gland (glnd)

n.

1. A cell, a group of cells, or an organ that produces a secretion for use in or for elimination from the body.

2. Any of various organs, such as lymph nodes, that resemble true glands but perform a nonsecretory function.

---

Gland

A collection of cells whose function is to release certain chemicals, or hormones, which are important to the functioning of other, sometimes distantly located, organs or body systems.

Mentioned in: Acromegaly and Gigantism, Addison's Disease, Cushing's Syndrome, Pancreatitis

gland

Etymology: L, glans, acorn

any one of many organs in the body comprising specialized cells that secrete or excrete materials not related to their ordinary metabolism. Some glands lubricate; others, such as the pituitary gland, produce hormones; hematopoietic glands, such as the spleen and certain lymph nodes, take part in the production of blood components. Exocrine glands discharge their secretions into ducts. They may be classified by the shape and complexity of their duct systems. Endocrine glands are ductless and discharge their secretions directly into the blood or interstitial fluid. glandular, adj.

Exocrine glands: structural classification

---

gland,

n an organ with specialized cells that secretes or excretes materials into the body. Classified into exocrine glands that secrete via ducts and endocrine glands that secrete directly into the bloodstream.

---

gland(s),

n/n.pl an organ producing a specific product or secretion.

gland, parotid salivary,

n the largest of the major salivary glands; its anterior position is situated between the ramus of the mandible, its posterior portion between the mastoid process and sternocleidomastoid muscle, and inferior to the zygomatic arch; irregularly wedge shaped, with the lateral surface flattened and the medial aspect more or less pointed toward the pharyngeal wall. Its secretion, which is serous, travels the parotid duct (Stenson's duct) to empty into the oral cavity at the ductal opening at the parotid papillae on the buccal mucosa opposite the maxillary molar teeth.

gland, pituitary,

n (hypophysis), an endocrine gland located at the base of the brain in the sella turcica. The pituitary gland is composed of two parts: the pars nervosa, which is an extension of the anterior part of the hypothalamus, and the pars intermedia, which is an epithelial evagination of secretory tissue from the stomodeum of the embryo. By its structural and functional relationships with the nervous system and the endocrine glands, it acts as a mediator of both the nervous system and the endocrine system.

gland, sublingual salivary,

n the smallest of the major salivary glands. It lies inferior to the floor of the oral cavity bilateral to the lingual frenum and is in contact with the sublingual depression on the inner side of the mandible. Its numerous ducts open directly into the oral cavity bilateral to the lingual frenum and join to form the sublingual duct (duct of Bartholin's), which enters into the submandibular duct (Wharton's duct). Its secretion is mucous in nature.

gland, submandibular salivary,

n a major salivary gland that has an irregular form and is situated in the submandibular space, bordered anteriorly by the anterior belly of the digastric muscle and posteriorly by the stylomandibular ligament. Its mucoserous section is carried by the submandibular duct (Wharton's duct), whose openings lie at a small papilla (submandibular caruncle) bilateral to the lingual frenum.

gland, thymus,

n See thymus.

glands, Blandin and Nuhn's,

n.pr See spots, Fordyce's.

glands, endocrine,

n.pl a gland of internal secretion; a hormone-secreting gland (e.g., the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, ovaries, and testes).

glands, lacrimal,

n.pl the ducted (exocrine) glands that produce lacrimal fluid, commonly called
tears. See also lacrimal apparatus.

glands, minor salivary,

n.pl the glands located at the posterior aspect of the dorsum of the tongue posterior to the circumvallate papillae (von Edner's) and along the lateral surface of the tongue; also located in the palate, floor of mouth, labial mucosa, and buccal mucosa. The secretion is mucous, and they do not have named ducts. Older term:
accessory salivary glands. See also salivary glands, von Edner's.

glands, salivary,

n.pl the glands in the oral cavity that secrete saliva. Three major salivary glands contribute their secretions to form the whole saliva; the minor mucous glands found within oral mucosa contribute a lesser amount. The major salivary glands are the parotid, submandibular, and sublingual.

