What Is a Heterogeneous Thyroid? What is a heterogeneous thyroid? A: A heterogeneous thyroid is a thyroid gland that is not uniform in structure and may indicate a thyroid disorder, explains Health and Nutrition Tips. InnerBody.com notes that the thyroid is a butterfly-shaped gland located in the neck. The thyroid gland encircles the larynx and contributes to the Adam's apple prominence.

What are Parotid Tumors or Parotid Mass: Causes, Symptoms, Treatments, Prognosis, Complications Pleomorphic Adenoma: It is the most common variety of parotid tumor or parotid mass. It is a benign tumor that grows slowly within the parotid gland. Warthin's Tumor: It is the second most common type of parotid tumor or parotid mass. This is also a benign tumor and it can affect both sides of the face.

The Salivary Glands The submandibular, parotid, and sublingual salivary glands in association with the left side of oral cavity. Mumps, a common disease amongst children, is an inflammation of the parotid glands caused by the mumps (myxovirus) virus.The virus spreads from person to person in saliva. If you view t.ost saliva is produced by major or extrinsic salivary glands that lie outside the oral cavity and empty their secretions into it. Minor or intrinsic salivary glands within the oral cavity alter the output slightly (note: extrinsic glands lie outside of oral cavity, intrinsic glands lie within oral cavity).

Chapter 50: The neck The development of the parotid gland is unique in two ways compared with that of the other major salivary glands. First, it is the only salivary gland to become encapsulated after the development of the lymphatic system, resulting in the presence of both intraparotid lymph nodes and lymphatic channels.he parotid gland is located at the angle of the mandible, defining an anatomic area termed the parotid space, which contains the facial nerve, the retromandibular vein, the external carotid artery and its branches, and intraparotid lymph nodes (3).

Bilateral parotid swelling: a radiological review Sialadenosis is defined as a bilateral, persistent, painless, non-inflammatory swelling of the salivary glands, particularly the parotids. The causes include diabetes mellitus, endocrinopathy (hypothyroidism), starvation, medications (thiourea, diuretics), alcohol abuse and heavy metals.

Salivary Gland Tumours Benign tumours. 1  Pleomorphic adenoma (most common) - also called benign mixed tumour: is the most common tumour of the parotid gland and causes over a third of submandibular tumours. 2  Warthin's tumour: second most common benign salivary gland neoplasm, representing about 6-10% of all parotid tumours.

- Of parotid neoplasms, 70-80% are benign. Except for Warthin tumors, benign tumors of the parotid gland are more likely to occur in women than in men. The median age for occurrence of these tumors is in the fifth decade of life. Parotid tumors occur most commonly in Caucasians. The etiology of these tumors is unknown, but the possibility of an adenoma gene currently is under investigation for its involvement in the development of pleomorphic adenomas. The most common benign parotid tumor in children is the mixed tumor.

Salivary Glands - What's Normal? What's Abnormal? The major salivary glands are called the parotid, submandibular and sublingual glands. They all secrete saliva into the mouth: the parotid through ducts near the upper teeth, submandibular into the front portion under the tongue, and the sublingual through multiple ducts in the floor of the mouth.

Original ContributionHeterogeneous Echogenicity of the Thyroid Parenchyma Does Not Influence the Detection of Multi-focality in Papillary Thyroid Carcinoma on Preoperative Ultrasound Staging Among the 811 patients included, US revealed underlying heterogeneous echogenicity of the thyroid parenchyma in 204 (25.2%) and underlying homogeneous echogenicity of the thyroid parenchyma in 607 (74.8%).he diagnostic performance of pre-operative staging US in the detection of multi-focality with respect to the echogenicity of underlying thyroid parenchyma was determined by calculating the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy.

-   Heterogeneous means that there are different compounds in a sample. Heterogeneous is a term used with mixtures and the way I like to think about it is: If you have che … erios, apple jacks, and coco puffs in a bowl you have a heterogeneous mixture because you can physically separate the cereals from each other. heterogeneous echotexture of the uterus means that the muscular  tissue appears varied when viewed by ultrasound. This is an  abnormality that is typically caused by fibro … ids or excessive  growth of endometrial tissue. 1 person found this useful.

Salivary Glands and Saliva Most animals have three major pairs of salivary glands that differ in the type of secretion they produce: 1  parotid glands produce a serous, watery secretion. 2  submaxillary (mandibular) glands produce a mixed serous and mucous secretion.3  sublingual glands secrete a saliva that is predominantly mucous in character.he basic secretory units of salivary glands are clusters of cells called an acini. These cells secrete a fluid that contains water, electrolytes, mucus and enzymes, all of which flow out of the acinus into collecting ducts.

- We call the major salivary glands the parotid, submandibular, and sublingual glands. They all secrete saliva into your mouth, the parotid through tubes that drain saliva, called salivary ducts, near your upper teeth, submandibular under your tongue, and the sublingual through many ducts in the floor of your mouth.alivary gland problems that cause clinical symptoms include: Obstruction: Obstruction to the flow of saliva most commonly occurs in the parotid and submandibular glands, usually because stones have formed. Symptoms typically occur when eating.

Heterogeneous Thyroid Unfortunately, a diagnosis of heterogeneous thyroid may mean some serious thyroid problems. The Thyroid and What It Does. The thyroid is a small gland that is located in the center of the neck, just at the base. This particular gland is responsible for sending out hormones into the body.The hormones distributed by the thyroid gland are generally responsible for delivering energy to individual cells in the body.ypothyroidism is just the opposite of hyperthyroidism – referring to a thyroid gland that is not producing enough of the thyroid hormones, or is under active. The symptoms of hypothyroidism include depression, fatigue and unexplained weight gain due to a slow down in the metabolism.

salivary glands This large duct carries the saliva away from the gland and into the mouth. The position of each of the three pairs of large salivary glands is indicated by their names. Parotid means near the ears; sublingual means under the tongue; and submandibular means under the mandible (that is, under the jaw-bone).unctions of saliva include the following: The saliva from the parotid gland is a rather thin, watery fluid, but the saliva from the sublingual and the submandibular glands contains mucus and is much thicker. The salivary glands are solid structures composed of millions of secretory cells.
