AP axial waters |
| the PA axial projection of the mandible best visualizes the | mandibular rami |
| in a full basal projection of the skull, the infraorbital line should be | as nearly parallel to the fild as possible |
| T/F the partoid is the largest salavary gland | T |
| T//Fthe antrum of highmore is located within the maxillary sinus | T |
| T/F the vomer located on the floor of the cranium | F |
| the cranial structures are diarthorodial | F |
| name a bone that contains a paranasal sinus | sphenoid |
| located between the upper and adjacent borders of the two parieltal boned is a suture called the : | saggital |
| what view will deomonstrate the petrous pyramids, dorsum sellae, and posterior clinoid process? | AP axial |
| T/F the caldwell projection demonstrated the frontal sinuses | t |
| t/f the inion is located within the occpital | t |
| t/f the crista galli is located within the temporal | f |
| t/f the mastoid cells are found within the temporal | t |
| t/f the stenver's projection demonstrates the petrous ridges | t |
| t/f the waters projection demonstrates the the maxillary sinus | t |
| t/f the laws projection demonstrtes the optic foramina | f |
| the most commoly used position for demonstration of the maxillary dinuses is the | waters |
| an excellent position to demonstrate facial bones is the | WATERS |
| t/f the floor of the skill is made up of 6 bones | f |
| t/f the vomer forms the lower part of the nasal septum | t |
| t/f the parielta forms the greater protion of the sides and roof of the cranium | t |
| t/f the pterygoids are found on the inferior surface of the sphnoid | t |
| t/f the parietal bone articualtes with the ethmoid | f |
| t/f the anterior-superior portion of the temporal bone is squamous | t |
| t/f the condyle of the mandible articualtes with the temporal | t |
| in radiography of the nasal bones, the alteral projection will have the interpupillary line | perpendicular to the film |
| in order to posiion a patient properly for a reverse view of th eoptic foramen, you should adjust the head so that its medial sadittal polane will form with the plane fo the film an angle of | 53 degrees with the acanthiomeatal line perpendicualr |
| the acanthiomeatal line is perpendicualr to the film plane in a proper | rhese position |
| in a routine waters view for sinuses, the head is resting on the menti of the chin and the CR is | perpendicualr to the film at the acantion |
| a properly positoned caldwell projection of the skull will demonstrate what three structures | petrous pyramids, frontal sinuses, and anterior ethmoid cells |
| the caldwell projection of the skull requires that the central ray be angled | 15-20 degrees caudad |
| the patient is prone, the msp forms an angle of 45 degrees with the table top and the infraorbitalmeatal line is perpendicualr to the table top. This is called a | stenver's projection |
| waht topographical landmark forresponds to the floor of the cranium? | superorbital groove |
| the articulations of the mandible are an example of which type of joint? | diarthrodial |
| what is the part of the skull that surrounds and protects the brain? | cranium |
| where is the exact location of the optic foramen? | apex of the orbit |
| name three anatomical structures that would be found in the petrous portion of the temporal bone | ossicle, cochlea, and tympanic cavity |
| what is the name of the point where the two pariteals articulate with the occpital bone | lambda |
| what is the name of the membrane that seperates the EAM from the middle ear | tympanic membrane |
| what is the posterior portion of the sella turcica called | dorsum sellae |
| name two facial bones that are paried | zygomatic and maxilla |
| what term describes describes the horizontal protion of the mandible | body |
| name the position that demonstrates the optic foramen | rhese |
| wht gland would be demonstrated if contrast media is injected into stensen's duct? | partiod |
| name three bones that composes the skull cap | frontal, occipital, parietal |
| what suture seperates the two parietal bones | saggital |
| name the structure that will be best demonstrated with a SMV projection of the skull | base of the cranium |
| what is a reliable way to check for rotation on a lateral skull radiograph | mandibualr rami superimposition |
| if the orboitomental line is perpendicualr to the film for a towne's position, how much caudal angle is required | 30 degrees |
| the orbitomeatal line is perpendicualr to the film and the CR is angles 15 degrees cephalic, what postion is this? | reverse modified caldwell (AP) |
| name three of the auditroy ossicles | incus, stapes, malleus |
| for an SMV projection (basilar projection), what line is parallel to the plane of the film? | infraorbitalmeatal line |
| if the foramen magnum is not wll visualized ona towne's radiograph of the skull, what must be done to correst it | increase CR angle caudally |
| what is the name of the structure that houses the pitutary gland | sella turcica |
| what structure must be entirely in front of both petrous pyramids on an SMV radiograph of the skull | manbible |
| t/f the ethomid is a facial bone | f |
