Q

projection of the upper or lower limb that is rotated is called “oblique.” This is not a true AP projection and must also include a qualifying term that indicates which way it is rotated, such as medial or lateral rotation

Q

It must also include a qualifying term that indicates which way it is rotated. With a PA oblique projection, the CR enters the posterior surface and exits the anteriorsurface of the body or body part.

Q

A lateral projection is described by the path of the CR. Two examples are the __ of the ankle and the __ of the wrist. The medial and lateral sides are determined with the patient in the anatomic position.

Q

A

Fowlers position

20
Q

A recumbent oblique position with the patient lying on the left anterior side, with the right knee and thigh flexed and the left arm extended down behind the back.

A

Sims position

21
Q

A recumbent (supine) position with knees and hip flexed and thighs abducted and rotated externally, supported by ankle supports.

A

Lithotomy position

22
Q

refers to the side of, or a side view. Specific lateral positions described by the part closest to the IR or the body part from which the CR exits. A true lateral position is always 90°, or perpendicular, or at a right angle, to a true AP or PA projection. If it is not a true lateral, it is an oblique position.

A

Lateral position

23
Q

refers to an angled position in which neither the sagittal nor the coronal body plane is perpendicular or at a right angle to the
IR. Oblique body positions of the thorax, abdomen, or pelvis are described by the part closest to the IR or the body part from which the CR exits.

A

Oblique position

24
Q

This body position, meaning to lie on a horizontal surface, is designated according to the surface on which the body is resting. This term describes a patient who is lying on one of the following body surfaces: back (dorsal), front (ventral), or side(right or left lateral). In radiographic positioning, decubitus is always performed with the central ray horizontal. Decubitus positions are essential for detectingair-fluid levels or free air in a body cavity such as the chest or abdomen, where the air rises to the uppermost part of the body cavity

A

Decubitus position

25
Q

decreases the angle of the joint.

A

Flexion

26
Q

increases the angle as the body part moves from a flexed to a straightened position. This is true for the knee, elbow, and wrist joints.

A

Extension

27
Q

Extending a joint beyond the straight or neutral position.

A

Hyperextension

28
Q

literally means “to turn aside” or “to turn away from the standard or course.” Ulnar deviation is to turn or bend the hand and wrist from the natural position toward the ulnar side, and radial deviation is toward the radial side of the wrist

A

Deviation

29
Q

to decrease the angle (flex) between the dorsum (top of foot) and the lower leg, moving foot and toes upward.

A

Dorsiflexion of foot

30
Q

Extending the ankle joint, moving foot and toes downward from the normal position; flexing or decreasing the angle toward the plantar (posterior) surface of the foot.

A

Plantar flexion of foot

31
Q

is an outward stress movement of the foot at the ankle joint.

A

Eversion

32
Q

is an inward stress movement of the foot as applied to the foot without rotation of the leg.

A

Inversion

33
Q

is a movement backward or the condition of being drawn back.

A

Retraction

34
Q

a rotation or turning of a body part with movement of the anterior aspect of the part toward the inside, or median, plane.

A

Medial rotation

35
Q

a rotation of an anterior body part toward the outside, or away from the median plane.

A

Lateral rotation

36
Q

the lateral movement of the arm or leg away from the body. Another application of this term is the abduction of the fingers or toes, which means spreading them apart.

A

Abduction

37
Q

is a movement of arm or leg toward the body, to draw toward a center or medial line. Adduction of the fingers or toes means moving them together or toward each other.

A

Adduction

38
Q

is a rotational movement of the hand into the anatomic position (palm up in supine position or forward in erect position).

A

Supination

39
Q

is a rotation of the hand into the opposite of the anatomic position (palm down or back).

A

Pronation

40
Q

is a movement forward from a normal position.

A

Protraction

41
Q

is a movement backward or the condition
of being drawn back.

A

Retraction

42
Q

is a lifting, raising, or moving of a part superiorly.

A

Elevation

43
Q

is a letting down, lowering, or moving of a part inferiorly.

A

Depression

44
Q

means to move around in the form of a circle.

A

Circumduction

45
Q

is to turn or rotate a body part on its axis. the midsagittal plane of the entire body, including the head, is rotated.

A

Rotate

46
Q

is a slanting or tilting movement with respect to the long axis.

A

Tilt
