19
Q

movement laterally away from the midline is called

A

abduction

20
Q

movement medially towards midline is called

A

adduction

21
Q

movement around a longitudinal axis towards the midline is called

A

medial rotation

22
Q

movement around a longitudinal axis away from the midline is called

A

lateral rotation

23
Q

what is the term for a windmill like motion which combines the other types of movement

A

circumduction

24
Q

what are x rays usually used to image and how

A

dense tissue (bone) as when x-rays pass through subject the x-rays are detected by a film on the other side and the x-rays don’t penetrate the dense tissue

25
Q

how can soft tissue be visualised by x-rays

A

contrast media eg. barium, iodine and other heavy metals - used to detect blockages in blood vessels and observe GI tract

26
Q

what are CT scans and what are they used to image

A
  • computerised tomography scans use x-rays in a rotating tube with guns and detectors
  • image is reconstructed by a computer can measure soft and dense tissue with dense tissue still the brightest
  • 3D reconstruction possible
27
Q

what is MRI imaging and how are they used

A
  • Magnetic Resonance Imaging uses radio waves and nucleus magnetic resonance of hydrogen nuclei (detects water in tissues)
    -computer generated
    -high resolution visualisation of soft tissues and ligaments
    -subject must stay still for long periods
28
Q

What are ultrasounds and how are the used

A
  • gives out and records reflections of ultrasonic waves
  • often used for foetuses in pregnancy
  • safe and accessible but low resolution
