590 GLOSSARY. CELLULAR TISSUE COAGULATION. 



mals, have no nuclei or cytoblasts. The cell- wall is generally made 

 transparent by acetic acid, and if it disappears it may be brought 

 again into view by neutralising the acid by means of potash or 

 soda. The nuclei of some cells, as those of epithelium cells and 

 pigment cells, contain nucleoli, or nucleus corpuscles. 



CELLULAR TISSUE and CELLULAR SUBSTANCE. See Areolar Tissue. 



CELLULOSE, or CELLULINE. The proximate principle composing the 

 basement tissue in vegetable bodies, nearly pure in cotton, linen, 

 and elder-pith. It passes into lignine or woody tissue by becoming 

 encrusted with a deposit lining the cells originally composed of pure 

 celluline. See p. 333. 



CENTRIFUGAL, CENTRIPETAL. Terms applied to nerve-fibres. Cen- 

 trifugal, passing from the nervous centres, the same as efferent ; 

 centripetal, passing to the nerve-centres, the same as afferent. 



CEREALIA. The grasses, the fruit of which affords bread, or supplies 

 the place of bread. 



CHEST. See Abdomen. 



CHILOGRAMME, CHILOMETRE. See Weights and Measures. 



CHLORINE. A simple gaseous body, known in nature only in com- 

 bination with metallic substances ; as with sodium in common salt, 

 the chloride of sodium. Its compounds with metallic bodies are 

 known as chlorides. 



CHOLESTERINE. A proximate principle of the animal body found in 

 bile, in blood, in the brain, in the yolk of egg. It is a non-azot- 

 ised body. 



CHONDRINE. A proximate principle'of the animal body allied to gel- 

 atine : both are azotised principles ; they are not, however, held 

 to be flesh-formers nay, it is doubtful if they be at all nutritive. 

 Chondrine exists in the cornea of the eye and in the permanent 

 cartilages. See p. 309. 



CHYLE, CHYME. Chyle is the liquid derived from the digested food 

 of the alimentary canal as taken up by the lacteals. Perfect chyle 

 is that obtained from the thoracic duct after it has been subjected 

 to the action of the mesenteric glands. Chyme is the pultaceous 

 mass which the stomach delivers up to the duodenum or highest 

 part of the intestines after the food has undergone ventricular or 

 stomach digestion that mass is not homogeneous, yet more or less so. 



CHYLOPOETIC, CHYLOPOIETIC. Applied to the organs concerned in 

 digestion the stomach, intestines, omenta, and mesentery the 

 assistant chylopoetic viscera being the liver, pancreas, and spleen. 



CILIA, CILIARY MOTION. Cilia are minute processes of the epitheli- 

 um in certain parts of the body, no more than the 1 -5000th part 

 of an inch in length, which, during life, and for a short time after 

 death, are in incessant motion. 



COAGULATION. A change on a fluid like that produced by rennet on 

 milk.