gland

An aggregation of cells which secretes or excretes a substance. There are two main groups of glands: (1) The endocrine glands which have no duct and whose secretion (a hormone) is absorbed directly into the blood. Examples: adrenal gland, pineal gland, pituitary gland, thyroid gland. (2) The exocrine glands whose secretion reaches the surface by means of ducts. There are three main types of secretion by exocrine glands: the serous glands which secrete a watery substance rich in proteins (e.g. lacrimal gland, sweat glands), the mucous glands which secrete mucus, a viscous product (e.g. goblet cells), and the sebaceous glands which secrete a lipid substance (e.g. meibomian glands).
accessory lacrimal gland's They are the glands of Krause and Wolfring. These glands are histologically identical to the main lacrimal gland, but are located within the eyelids. These glands are responsible for basal (not reflex) tear secretion and appear to be under sympathetic neural control.
gland's of Ciaccio See glands of Wolfring.
ciliary sebaceous gland's See glands of Zeis.
ciliary sweat gland's See glands of Moll.
conjunctival gland Any gland that secretes a substance into the conjunctiva, such as the lacrimal, meibomian, Krause and Wolfring glands or a goblet cell.
gland's of Henle These are not really glands. They are folds in the mucous membrane of the palpebral conjunctiva, situated between the tarsal plates and the fornices, in which there are goblet cells (Fig. G2). Syn. crypts of Henle (strictly speaking this term refers only to the pit-like depressions).
gland's of Krause Accessory lacrimal glands of the conjunctiva having the same structure as the main lacrimal gland. They are located in the subconjunctival connective tissue of the fornix, especially the superior fornix (Fig. G2).
lacrimal gland A compound gland situated above and to the outer side of the globe of the eye. It consists of two portions: (1) a large orbital or superior portion; and (2) a small palpebral or inferior portion. It secretes the middle aqueous layer of the tears through about a dozen fine ducts into the conjunctival sac at the upper fornix although one or two may also open into the outer part of the lower fornix (Fig. G2). See dacryoadenitis; dacryops; fossa for the lacrimal gland; zygomatic nerve; tear duct.
gland's of Manz Tiny glands located near the limbus. They secrete mucin. The existence of these glands in man is not established.
meibomian gland's Sebaceous glands located in the tarsal plates of the eyelids whose ducts empty into the eyelid margin. They are arranged parallel with each other, perpendicular to the lid margin, about 25 for the upper lid and 20 for the lower. They secrete sebum. This sebaceous material provides the outermost oily (or lipid) layer of the precorneal tear film. It prevents the lacrimal fluid from overflowing onto the outer surface of the eyelid. It also makes for an airtight closure of the lids and prevents the tears from macerating the skin. The meibomian glands can be seen showing through the conjunctiva of fair-skinned people as yellow streaks (Fig. G2). Meibomian gland dysfunction (MGD) may be induced by blepharitis, chalazion, contact lens wear (particularly soft lenses) and ageing. The most common sign is a cloudy or absent secretion upon expression with symptoms of a mild dry eye. Hot compresses and lid massage will cure more than half of the patients; oral tetracycline will help in many of the others. Syn. palpebral follicles; tarsal glands. See posterior blepharitis; chalazion; precorneal film; internal hordeolum; keratoconjunctivitis sicca; meibomianitis; tarsus; Tearscope plus.
gland's of Moll Sweat glands of the eyelids. They are situated in the region of the eyelashes (Fig. G2). Syn. ciliary sweat glands.
tarsal gland's  See meibomian glands.
gland's of Wolfring Accessory lacrimal glands of the upper eyelid situated in the region of the upper border of the tarsus (Fig. G2). Syn. glands of Ciaccio.
gland's of Zeis Sebaceous glands of the eyelids which are attached directly to the follicles of the eyelashes. Their secretion contributes to the oily layer of the precorneal film (Fig. G2). Syn. ciliary sebaceous glands. See marginal blepharitis; hordeolum.

Patient discussion about Galeati's glands.

Q. Anyone know if there is a connection between Fibromyalgia and your Thyroid gland? I have Fibromyalgia and I read that if your diagnosed with this you can have Thyroid problems also. If anyone knows out there please inform me. Many thanks.

A. Below is an interesting article on the subject. A significant percentage of the estimated 20 million people with hypothyroidism end up also being diagnosed with fibromyalgia. Some experts believe that like most cases of hypothyroidism, fibromyalgia is also autoimmune in nature. Others believe that fibromyalgia may be one manifestation of an under active metabolism – hypometabolism – and is therefore one variation on thyroid dysfunction.
http://thyroid.about.com/cs/fibromyalgiacfs/a/fibrothyroid.htm

Q. my friend ate a bar of chocolate and now her left neck gland is swollen any ideas why? no other symptoms

A. it can be an infection -just like brandon said- or although this is rare, it can also be an allergic reaction.
if it is an infection, you can usually find such other infection symptoms like : fever, pain in that swollen area, increased white blood cells (in blood work test), etc.

if it is an allergy, usually it will fade away itself in couple of days, or you can just try to consume anti-allergic drugs, such as : loratadine and maybe combined with dexamethasone.

Good luck, and stay healthy always..
