| statocyte | <plant biology> A root tip cell containing one or more statoliths, involved in the detection of gravity in geotropism. (20 Mar 1998) |
|---|---|
| statokinetic | Pertaining to statokinetics. (05 Mar 2000) |
| statokinetic reflex | A reflex which, through stimulation of the receptors in the neck muscles and saemicircular canals, brings about movements of the limbs and eyes appropriate to a given movement of the head in space. (05 Mar 2000) |
| statokinetics | The adjustment made by the body in motion to maintain stable equilibrium. Origin: G. Statos, standing, + kinesis, movement (05 Mar 2000) |
| statolith | 1. <botany> A type of amyloplast found in root tip cells of higher plants. It can sediment within the cell under the influence of gravity and is thought to be involved in the detection of gravity in geotropism. 2. <zoology> A sand grain or a structure of calcium carbonate or other hard secreted substance, found in the cavity of a statocyst. It stimulates sensory cells lining the cavity with which it comes in contact under the influence of gravity. (20 Mar 1998) |
| statoliths | Crystalline particles of calcium carbonate and a protein adhering to the gelatinous membrane of the maculae of the utricle and saccule. Synonym: statoconia, ear crystals, otoconia, otoliths, otolites, sagitta. Origin: G. Statos, standing, + lithos, stone (05 Mar 2000) |
| statometer | Synonym: exophthalmometer. Origin: G. Statos, standing, + metron, measure (05 Mar 2000) |
| statosphere | Alternative (rare) name for centrosome. (18 Nov 1997) |
| statotonic reflexes | Reflex's in which utricular receptors in the vestibular apparatus sense changes in the head's position in space in terms of linear acceleration and the earth's gravitational field while receptors in the neck muscles sense changes in the position of the head relative to the trunk; input from these receptors reflexly controls the tone of the limb muscles to maintain or regain the desired posture. Synonym: attitudinal reflexes. (05 Mar 2000) |
| statua | A statue. "They spake not a word; But, like dumb statuas or breathing stones, Gazed each on other." (Shak) Origin: L. Source: Websters Dictionary (01 Mar 1998) |
| stature | The height of a person. Origin: L. Statura, fr. Statuo, pp. Statutus, to cause to stand (05 Mar 2000) |
| status | State or condition. (18 Nov 1997) |
| status anginosus | Prolonged angina pectoris refractory to treatment. (05 Mar 2000) |
| status arthriticus | An obsolete term for gouty diathesis or predisposition. (05 Mar 2000) |
| status asthmaticus | A severe asthma attack where there is profound and intractable bronchospasm. (27 Sep 1997) |
