| medullary chemoreceptor | The chemoreceptor's in or near the ventrolateral surface of the medulla that are stimulated by local acidity. (05 Mar 2000) |
| chemoreceptor | A receptor adapted for excitation by chemical substances, for example, olfactory and gustatory receptors or a sense organ, as the carotid body or the aortic (supracardial) bodies, which is sensitive to chemical changes in the blood stream, especially reduced oxygen content and reflexly increases both respiration and blood pressure. See: receptor. (18 Nov 1997) |
| chemoreceptor tumour | Aortic body, carotid body, chemoreceptor, or glomus jugulare tumour; nonchromaffin paraganglioma; receptoma; a relatively rare, usually benign neoplasm originating in the chemoreceptor tissue of the carotid body, glomus jugulare, and aortic bodies; consisting histologically of rounded or ovoid hyperchromatic cells that tend to be grouped in an alveolus-like pattern within a scant to moderate amount of fibrous stroma and a few large thin-walled vascular channels. Compare: paraganglioma. Synonym: aortic body tumour, carotid body tumour, chemoreceptor tumour, glomus jugulare tumour, nonchromaffin paraganglioma. Origin: chemo-+ G. Dektes, receiver, fr. Dechomai, to receive, + -oma, tumour (05 Mar 2000) |
| peripheral chemoreceptor | The chemoreceptor's in the carotid and aortic bodies that are stimulated by chemical changes in the composition of the blood such as hypoxia. (05 Mar 2000) |

| trigger | 1. A catch to hold the wheel of a carriage on a declivity. 2., the part of a lock which is moved by the finger to release the cock and discharge the piece. <zoology> Trigger fish, a large plectognath fish (Balistes Carolinensis or B. Capriscus) common on the southern coast of the United States, and valued as a food fish in some localities. Its rough skin is used for scouring and polishing in the place of sandpaper. Synonym: leather jacket, and turbot. Origin: For older tricker, from D. Trekker, fr. Trekken to draw, pull. See Trick. Source: Websters Dictionary (01 Mar 1998) |
| trigger area | A specific point or area where, if stimulated by touch, pain, or pressure, a painful response will be induced. Synonym: dolorogenic zone, trigger area, trigger zone. (05 Mar 2000) |
| trigger finger | An affection in which the movement of the finger is arrested for a moment in flexion or extension and then continues with a jerk. Synonym: jerk finger, lock finger, snap finger, spring finger, stuck finger. (05 Mar 2000) |
| trigger point | A specific point or area where, if stimulated by touch, pain, or pressure, a painful response will be induced. Synonym: dolorogenic zone, trigger area, trigger zone. (05 Mar 2000) |
| trigger protein | <protein> See U protein. (18 Nov 1997) |
| androgenic zone | A transient adrenocortical zone present in some rodents at birth, most notably in mice, situated between the zona reticularis and the adrenal medulla; it degenerates in males with the secretion at puberty and in females during their first pregnancy; it slowly enlarges in unmated females after puberty and does not degenerate until middle age; the X zone appears to secrete no hormone. Synonym: androgenic zone. Misnomer for the foetal adrenal cortex of primates. Synonym: foetal reticularis. (05 Mar 2000) |
| arcuate zone | The inner third of the basilar membrane of the cochlear duct extending from the tympanic lip of the osseous spiral lamina to the outer pillar cell of the spiral organ (of Corti). Synonym: zona arcuata, zona tecta. (05 Mar 2000) |
| Barnes' zone | The lower fourth of the pregnant uterus, attachment of the placenta to any part of which may cause dangerous haemorrhage. Synonym: cervical zone. (05 Mar 2000) |
| buffer zone | <ecology> An area of land separating two distinct land uses that acts to soften or mitigate the effects of one land use on the other. (09 Oct 1997) |
| chemoreceptor trigger zone |
ABBR: CTZ. A zone in the medulla that is sensitive to certain chemical stimuli. Stimulation of this zone may produce nausea.
