Angulation of the central ray may be required
1. to avoid superimposition of overlying structures.
2. to avoid foreshortening or self-superimposition.
3. to project through certain articulations.
The body habitus characterized by a long and narrow thoracic cavity and low, midline stomach and gallbladder is the
The four types of body habitus describe
differences in visceral shape, position, tone, and motility
very large individual with short, wide heart and lungs; high transverse stomach and gallbladder; and peripheral colon; usually demonstrate the greatest motility
average, athletic, most predominant type
somewhat thinner and a little more frail, with organs positioned somewhat lower
smaller in the extreme, with a long thorax; a very long, almost pelvic stomach; and a low medial gallbladder. The colon is medial and redundant.

Avulsion fracture
avulsion fracture
a small bony fragment pulled from a bony process as a result of a forceful pull of the attached ligament or tendon.
comminuted fracture
one in which the bone is broken or splintered into pieces.
torus fracture
a greenstick fracture with one cortex buckled and the other intact
compound fracture
an open fracture in which the fractured ends have perforated the skin.
The plane that passes vertically through the body, dividing it into anterior and posterior halves, is termed the
midcoronal plane
median sagittal, or midsagittal, plane
passes vertically through the midline of the body, dividing it into left and right halves.
Any plane parallel to the MSP is termed
a sagittal plane
midcoronal plane
perpendicular to the MSP and divides the body into anterior and posterior halves.
transverse plane
passes through the body at right angles to a sagittal plane.
Movement of a part toward the midline of the body is termed
movement of the foot caused by turning the ankle outward
foot motion caused by turning the ankle inward
movement of a part away from the midline
The term that refers to parts closer to the source or beginning is
refers to that which is toward the head
that which is toward the feet

Yellow bone marrow
composed mainly of fat cells and stores triglycerides for use as an energy reserve
decubitus position
used to describe the patient who is recumbent (prone, supine, or lateral) with the central ray directed horizontally.
Which of the following are characteristics of the hypersthenic body type?

lying prone
ventral decubitus position
Which of the following devices should not be removed before positioning for a radiograph?
1. An antishock garment
2. A pneumatic splint
antishock garment
used when a patient has suffered a traumatic incident and is suffering from internal bleeding; it functions to slow the rate of bleeding.
air cast
used to temporarily support a fractured limb until surgery and/or a more permanent cast is in place
Both antishock garments and air splints are
