CORPUSCLE 



332 



CORROSION 



are about ^W in. in diameter and 725577 in. thick. 

 They consist of a colorless stroma (paraglobulin, 

 cholesterin, lecithin, and neurin) infiltrated with color- 

 ing-matter (hemoglobin). The white or colorless 

 corpuscles are flattened, binucleated or trinucleated 

 cells, about -^sms * n - m diameter, and exist in the 

 ratio of I : 400 compared with red corpuscles. They 

 possess contractile power, alter their shape readily, 

 and in general appearance closely resemble amebse. 

 They are most numerous in venous blood. The color- 

 less corpuscles are variously designated as eosinophile , 

 basophile, neutrophile , mononuclear, polynuclear, lym- 

 phocytes, transitional, large, small, etc. C. of Donne. 

 See Colostrum-corpuscles. C, Eichhorst's, a special 

 form of microcyte in the blood of those suffering from 

 pernicious anemia. C, Gluge's, a variety of large 

 cells containing fat-drops, myelin, or detritus. They 

 are called also Compound Granule- Cells and Inflamma-

I, I, 1. Nerve-tubule. 2, 

 2, 2. Its medullary sub- 

 stance. 3, 3, 3 Nuclei 

 of the sheath of Schwann. 

 4. Granular substance 

 occupying the center of 

 the corpuscle and the 

 contained nuclei. 



Corpuscle of Pacini. 

 1. Base, or proximal extremity. 



2. Summit, or distal extremity. 



3. Capsules displaying nuclei. 



4. 4. Attachment of capsules to 

 sheath of nerve-tubule. 5. Cavity 

 of corpuscle. 6 Nerve-tubule. 

 7, 7. Nerve-tubule successively 

 losing its medullary sheath and 

 neurilemma. 8. Enlargement in

tory Corpuscles. C. of Krause, the spherical or 

 ovoid corpuscles occurring at the ends of the nerve- 

 tubules that emerge from a nerve-plexus. They occur 

 in the conjunctiva, the edges of the lips, and various 

 mucous and glandular surfaces. C, Malpighian, a 

 name applied to the splenic corpuscles, and to the 

 Malpighian bodies. C. of Neumann, the nucleated 

 colored corpuscles of the blood seen after repeated 

 hemorrhages. C, Norris's Invisible, colorless, 

 transparent, biconcave discs of the same size as the 

 red ones, invisible in the serum because their color and 

 refractive index are the same as those of the liquor san- 

 guinis; they are believed by Norris to exist normally 

 in the blood. They are probably red corpuscles that 

 have lost their hemoglobin. C, Pacinian, certain 

 small corpuscles occurring in the subcutaneous cellular 

 tissue of the fingers and toes. C. of Purkinje, a bone- 

 cell. See Purkinje. C, Shadow. Sec Shadow. C,

 fibers. C. of v. Troltsch, a name formerly given to 

 a series of lymph-channels between the two layers of 

 the lamina propria of the ear. They 

 are spindle-shaped on longitudinal 

 section and stellate on transverse 

 section, and are lined with endothe- 

 lium. C, Valentin's, the small, 

 roundish amyloid bodies found in 

 nerve-substance. C, Weber's, the 

 sinus pocularis.

 nalia, in biology, the marginal sense- 

 organs of Medusce. 



Corpuscular {kor-pus'-ku-lar) [cor- 

 pusculum, a little body]. Relating 

 to or of the nature of a corpuscle. 



Corpusculation {kor-pus-ku-la' -shun) 

 [corpusculum, a corpuscle]. A con- 

 dition in which the corpuscles of the 

 blood have undergone hyperplasia, 

 being larger and more numerous than 

 normally. 



Corpusculous (kor-pus'-ku-lus) [cor- 

 pusculum, a corpuscle]. Corpuscular. 



Corpusculum {kor-pus'-ku-lum) [L. : 

 pi. , Corpuscula]. A corpuscle. 



Correctant, or Corrective {kor-ek'- 



tant or kor-ek'-thi) \_corrigere, to correct]. I. Having 

 the power to correct or to modify favorably. 2. A 

 substance used to modify or make more pleasant the 

 action of a purgative or other remedy. 



Correction (kor-ek' '-shun) [correctus ; corrigere, to 

 amend]. The rectification of any abnormality 

 refractive or muscular defect) , or of any undesirable 

 quality (as in a medicine).

Corrigan's Button. A cautery-iron. It consists of a 

 button of iron, ^ inch in diameter by % inch thick, 

 fastened in a wooden handle by a rod 2 inches long. 

 C. Cautery. Same as C. Button. C. Disease. See 

 Diseases, Table of. C. Line. See Signs and I 

 toms, Table of, and Litie. C. Pulse, water-hammer 

 pulse. The jerking pulse of aortic regurgitation. 

 The volume of the pulse is large, owing to the hyper 

 trophy and dilatation of the left ventricle ; hence tl 

 a sudden expansion of the arteries. The regurgitation 

 of the blood, however, as suddenly empties the artery. 

 and the pulse-wave subsides rapidly. The peculiarities 

 of the radial pulse may usually be intensified h) 

 ing the hand. It is also called the collapsing. spe, 

 reading, locomotive, kicking, and shuttle pulse

 preparation, one in which the vessels, ducts, 01
