| anxiety tension state | A milder form of an anxiety disorder. See: anxiety disorders. (05 Mar 2000) |

| arterial tension | The pressure of the blood within an artery, the arterial pressure. Also called the intra-arterial pressure. (12 Dec 1998) |
| passive length-tension curve | The relationship between passive tension and preload (rest length) for a muscle at rest. (05 Mar 2000) |
| cervical tension syndrome | <syndrome> A clinical complex of pain, tenderness, tight neck musculature, vasomotor instability, and ill-defined symptoms such as dizziness and blurred vision as the result of trauma to the neck. Also variously termed occipital or suboccipital neuralgia or neuritis; cervical tension syndrome; cervical myospasm, myositis, or fibrositis. Synonym: cervical fibrositis, cervical tension syndrome. (05 Mar 2000) |
| muscle tension headache | 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. (27 Sep 1997) |
| premenstrual tension | <syndrome> A combination of emotional, physical, psychological, and mood disturbances that occur after ovulation and normally end with the onset of the menstrual flow. (12 Dec 1998) |
| premenstrual tension syndrome | <syndrome> A combination of emotional, physical, psychological, and mood disturbances that occur after ovulation and normally end with the onset of the menstrual flow. (12 Dec 1998) |
| surface tension | The expression of intermolecular attraction at the surface of a liquid, in contact with air or another gas, a solid, or another immiscible liquid, tending to pull the molecules of the liquid inward from the surface; dimensional formula: mt-2. (05 Mar 2000) |
| surface tension theory of narcosis | That substances which lower the surface tension of water pass more readily into the cell and cause narcosis by decreasing metabolism. (05 Mar 2000) |
| interfacial surface tension | The tension or resistance to separation possessed by the film of liquid between two well-adapted surfaces, as of the thin film of saliva between the denture base and the tissues. (05 Mar 2000) |
| intraocular tension | The pressure within the eye. See: Intraocular pressure. (12 Dec 1998) |
| intravenous tension | The pressure of the blood within a vein, the venous pressure. (12 Dec 1998) |
| isometric tension | Tension generated in a muscle without contraction occurring: cross bridges are being re formed with the same site on the thin filament and the tension (in striated muscle) is proportional to the overlap between thick and thin filaments. (18 Nov 1997) |
| ocular tension | Resistance of the tunics of the eye to deformation; it can be estimated digitally or measured by means of a tonometer. (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) |
