tis·sue (tsh)

n.

An aggregation of morphologically similar cells and associated intercellular matter acting together to perform specific functions in the body. There are four basic types of tissue: muscle, nerve, epithelial, and connective.

tissue

[tish′o̅o̅]

Etymology: Fr, tissu, fabric

a collection of similar cells in a matrix acting together to perform a particular function.

tissue (tish´oo),

n an aggregation of similarly specialized cells united in the performance of a particular function.

tissue adhesives,

n agents or materials that may be used to seal two cut tissue surfaces together or cover a surgically exposed surface such as butyl cyanoacrylate, which is used to cover palatal donor sites in periodontal surgery.

tissue, compression of,

n See tissue displaceability.

tissue conditioning,

n a disciplined program of patient-performed plaque control measures designed for gingiva that is soft, spongy, and bleeds easily from poor oral hygiene habits, in order to improve gingival health before subgingival scaling is performed.

tissue, connective,

n the binding and supportive tissue of the body; derived from the mesoderm; depending on its location and function, it is composed of fibroblasts, primitive mesenchymal cells, collagen fibers, and elastic fibers, with associated blood and lymphatic vessels and nerve fibers.

tissue, critical,

n See tissue, hyperplastic.

tissue, hyperplastic,

n in dentistry, excessively movable tissue about the mandible or maxillae resulting from increases in the number of normal cells.

tissue, interdental,

n the gingivae, cementum of the teeth, free gingival and transseptal fibers of the periodontal membrane (ligament), and alveolar and supporting bone.

tissue molding,

n See border molding.

tissue, peripheral,

n See border structures.

tissue, redundant,

n See epulis fissuratum.

tissue sloughing,

n a surface layer of flesh peeling away. Possible causes are extensive exposure to topical anesthetic, overly abrasive toothpaste, smokeless tobacco, tissue burn, or mouthrinses. Also called
epithelial desquamation.

tissue, subjacent,

n the structures that underlie or are in border contact with a denture base; they may or may not have a supporting relationship to the overlying base.

tissue-borne partial denture,

n See denture, partial, tissue-borne.

tissue

a group or layer of similarly specialized cells that together perform certain special functions. For anatomically specific tissues see under their identifying titles, e.g. adipose, connective.

tissue death

see necrosis.

tissue density

the penetrability of tissue by x-rays, bone and tooth being most dense, blood and soft tissue the next, fat the next, and gas and air least.

tissue edema

an abnormal accumulation of tissue fluid.

tissue factor

see tissue thromboplastin.

tissue fluid

the extracellular fluid that constitutes the environment of the body cells. It is low in protein, is formed by filtration through the capillaries, and the excess drains away as lymph. See also interstitial fluid.

tissue inhibitors

inhibitors of fibrinolysis; present in placenta.

indifferent tissue

undifferentiated embryonic tissue.

tissue necrosis fever

fever caused by pyrogens released by necrotic pyrogens.

tissue plasminogen activator

see plasminogen activator.

tissue reacting agent

substances that have a poorly defined but advantageous local effect on tissues.

tissue receptor site

a cell receptor common to cells of a particular tissue.

tissue residue

residues of chemical substances that are unacceptable to local pure food legislation especially sulfonamides, estrogens, chlorinated hydrocarbons, heavy metals. These are thought or known to have a deleterious effect on people eating or drinking the relevant animal product. See also chemical food residue.

tissue sensitivity

the susceptibility of individual tissues to injury by x-ray. The injury may be by way of inflammation, necrosis or cessation of cell growth. Fast-growing tissues in which the cells have a high mitotic index are the most sensitive, especially gonads, germinative layer of skin and erythropoietic tissues.

supportive t's

cartilage and bone.

tissue therapy

see glandular therapy.

tissue typing

identification of tissue types for purposes of predicting acceptance or rejection of grafts and organ transplants. The process and purposes of tissue typing are essentially the same as for blood typing. The major difference lies in the kinds of antigens being evaluated. White blood cells, particularly lymphocytes, are used for tissue typing. The acceptance of allografts depends particularly on the matching of MHC antigens. If the donor and recipient are not MHC identical, the allograft is rejected. See also typing.

Patient discussion about hyperplastic tissue.

Q. My neighbor's kid had a lens dislocation due to Marfan's disease. Is this a contagious thing? My neighbor's have a sweet 8 year old boy. he had a lens dislocation due to a connective tissue disease named Marfan (I think that the name). It sounds like a very serious condition. My boy is playing with this kid several hour a week. should I take him to the GP to see that his is not infected with this marfan thing?

A. Don't worry. Marfan's syndrome is a connective tissue disease that is genetic. This means that You can't "get" this disease. Either you are borne with it or you will never suffer from it.
lens dislocation is a known symptom of marfan's syndrome, and is not connected to infectious diseases.

Q. I could feel hard tissues in my breasts.I suspect it the other way, any idea what it may be? I could feel hard tissues in my breasts. While reading article about breast cancer, I happened to note that these may be simple cyst and there is nothing to worry. My friend too had cyst and treated by the doctor with needle by removing the fluid out. But I suspect it the other way, any idea what it may be?

A. you cannot just guess it, I do encourage you to go see your doctor (oncologist is recommended), to have your breast checked.
first, your doctor will have a physical examination on you, and then it might help to find the correct diagnose by using some imaging procedures (ultrasound, mammography), or even by doing a fine needle aspiration on the lump. then it will be checked under microscopes to get the specific "what is that lump?"

Q. I want to get cure for asthma and develop my cardiac tissue. What is the best exercise for me to do? This is Daron, 20/m. I have had asthma since I was 3 yrs old, and suffer from exercise induced asthma as well as weather and food. Running is the worst thing that induces asthma in me. I want to get cure for asthma and develop my cardiac tissue to ensure fitness. What is the best exercise for me to do? I will be very thankful if I get suitable suggestion or advice..

A. daron,their is no cure for asthma--asthma is controlled by meds--if you dont have one get a pulmonary DR.--you can try riding a bike,and walking,i was born with asthma and i have the same problem as you,--you can try walking or biking for a little amount of time each day,--you can also try taking your meds before doing any exercize,THere are meds on the market,that can help you to do the things that you like.--mrfoot56---peace
