Cerebral hemispheres ( Tiedemann, 1816 ) : Synonym for endbrain (Kuhlenbeck, 1927). It was used in this way by Teidemann (see 1826 translation, p. 15), and more recently by for example Strong & Elwyn (1943, pp. 13-16), Carpenter (1976, p. 21), Williams & Warwick (1980, p. 864), and Nauta & Feirtag (1986, p. 43), but has also been defined in many other ways.

Spinal nerve roots ( srt ; Tiedemann, 1816 ) : In general, each of the spinal nerves (Camper, 1760) has a peripheral dorsal root and ventral root between the surface of the spinal cord (Galen, c162-c166) and the plane where they merge into a composite spinal nerve trunk. The spinal nerve roots were discovered in macrodissected adult humans by Coiter (1572, see translation of 1995, p. 115); they were named such by Tiedemann (1816, see translation of 1826, p. 126).
