Technically, X-rays refer to the form of radiation used, while this term refers to the actual image produced (such as a chest film).

What is a radiograph?

100

This central, grayish structure on a chest radiograph is the heart.


What is A?

100

This part of the skeleton includes the skull, vertebral column, sternum, and hyoid bone.

What is the axial skeleton?

100

This long bone of the upper arm is labeled as one of the options in the skeleton diagram.

What is the humerus?

100

These joints allow the greatest degree of movement and include ball-and-socket types. 

What are synovial joints? 


100

Shoulders and hips are this multiaxial type with the greatest range. 

What is ball-and-socket?


200

In radiography, dense structures like bone absorb most of the X-ray beam, so few rays hit the film, causing this appearance on the final image.

What is white?

200

These large, dark areas on either side filled with air are the lungs.

What are B?

200

This lighter, soft inner bone layer contains bone marrow.

What is spongy bone (or cancellous bone)?

200

These wrist bones are the carpals. 


What are the carpals?

200

These joints have limited movement, such as between vertebrae or ribs and sternum. 

What are cartilaginous joints? 

200

The base of the thumb is this type, allowing opposition. 


What is a saddle joint?

300

Air-filled structures like the lungs allow most X-ray radiation to pass through and hit the film, so they appear this way on a radiograph.

What is black?

300

This vertical, central white line is often the spine or mediastinum area.

What is C?

300

This protective outer covering of bone contains blood vessels and provides nutrients.

What is the periosteum?

300

The bones of the fingers and toes are collectively called these.

What are the phalanges?

300

These joints allow no movement, like skull sutures. 

What are fibrous joints?

300

Knuckles (metacarpophalangeal joints) are often this biaxial type. 

What is an ellipsoidal (or condyloid) joint? 


400

Muscle, fat, and fluid absorb some but not all X-rays, so they show up this way on an X-ray image.

What are shades of gray?

400

This denser area at the bottom is the diaphragm.

What is D?

400

This space inside long bones stores bone marrow and is the medullary cavity.

What is the medullary cavity (or space where bone marrow is stored)?

400

This large pelvic bone includes the ilium.

What is the ilium?

400

This type of synovial joint allows flexion/extension only, like knees and elbows. 

What is a hinge joint? 


400

Gliding joints are found between these bones in the hands and feet for small sliding movements.

What are the bones of hands and feet (or carpals/tarsals)?

500

Surgical steel or metal implants absorb nearly all X-rays and appear this way due to very high density.

What is white?

500

On a standard PA chest radiograph, this side of the body (patient's left) appears on the right side of the image due to how the film is viewed.

What is the left side of the body?

500

This plate in children's bones allows growth and eventually turns into solid bone. 

What is the growth plate (or epiphyseal plate)?

500

This bone in the neck (not part of the vertebral column) is the hyoid.

What is the hyoid bone?

500

This type allows swivel/rotation, like the proximal radioulnar joint for forearm pronation/supination.

What is a pivot joint?

500

This is Ms. Staunch's first name.

What is Christine?
