D. Parotid

Explanation:

Parotid is the largest of the salivary glands, located in an excavation limited above by the zygomatic arch, ahead by the posterior edge of the jaw and behind by the ear canal. It weighs about 25 grams. It is traversed by 3 important structures: the facial nerve, the retromandibular vein and the left external carotid artery. The parotid produces the greatest amount of saliva predominantly serous.

Sialogram It is an x-ray of the salivary ducts and glands. The latter are located on each side of the face and secrete the saliva inside the mouth.

The exam is done by an X-ray technician in the radiology room of the hospital or in the doctor's office. The patient may be given a sedative before the procedure.

You will be asked to lie on your back on the x-ray table. An x-ray is taken before injecting the contrast medium to ensure that there are no stones that block it from entering the ducts.

A catheter (a small flexible catheter) is inserted through the mouth into the salivary gland duct. The contrast medium is then injected into the duct so that it appears on the x-ray. Radiographic plates are taken from many different positions.
