33
Q

lateral flexion

A

the bending of the neck or body toward the right or left side.

Movement of a body region in a circular manner

36
Q

pronation

upward movement of the scapula and shoulder

41
Q

reposition

A

returning the thumb to its anatomical position next to the index finger

42
Q

rotation

A

occurs straight across the long axis of the bone

54
Q

oblique

A

occurs at an angle that is not 90 degrees

55
Q

spiral

bone segments are pulled apart as a result of a twisting motion

56
Q

comminuted

A

several breaks result im many small pieces between two large segments

57
Q
