What could a knot in your neck under the jawbone be that gets larger when eating but the CT shows normal salivary glands?

That sounds like the sub-mandibular salavary gland... Swelling while eating is the key. I'm not surprised that the MRI didn't show anything, as there can be causes that don't show up on an MRI, such as scarring that blocks the duct [tube] from the gland to the floor of the mouth under the tongue... You really need to seek advice from an Ear Nose & Throat doctor to get an accurate diagnosis... Causes can be from a small stone blocking the duct to something pretty serious... I've placed a British URL below for you to review.
I agree with the above poster. If you want to know for sure then take a tablespoon of lemon juice and see what happens after that (won't hurt you) but if it swells then the above poster is correct. I agree also that you need a specialist and a more tests done.

What are the structural modifications in the salivary glands that allow them to carry out their functions?
The structural modification in the salivary glands that allow them to carry out their functions are the different sized glands and their location. The larger of the two glands is the parotid gland. The smaller of the two salivary glands is the submandibular gland.
What receives proteins and materials from the er packages them and distributes them?
The Golgi apparatus is present in larger numbers and is most highly developed in cells that secrete protein, .such as the cells of the salivary glands or the pancreas (in animal cells).
Where would pseudostratified columnar epithelium be found?
lines the ducts of some glands and portions of the male urethra
Which is bigger the pituitary glands or pineal glands?
The Pineal gland is the larger of the two.
Which sudoriferous glands are larger and are found in the axillae and around the genitals?
Apocrine (sweat glands are apocrine glands!/in axillary and genital areas)
Enzymes secreted by the salivary glands?
The enzyme secreted by salivary glands is salivary amylase that acts on cooked starch, converts it to maltose and acts on uncooked starch,converts it to dextrose. Saliva also acts as a lubricant after the mastication of food into a bolus to ease the process of swallowing and peristalsis in the oesophagus.
Why are salivary glands so much larger in rats?
Here is my BS answer followed by a good lead: Rats over time have survived mainly as decomposers much like worms and flies. They eat our waste and then break it down further, but that must require an extraordinarily wide range of foods that are edible to them. Overly developed saliva glands allowed certain rate to proliferate more and over time became intrinsic to their being.
Salivary gland tumors?
DefinitionSalivary gland tumors are abnormal cells growing in the ducts that drain the salivary glands.Alternative NamesTumor - salivary ductCauses, incidence, and risk factorsThe salivary glands are located around the mouth. They produce saliva, which moistens food to help with chewing and swallowing.Saliva contains enzymes that begin the digestion process, and help cleanse the mouth by washing away bacteria and food particles. By keeping the mouth moist, saliva helps to keep dentures, retainers, or other orthodontic appliances in place.There are three pairs of major salivary glands. The largest are the parotid glands, located in each cheek over the jaw in front of the ears. Two submandibular glands are at the back of the mouth on both sides of the jaw. Two sublingual glands are under the floor of the mouth. There are also thousands of minor salivary glands around the rest of the mouth.All of the salivary glands empty saliva into the mouth through ducts that open at various locations in the mouth.Salivary gland tumors are rare, especially in children. Swelling of the salivary glands is most commonly due to:Abdominal surgeryCirrhosis of the liverInfectionsOther cancersSalivary duct stonesSalivary gland infectionsSarcoidosisSjogren syndromeThe most common type of salivary gland tumor is a slow-growing noncancerous (benign) tumor of the parotid gland that gradually increases the size of the gland. However, some of these tumors can be cancerous (malignant).Malignant salivary gland tumors are usually carcinomas.SymptomsA firm, usually painless swelling in one of the salivary glands (in front of the ears, under the chin, or on the floor of the mouth); the size of the swelling gradually increases.Difficulty moving one side of the face, known as facial nerve palsySigns and testsAn examination by a health care provider or dentist shows a larger-than-normal salivary gland, usually one of the parotid glands.Tests may include:X-rays of the salivary gland (called a ptyalogram or sialogram) to look for a tumorCT scan or MRI to confirm that there is a growth, and to see if the cancer has spread to lymph nodes in the neckSalivary gland biopsy or fine needle aspiration to determine whether the tumor is benign or malignantTreatmentThe recommended treatment is usually surgery to remove the affected salivary gland. If the tumor is benign, no other treatment is usually needed.Radiation therapy or extensive surgery may be needed if the tumor is cancerous. Chemotherapy is sometimes used in patients who are considered high risk, or when the disease has spread beyond the salivary glands.Expectations (prognosis)Most salivary gland tumors are noncancerous and slow growing. Removing the tumor with surgery usually cures the condition. In rare cases, the tumor is cancerous and further treatment is needed.ComplicationsCancerous tumors may cause further complications, including spread to other organs (metastasis).Rarely, surgery to remove the tumor can injure the nerve that controls movement of the face.Calling your health care providerCall your health care provider if:You have pain when eating or chewingYou notice a lump in the mouth, under the jaw, or in the neck that does not go away in 2 - 3 weeks or is getting largerReferencesNational Comprehensive Cancer Network Clinical Practice Guidelines in Oncology: Head and Neck Cancers.
