salivary gland
(noun)
any of several exocrine glands that produce saliva to break down carbohydrates in food enzymatically
Examples of salivary gland in the following topics:
-
Mumps
- The common symptoms of mumps include inflammation of the salivary glands, pancreas, and testicles; fever, and headache.
- Swelling of the salivary glands, specifically the parotid gland, is known as parotitis, and it occurs in 60–70% of infections and 95% of patients with symptoms .
- As with any inflammation of the salivary glands, the level of amylase in the blood is often elevated.
- Patients are advised to avoid acidic foods and beverages, since these stimulate the salivary glands, which can be painful.
- This child with mumps displays the typical swelling of the salivary glands caused by the mumps virus.
-
Divisions of the Autonomic Nervous System
- Example functions of the PSNS include dilating blood vessels leading to the GI tract and stimulating salivary gland secretion.
- The PSNS typically functions in contrast to the SNS by dilating blood vessels leading to the GI tract, causing constriction of the pupil and contraction of the ciliary muscle to the lens to enable closer vision, and stimulating salivary gland secretion, in keeping with the rest and digest functions.
-
Glandular Epithelia
- There are two major classifications of glands: endocrine glands and exocrine glands.
- Examples of exocrine glands include the sweat glands, salivary glands, mammary glands, the pancreas, and the liver.
- An endocrine gland is its counterpart.
- Examples of endocrine glands include the adrenal glands, located atop the kidneys and responsible for the secretion of certain hormones such as adrenaline, cortisol, and others.
- The sebaceous glands are microscopic glands in the skin that secrete an oily/waxy matter, called sebum, to lubricate and waterproof the skin and hair of mammals.
-
Sjögren's Syndrome
- Sjögren's syndrome is an autoimmune disease in which immune cells attack and destroy the exocrine glands that produce tears and saliva.
- A physical examination can reveal dryness on the surface of the eye, and a biopsy of the lip can reveal lymphocytes clustered around salivary glands, and damage to these glands due to inflammation.
- Ultrasound examination of the salivary glands is the simplest confirmatory test and has the added advantage of being non-invasive with no complications.
- If lesions are observed within the salivary glands, it is strongly indicative of Sjögren's syndrome.
- Prescription drugs are also available to help stimulate salivary flow, such as cevimeline (Evoxac) and pilocarpine.
-
Mouth
- The mouth is also known as the oral cavity, and within the oral cavity sits the tongue, the soft and hard palate, the uvula, and numerous salivary glands.
- Saliva is projected out from three main pairs of salivary glands: the large parotid glands near the cheeks, the submandibular glands beneath the mandible, and the sublingual glands beneath the tongue.
-
Overview of the Endocrine System
- The endocrine system is a system of ductless glands that secrete hormones, which are chemical messengers that act at a distance.
- Growth hormone is secreted by the pituitary gland into a nearby bed of blood vessels to coordinate proportionate growth of an organism.
- The endocrine system is a system of ductless glands that secrete hormones within specific organs.
- Hormones are secreted by two types of glands: exocrine glands and endocrine glands.
- Exocrine glands include certain sweat glands, salivary, pancreatic and mammary glands.
-
Processes and Functions of the Digestive System
- To accomplish this moistening goal, the salivary glands produce an estimated three liters of saliva per day.
- The nervous pathway involved in salivary excretion requires stimulation of receptors in the mouth, sensory impulses to the brain stem, and parasympathetic impulses to salivary glands.
-
Digestive Properties of the Stomach
- EGF is a low-molecular-weight polypeptide first purified from a mouse's submandibular gland, but since found in many human tissues including the submandibular and parotid glands.
- Salivary EGF, which seems also regulated by dietary inorganic iodine, plays also an important physiological role in the maintenance of oroesophageal and gastric tissue integrity.
- The pyloric gland, found in the stomach, secretes gastrin and other hormones.
- The cardiac gland, found in the stomach, secretes gastrin and other hormones.
- The fundic gland, found in the stomach, secretes gastrin and other hormones.
-
Overview of the Parathyroid Glands
- The parathyroid glands are small endocrine glands in the neck that produce parathyroid hormone.
- The parathyroid glands are small endocrine glands in the neck that produce parathyroid hormone.
- Humans usually have four parathyroid glands, which are usually located on the rear surface of the thyroid gland, or, in rare cases, within the thyroid gland itself or in the chest.
- The parathyroid glands are four or more small glands, about the size of a grain of rice, located on the posterior surface (back side) of the thyroid gland.
- The parathyroid gland in relation to the thyroid gland.
-
Sweat (Sudoriferous) Glands
- Sweat glands, also known as sudoriferous glands, are distributed over most of the body surface.
- Sweat glands, also called sudoriferous glands, are simple tubular glands found almost everywhere on our body.
- The other kind of sweat glands are known as apocrine glands.
- Unlike eccrine glands, the exact function of apocrine glands is unknown and debated.
