ioi EXPLANATORY NOTES TO CERTAIN OF THE TERMS 



Explanatory Notes to Certain of the Terms. 



While there can be no doubt as to the exact meaning of the majority of the 

 names in the list, there are some names included which hitherto have been used 

 with different meanings in different text-books, and here and there a new term, 

 not to be found in any of the text-books, is included. 



To indicate the exact meaning of these, Professor His, with the approval of 

 the editing committee, wrote a series of brief explanatory notes. Thus, for 

 example, the designations regarding the position and direction of parts of the 

 body are explained, transfer sails meaning across the axis of the body, transversus 

 across the axis of the organ concerned. The word inlermedius is used for the 

 position midway between medialis and later alls in order to avoid the juxta- 

 position of words sounding so much alike as medius and medialis; between 

 anterior and posterior or between externus and internus the adjective medius is 

 retained. The notes contain a long discussion on the nomenclature of " glands" 

 and "lymphglands." In connection with general terms it is noted that discus 

 means " disc," while meniscus means " crescent." In the osteological notes 

 the terms glabella, infundibulum ethmoidale, and sulci paraglenoidales are, 

 among others, clearly denned. Comments on the Pars lacrimalis m. orbicularis 

 or Horner's muscle, the M. quadratus labii superioris (the old " Mm. levator labii 

 superioris proprius, levator labii superioris alaeque nasi and zygomaticus minor" 

 combined), theRaphe pterygomandibularis, the Fasciculi transversi of the palmar 

 aponeurosis, the Scalenus minimus, the Ligamentum jundijorme penis, the Falx 

 inguinalis (the old " conjoined " tendon or Henle's ligament), and the Ligamen- 

 tum inter joveolare (Hesselbach's ligament) are made in connection with myology. 



Some rather important notes accompany the splanchnological terms. Cer- 

 tain new terms have been adopted in the tonsillar region, partly on embryological 

 grounds. The Recessus pharyngeus of Rosenmueller is exactly denned, as 

 is also the Bursa pharyngeus (p. 128). In connection with the Pars analis 

 recti attention is called to the excellent description given by the French anato- 

 mists, Sappey and Testut. A number of the names for parts of the nose and 

 larynx have been drawn from the special literature. The less familiar of these 

 in the nose Limen nasi, atrium meatus medii, agger nasi, Sulcus olfactorius, 

 Recessus sphenoethmoidalis, meatus naso pharyngeus, Meatus nasi communis, 

 Processus sphenoidalis septi cartilaginei are explained. In the larynx marked 

 precision has been arrived at and a great advance in nomenclature has been 

 made. The old terms Glottis vera and Glottis spuria have been done away
