| tense | Tight, rigid, or strained; characterised by anxiety and psychological strain. Origin: L. Tensus, pp. Of tendo, to stretch (05 Mar 2000) |
| tense part of the tympanic membrane | The greater portion of the tympanic membrane which is tense and firm, contrasting with the small triangular flaccid part of tympanic membrane. Synonym: pars tensa membranae tympani, membrana tensa, membrana vibrans. (05 Mar 2000) |
| tense pulse | A hard, full pulse but without very wide excursions, resembling the vibration of a thick cord. Synonym: cordy pulse. (05 Mar 2000) |
| tensegrity | <cell biology> The hypothesis that cells can behave like structures in which shape results from balancing tensile and hydrostatic forces. (18 Nov 1997) |
| tensile strength | The maximum stress a material subjected to a stretching load can withstand without tearing. (12 Dec 1998) |
| tensile stress | A stress acting on a body per unit cross-sectional area so as to elongate the body. (05 Mar 2000) |
| tensility | The quality or state of being tensile, or capable of extension; tensibility; as, the tensility of the muscles. Source: Websters Dictionary (01 Mar 1998) |
| Tensilon test | <investigation> In this test the drug Tensilon is administered and the response in muscle strength is then assessed. This test is used to help diagnose myasthenia gravis. In myasthenic patients (and myasthenic crisis), Tensilon administration will result in a temporary improvement in muscle strength. In the case of cholinergic crisis (too much anticholinesterase medication), Tensilon will exaggerate the weakness. (13 Jan 1998) |
| tensin | <cell biology> Actin binding component of focal adhesions and submembranous cytoskeleton. Has SH2 domain and can be tyrosine phosphorylated, speculated that it may lin k signalling systems with the cytoskeleton. (18 Nov 1997) |
| tensio active | Having an effect on surface tension. (18 Nov 1997) |
| tensiometer | A device for measuring tension. Origin: L. Tensio, tension, + G. Metron, measure (05 Mar 2000) |
| tension | 1. The act of stretching. 2. The condition of being stretched or strained, the degree to which anything is stretched or strained. 3. <physics> Voltage. 4. <chemistry> The partial pressure of a gas in a fluid, for example, of oxygen in blood. Origin: L. Tensio, Gr. Tonos (13 Jan 1998) |
| tension curve | The direction of the trabeculae in cancellous bone tissue adapted to resist stress. (05 Mar 2000) |
| tension headache | <neurology> A benign form of headache that results from the painful spasm (muscle tightness) and inflammation of muscles of the head and neck. Tension headache is one of the most common forms of headache. Spasm and contraction of the head and neck muscles may occur in response to fatigue, overuse, eye strain, excessive smoking, stress, anxiety or depression. Sleeping in an abnormal position or prolonged work involving immobilisation of the neck in one position (typing, computers, etc.) are considered common triggers. Exercising and stretching the muscles of the head and neck can reduce the occurrence of muscle tension headaches. (13 Jan 1998) |
