The negative side of the x-ray tube.
What is the cathode?
The maximum permissable dosage for the lens of the eye.

The anatomy used for the caudal border of a lateral thoracic view.
What is the first lumbar vertebrae?
Radiographic view that is obtained when the patient is lying in dorsal recumbency.
What is a ventrodorsal (VD) view?
The striking surface for electrons inside of the x-ray tube, that can be rotating or stationary.
What is the anode?
The lining found in PPE that protects the employee from radiation exposure.

Anatomy that can be evaluated on a thoracic radiograph?
What are the heart and lungs?
The x-ray beam enters the front of the limb and exits the back of the limb, above the carpus or tarsus.
What is a cranial/caudal (Cr/Ca) view?
The portion of the cathode that produces the "electron cloud" when it is heated.

C-shaped component that focuses the electrons toward the anode.
What is the focusing cup?
The types of cells most affected by ionizing radiation.
What are rapidly dividing cells?
Controls the voltage (which will determine how fast the x-rays move) from the cathode to the anode.
