ANATOMICAL NOMENCLATURE [BNAJ FOR 



THE NERVOUS SYSTEM AND 



SENSE ORGANS. 



Much confusion has resulted in the anatomical literature from 

 the use of various names for the same organ or structure. To 

 obviate this it became necessary that scientists should agree 

 upon some one set of terms. To this end the Basel Commission 

 of Anatomists was convened. After the expenditure of much 

 care and labor, the commission selected a nomenclature for the 

 gross anatomy of the entire body. This nomenclature is now 

 being adopted by anatomists generally. It is commonly known 

 as the [BNAJ which is an abbreviation for ''Die in Basel ange- 

 nommenen nomina anatomica." 



It was necessary that the names be of uniform construction 

 and in a language which would most easily permit of their uni- 

 versal adoption. The Latin was chosen, therefore, both because 

 an acquaintance with that language is more nearly universal than 

 with others, and because of the prevalence of Latin in the ana- 

 tomical nomenclature already existing. 



That part of the [BNAJ which pertains to the nervous 

 system and sense organs is given here, with the hope that it will 

 be of convenience to both instructors and students. If not 

 already familiar with the nomenclature, one will certainly have 

 frequent need to refer to a classified list of the terms. In the 

 literature it will be found that the [BNAJ is becoming more 

 and more used, while the older or more conservative text-books 

 do not use the nomenclature strictly, nor do they contain a list 

 of the terms for reference. 



The following list of terms is taken from that part of the 

 [BNAJ contained in Professor His's paper on anatomical nomen- 

 clature.'
