Study These Flashcards
A

25
4 characteristics of inflammation
1- swelling 2- reddening 3- heat at the site 4- pain
26
Difference between acute and chronic conditions
Acute- characterized by sudden onset Chronic- are long durations
27
Difference between benign and malignant
Benign- lesions that are limited in growth & remain @ one site Malignant- are cancers that grow more rapidly; invade surrounding structures & can spread (metastasize) to distant sites
28
Define anterior as it relates to radiographic positioning
Forward or front portion of the body or body part
29
Define posterior as it relates to radiographic positioning
Backwards or back portion of the body or body part
30
Define cephalad as it relates to radiographic positioning
Pertaining to the head, towards the head
31
Define caudad as it relates to radiographic positioning
Away from head
32
Define superior as it relates to radiographic positioning
Above , towards the head
33
Define inferior as it relates to radiographic positioning
Below, farther from the head
34
Define internal as it relates to radiographic positioning
Deep, near the center of the body or part
35
Define external as it relates to radiographic positioning
To the outside, @ or near the surface of the body or part
36
Define medial as it relates to radiographic positioning
Toward the center of the body or center of the part
37
Define lateral as it relates to radiographic positioning
The side, away from the center, to the left or right
38
Define proximal as it relates to radiographic positioning
Towards the source or point of origin
39
Define distal as it relates to radiographic positioning
Away from the source or point of origin Ex: the wrist is distal to the elbow, being farther from the point of origin of the arm, which is @ shoulder
40
Define recumbent as it relates to radiographic positioning
Lying down, The position is further described by adding name of body surface on which patient is lying Dorsal recumbent, lateral recumbent, ventral recumbent
41
Define upright as it relates to radiographic positioning
Erect, standing or seated
42
Define decubitus position as it relates to radiographic positioning
Patient is recumbent with CR horizontal or parallel to floor Position is named according to body surface on which Patient is lying: Lateral decubitus ( left or right), dorsal decubitus, ventral decubitus
43
Define lateral position as it relates to radiographic positioning
Placement of body or part with the Sagittarius plane parallel to the IR. It is named according to the side adjacent to the radiographic table or IR
44
Define oblique position as it relates to radiographic positioning
Achieved when body part or entire body is placed so that the coronal plane is not parallel with radiographic table or IR. The description is usually stated as a degree or rotation, either frl.a body plane or towards the affected side
45
The center ray enters the anterior surface and exits the posterior surface of the body or atomic structure
AP anteroposterior projection
46
The central ray enters the posterior surface and exits the anterior surface of the body or anatomic structure
PA posteroanterior projection
47
That which the Sagittal plane of the body or body part is parallel to the IR
Lateral projection
48
That in which the body is rotated so that the CR travels through the body on An oblique plane, rather than following an anatomic plane
Oblique projection
49
A radiographic taken with a longitudinal angulatio. Of the CR of 10 genre's or more
Axial projection
50
Produced by directing the CR to "skim" the profile of the subject
