| The superior-most point of the cranium is called the: | vertex |
| When a hypersthenic patient lies supine on the table, which of the following adjustments is necessary to correct the head position for AP projections of the cranium: | place sponges under the occipital region to reduce the backward tilt of the head |
| In the lateral skull position, which of these is parallel to the plane of the film: | the midsagittal plane |
| Which of the following lines is perpendicular to the plane of the film in the Caldwell Method: | OML |
| Which of the following sutures separates the frontal and parietal bones: | coronal |
| Which of the following bones are paired: | temporal |
| Which of the following diseases is a name for the overproduction of bone? | Paget's disease |
| An increase in accumulation of cerebrospinal fluid is called: | hydrocephalus |
| An inflammation of the brain is known as: | encephalitis |
| The pituitary gland is located in the: | sella turcica |
| When positioning a patient for AP axial projection (Towne method) which of the following will produce an image with the structures properly visualized: | the OML is perpendicular to film and CR is angled 30 caudal |
| When positioning for submentovertical projection, which of the following is correct: | the CR is directed perpendicular to the IOML |
| The smooth elevation between the superciliary arches is the: | glabella |
| Which of the following are used as evaluation criteria for the AP axial skull projection (Towne Method): | Posterior clinoids are visible within the foramen magnum and penetration of occipital bone without excessive density at teh lateral borders of skull |
| The cranium is composed of how many bones? | 8 |
| The 2 fontanelles located in the midsagittal plane at the superior and posterior angles of the parietal bones are the: | bregma and lambda |
| If the OML and midsagittal plane are perpendicular to the plane of the film and there is no tube angulation, which of the following projections is demonstrated: | PA |
| On a kyphotic patient, which of these projections would best demonstrate the occipital region, petrous pyramids and the sellar structures within the foramen magnum: | Haas |
| Which of the following indicates a properly positioned lateral skull projection: | close alignment with TMJs orbital roof, etc |
| In a PA projection of the skull with 0 degree tube angulation which of the following is correct: | the petrous ridges will fit the orbits |
| The bony landmark that corresponds to the eyebrow is the: | superciliary arch (ridges) |
| In the full basal (SMV) projection, the CR is directed: | perpendicular to the IOML |
| In the lateral projection for the sella turcica, the CR is directed: | 3/4 inches anterior and 3/4 inches superior to the EAM |
| A patient received a blow to the glabellar region of the frontal bone. Which of the following would best demonstrate that region of the cranium: | OML perpendicular to plane of film, CR perpendicular to plane of film, patient PA |
| In the PA projection (Caldwell method) with a central ray angulation of 15 degrees caudal, which of the following best describes the location of the petrous ridges: | they should lie in the lower 1/3 of the orbit |
| The cross table lateral skull projection on a trauma patient reveals air-fluid levels in the sphenoid sinus. This is an indication of which of the following: | basal skull fracture |
| When assessing an SMV projection, what is correct? | the distance between lateral borders of skull and mandibular condyles should be equal on both sides, cranial base is to be well visualized, and the mandibular symphysis should be superimposed over anterior frontal bone |
| Which of the following is a benign tumor containing blood vessels? | hemangioma |
| From which cranial bone do pterygoid processes project inferiorly: | sphenoid |
| The zygomatic process projects off of which of the following: | temporal bone |
| In the adult, an average 7 degree angle difference exists between the OML and the: | infraorbitomeatal line |
| While the radiographer is obtaining skull radiographs of a patient, which of the following are true in regard to patient care: | Many patients are offended when another person touches their face and recumbent positioning of the skull causes more strain on the patient's muscles |
