1897 M. Foster Text Bk. Physiol. (ed. 7) III. i. 928 It will be convenient to distinguish by a separate name between the processes whether axon or dendrite, and the part from which these processes start, namely the body of the cell surrounding the nucleus; the latter might be called the perikaryon.

1925 Proc. Royal Soc. 1924–5 B. 97 519 The term ‘motor-unit’ includes..the whole axon of the motoneurone from its hillock in the perikaryon down to its terminals in the muscle.

1961 New Scientist 12 Oct. 117/3 In the invertebrates the [nerve] fibre is not so long and does not usually end on a blood vessel; the perikaryon instead provides more or less all the available storage space.

1995 C. Nielsen Animal Evol. xvii. 129 In many forms [of polychaete] the cords sink in from the epithelium during ontogeny..and the perikarya become arranged in paired ganglia.
