| 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) |
| acidophil granule | A granule that stains with an acid dye such as eosin. Synonym: oxyphil granule. (05 Mar 2000) |
| acrosomal granule | The single glycoprotein rich granule within an acrosomal vesicle, which results from the coalescence of proacrosomal granule's. (05 Mar 2000) |
| alpha granule | A granule of an alpha cell that was named as the first of several kinds or because it was acidophilic. (05 Mar 2000) |
| Altmann's granule | A granule that has an affinity for fuchsin. Synonym: Altmann's granule. (05 Mar 2000) |
| amphophil granule | A granule that stains with both acid and basic dyes. (05 Mar 2000) |
| atrial granule serine proteinase | <enzyme> Converts pro-atrial natriuretic factor to anf by cleaving the arg98-ser99 bond; n-terminal 26-residue amino acid sequence given in first source Registry number: EC 3.4.21.- (26 Jun 1999) |
| azurophil granule | <cell biology> Primary lysosomal granules found in neutrophil granulocytes, contain a wide range of hydrolytic enzymes. Sometimes referred to as primary granules to distinguish them from the specific or secondary granules. (02 Jan 1998) |
| Babes-Ernst granule | <microbiology> Metachromatic intracellular deposits of polyphosphate found in Corynebacterium diphtheriae when the bacteria are grown on sub optimal media. The granules stain reddish with methylene blue or toluidine blue. (02 Jan 1998) |
| basal granule | <cell biology> Structure found at the base of eukaryotic cilia and flagella consisting of a continuation of the nine outer sets of axonemal microtubules but with the addition of a C tubule to form a triplet (like the centriole). May be self replicating and serves as a nucleating centre for axonemal assembly. Anchored in the cytoplasm by rootlets. Synonymous with kinetosome. (18 Nov 1997) |
