TETRADVXAMOUS 



Testis {tes'-tis) [L.]. I. See Testes. 2. Any organ 

 fancied to have the shape of a testicle. T., Caput, 

 the epididymis. T. cerebri, testis of the brain, the 

 postgeminum ; either of the posterior pair of the 

 corpora quadrigemina. 

 Testitis {tes-ti'-tis). See Orchitis. 

 Testudo (tes-tif-do) [L., a tortoise-shell]. Afigure-of 

 eight bandage about an articulation, the turns crossing 

 on the flexor surface and the spirals overlapping, so 

 over the extensor surface of the joint. 

 Testule [test' -ill) [testa, a shell]. In biology, the frus- 



tule, or silicious skeleton, of a diatom. 

 Tetanic tet-an'-ik) [reravoq, tetanus]. Pertaining to 



tetanus. 

 Tetaniform {tef -an-iform) [reravoq, tetanus; forma, 



form]. Resembling tetanus. 

 Tetanigenous {tet - an - ij '- en - us) [reravoq, tetanus ; 



. to produce]. Productive of tetanus. 

 Tetanilla {tet-an-if -ah) [reravoq, tetanus]. A form of 

 tetanic spasm affecting the lingers and toes. It is 

 observed mainly among children, and is a concomitant 

 of rachitis. 

 'etanin {tef -an- in) [reravoq, tetanus], C^H^XjOj. A 

 toxin present in the blood in tetanus ; a ptomain ob- 

 tained by cultivating tetanus-microbes in beef-broth. 

 It has been obtained from the amputated arm of a 

 tetanus-patient by Brieger, who thus demonstrated the 

 presence of tetanin in tetanus-patients during life. 

 Nevertheless, it has not been found in the brain and 

 nerve-tissue of persons dead from tetanus. The base 

 produces the characteristic symptoms of tetanus, 

 though probably not all, as three other toxins, in- 

 cluding spasmotoxin, occur with tetanin in cultures of 



•tanus-microbe. See Ptomains, Table of. 

 etanium {tet-an' '-e-um). Synonym of Strychnin. 

 etanization {tet - an - iz - a' - shun) [reravoc, tetanus]. 

 The production of tetanus, or of tetanic spasms. The 

 :tion of a protracted contraction in a nerve by an 

 ' electric current. 



etano-cannabin {tef '-an-o-kan 1 '-ab-in) [reravoq, tet- 

 xntiabis]. A basic substance found in some 

 samples of cannabis, or hemp. Its action on the 

 system resembles that of strychnin. Unof. 

 2:anoid [tef -an- oil) [reravoq, tetanus ; elSoc, resem- 

 blance]. Resembling tetanus. 



itanomotor (tet-an-o-mo'-tor) [reravoq, tetanus ; motor, 

 I a mover]. An instrument (usually a rapidly vibrating 

 'hammer) for stimulating a nerve mechanically. 

 Hanotoxin {tet-ati-o-toks' -in) [reravoq, tetanus ; ro^in- 

 poison], C-lI n X. A poisonous ptomain obtained 

 by Brieger as one of the products of the culture of 

 he tetanus-microbe. It is tetanizing in its action, 

 lucing first tremor, then paralysis and violent con- 

 vulsions. See Ptomains, Table of. 

 tanus tef -an -us) [reravoq, reiveiv, to stretch]. A 

 -modic and continuous contraction of muscles, 

 pausing rigidity of the parts to which they are attached, 

 tee Trismus, Opisthotonos, Emprosthotonos, Pleuros- 

 Brieger has isolated four toxic ptomain-sub- 

 tances from cultivations of so-called tetanus-bacilli : 

 Tetanin, which produced symptoms of tetanus (in 

 nice); Tetatoxin, which caused tremor, paralysis, and 

 onvulsions ; Muriate of Toxin, which produced tetanus 

 nd salivation ; Spasmotoxin, which prostrated quickly, 

 nth clonic and tonic spasms. T., Acoustic. See 

 houstic. T., Cephalic, T., Cerebral, T., Hydro- 

 'hobic, T.. Kopf-, a special form of tetanus that has 

 ametimes been observed to follow injuries of the 

 specially those in the neighborhood of the 

 >ro\v. Trismus and facial paralysis occur upon 

 ie side of the injury. There is dysphagia, and death 

 equently results. T. dolorificus. Synonym of 



Cramp. T., Extensor, a form of tetanus in which 

 the extensors act more powerfully than the flexors. 

 T., Hydrophobic. See T, Cerebral. T., imita- 

 tive, hysteria which simulates tetanus. T. infantum. 

 See T. neonatorum. T., Localized, tetanic spasm 

 of a part. T., Post-operative, that following opera- 

 tion. Chvostek's Sign, a diagnostic and pathognomonic 

 sign of post-operative tetany. A slight tap upon the 

 side of the face, over the point where the facial nerve 

 emerges from the parotid, suffices to call forth a sud- 

 den spasm of that side of the face. T., Ritter's, 

 the series of contractions, or apparent tetanus, observed 

 on the opening or interrupting of an electric current 

 which has been passing through the nerve for some 

 time. Opening tetanus. T., Toxic, tetanus pro- 

 duced by an overdose of nux vomica or its alkaloids. 

 T., Traumatic, tetanus following an injury. 



Tetany [t,t'-an-e) [reravoq, tetanus]. A tonic spasm 

 of the extremities occurring chiefly in rickety infants 

 and lasting a variable time. The ringers, hands, and 

 wrists are the portions mainly affected. It occasionally 

 occurs in nursing women also. See Tetanilla. T., 

 Epidemic, T, Rheumatic ; a form occurring over 

 large portions of Europe, especially in the winter 

 season. It is acute, lasting only two or three weeks, 

 and rarely proving fatal. T., Gutturo-, a stammering 

 due to tetanoid spasm of the laryngeal muscles. 

 T., Rheumatic. See T, Epidemic.
