| reflex, stretch | Reflex contraction of a muscle in response to stretching, which stimulates muscle proprioceptors. (12 Dec 1998) |
|---|---|
| pulmonary stretch receptors | Stretch receptors found in the bronchi and bronchioles. Pulmonary stretch receptors are sensors for a reflex which stops inspiration. In humans, the reflex is protective and is probably not activated during normal respiration. (12 Dec 1998) |
| stretch | 1. To reach out; to extend; to put forth. "And stretch forth his neck long and small." (Chaucer) "I in conquest stretched mine arm." (Shak) 2. To draw out to the full length; to cause to extend in a straight line; as, to stretch a cord or rope. 3. To cause to extend in breadth; to spread; to expand; as, to stretch cloth; to stretch the wings. 4. To make tense; to tighten; to distend forcibly. "The ox hath therefore stretched his yoke in vain." (Shak) 5. To draw or pull out to greater length; to strain; as, to stretch a tendon or muscle. "Awake, my soul, stretch every nerve." (Doddridge) 6. To exaggerate; to extend too far; as, to stretch the truth; to stretch one's credit. "They take up, one day, the most violent and stretched prerogative." (Burke) Origin: OE. Strecchen, AS. Streccan; akin to D. Strekken, G. Strecken, OHG. Strecchen, Sw. Stracka, Dan. Straekke; cf. AS. Straeck, strec, strong, violent, G. Strack straight; of uncertain origin, perhaps akin to E. Strong. Cf. Straight. Source: Websters Dictionary (01 Mar 1998) |
| stretch marks | Bands of thin wrinkled skin, initially red but becoming purple and white, which occur commonly on the abdomen, buttocks, and thighs at puberty and/or during and following pregnancy, and result from atrophy of the dermis and overextension of the skin; also associated with ascites and Cushing's syndrome. Synonym: atrophoderma striatum, lineae albicantes, lineae atrophicae, linear atrophy, stretch marks, stria, striae atrophicae, striate atrophy of skin, traction atrophy, vergeture. (05 Mar 2000) |
| stretch receptors | Receptor's that are sensitive to elongation, especially those in Golgi tendon organs and muscle spindles, but also those found in visceral organs such as the stomach, small intestine, and urinary bladder; these receptor's have the function of detecting elongation, and this distinguishes them from baroreceptors, which actually are activated by stretching of the wall of the blood vessel but whose function is to elicit central reflex mechanism reducing the arterial blood pressure. (05 Mar 2000) |
| stretch reflex | Tonic contraction of the muscles in response to a stretching force, due to stimulation of muscle proprioceptors. Synonym: Liddell-Sherrington reflex, muscular reflex, stretch reflex. (05 Mar 2000) |
| rolly-poly | A kind of pudding made of paste spread with fruit, rolled into a cylindrical form, and boiled or steamed. Shaped like a rolly-poly; short and stout. Alternative forms: roly-poly. Source: Websters Dictionary (01 Mar 1998) |
| poly | 1. <prefix> A combining form or prefix denoting many, multiplicity, as polygon, a figure of many angles; polyatomic, having many atoms; polychord, polyconic. 2. <botany> A whitish woolly plant (Teucrium Polium) of the order Labiatae, found throughout the Mediterranean region. The name, with sundry prefixes, is sometimes given to other related species of the same genus. 3. <chemistry> A prefix meaning polymer of, as in polypeptide, polysaccharide, polynucleotide; often used with symbols, as in poly(A) for poly(adenylic acid), poly(Lys) for poly(l-lysine). Origin: G. Polys, much, many Source: Websters Dictionary (21 Jun 2000) |

| poly A | <biochemistry, molecular biology> Polynucleotide chain consisting entirely of residues of adenylic acid (i.e. The base sequence is AAAA.AAAA). Polyadenylic chains of various lengths are found at the 3' end of most eukaryotic mRNAs, the poly A tail. (11 Jan 1998) |
| poly(A) | 1. <abbreviation> Poly(adenylic acid). 2. Iridoid indole alkaloid isolated from Vinca sp.; may have pharmacological applications; falling in this class are vinblastine and vincristine. 3.

A class of basic antibiotic peptides, found in neutrophils, that apparently kill bacteria by causing membrane damage. (05 Mar 2000) |
