| Cheatle slit | A longitudinal incision into the antimesenteric border of the small intestine, which when closed transversely creates a larger lumen than would be possible by simple end-to-end anastomosis; currently modified to include longitudinal incisions into the cut ends of the transected small intestine or other tubular structures, allowing a wide caliber elliptical anastomosis to be performed.

| check ligaments of eyeball | <anatomy> Medial and lateral, expansions of the sheaths of the medial and lateral rectus muscles of the eyeball which are attached, respectively, to the lacrimal bone and to the orbital tubercle of the zygomatic bone; they serve to prevent overaction of these muscles. (05 Mar 2000) |
| check ligaments of odontoid | One of a pair of short stout bands that extends from the side of the dens of the axis to the tubercle on the medial aspect of the occipital condyle. Synonym: check ligaments of odontoid. Synonym: alar folds. (05 Mar 2000) |
| checkbite | A record of the positional relationship of the teeth or jaws to each other, recorded by placing a plastic material which hardens (such as plaster of Paris, wax, etc.) between the occlusal surfaces of the rims or teeth; the hardened material serves as the record; it may be registered in centric or eccentric positions, as (05 Mar 2000) |
| checkerberry oil | Aromatic methyl ester of salicylic acid, produced synthetically or distilled from Gaultheria procumbens (family Ericaceae) or from Betula lenta (family Betulaceae). Used as a component of liniments, used externally and internally for the treatment of various forms of rheumatismit produces heat when rubbed into the skin (counterirritant). Synonym: checkerberry oil, gaultheria oil, sweet birch oil, wintergreen oil. (05 Mar 2000) |
| checkerboard assay | <procedure> Variant of the Boyden chamber assay for leucocyte chemotaxis introduced by Zigmond. By testing different concentrations of putative chemotactic factor in nongradient conditions, it is possible to calculate the enhancement of movement expected due simply to chemokinesis and to compare this with the distances moved in positive and negative gradients. Good experimental design thus allows chemotaxis to be distinguished from chemokinesis. (21 May 1997) |

| Chediak-Higashi disease | <syndrome> An autosomal recessive disorder characterised by the presence of giant lysosomal vesicles in phagocytes and in consequence poor bactericidal function due to deficient secretion of myeloperoxidase by lysosomes. There is some perturbation of microtubule dynamics. There are abnormalities of granulation and nuclear structure of all types of leukocytes with malformation of peroxidase-positive granules, cytoplasmic inclusions, and Dohle bodies, often with hepatosplenomegaly, lymphadenopathy, anaemia, thrombocytopenia, roentgenologic changes of bones, lungs and heart, skin and psychomotor abnormalities, and susceptibility to infection. The condition usually results in death in childhood, before the age of 10. Reported from humans, albino Hereford cattle, mink, beige mice and killer whale. Compare: chronic granulomatous disease. Inheritance: autosomal recessive. Synonym: Beguez Cesar disease, Chediak-Higashi disease, Chediak-Steinbrinck-Higashi anomaly. (21 May 1997) |
