1890 Patten in Q. Jrnl. Microsc. Sci. Aug. 369 Three longitudinal sections, showing successive stages in the formation of a telopore by the invagination of teloblasts.

1899 L. F. Barker Nerv. Syst. viii. 82 The ultimate terminals (telodendrions) of the axones have been carefully and exactly studied.

1907 I. Hardesty in Morris & McMurrich Morris's Treat. Human Anat. (ed. 4) 751 The axone bearing the impulse on approaching its termination loses its sheath and breaks up into its numerous terminal twigs, the final of which are called telodendria.

1949 Blakiston's New Gould Med. Dict. 1030/2 Telodendrion. See telodendron.

1966 C. R. Leeson & T. S. Leeson Histol. x. 178/2 In some cases, the telodendria are so numerous as to surround the neuron on which they terminate in a basket~like arrangement.

1883 Athenæum 29 Dec. 870/3 Four very distinct phases of development in their mandibles, which the author [sc. F. Leuthner] proposed to term ‘priodont’, ‘amphiodont’, ‘mesodont’, and ‘telodont’.

1940 G. R. de Beer in J. S. Huxley New Systematics 381 The mandibles of the males not only vary in relative size, but also in the number and disposition of ‘teeth’ carried on them, to such an extent that five types (‘prionodont’, ‘amphiodont’, ‘telodont’, ‘mesodont’, ‘mesamphiodont’) have been distinguished by coleopterists.

1946 Trans. Amer. Entomol. Soc. 72 164 The largest development.., with slender middle section and reduced number of subapical teeth, becomes the telodont form of Leuthner, or constant phase of Arrow.

1880 F. M. Balfour Treat. Compar. Embryol. I. iii. 90 The ova in which the yolk is especially concentrated at one pole I should propose to call telolecithal.

1888 E. R. Lankester in Nature 29 Mar. 507/1 The classification of animal eggs proposed by Balfour is adopted, viz. alecithal, telolecithal, and centrolecithal.

1940 H. J. Muller in Jrnl. Genetics XL. 2 The reconstructed chromosome cannot continue to be transported..unless it happens to be monocentric and—in Drosophila at least—ditelic, one centromere and two telomeres being necessary and permanent organelles.

1960 L. Picken Organization of Cells vii. 261 Within the nucleus the chromosomes present their telomeres—‘centromeres’ connected to the chromosomes by terminal filaments—to the aspect of the nuclear membrane nearest to the spindle.

1983 Nature 13 Jan. 112/1 Telomeres are very stable as free ends, whereas ends of [DNA] molecules broken in vivo tend to stick together irreversibly.

1917 E. E. Carothers in Jrnl. Morphol. 28 449 The unusual conditions of the chromosomes in this group have made advisable the introduction of..new terms... Telomitic—a term used to indicate terminal fiber attachment.

1934 L. W. Sharp Introd. Cytol. (ed. 3) ix. 116 Supposedly telomitic chromosomes have been shown in some instances to have their attachment region slightly back from the end.

1964 F. O. Schmitt et al. in Proc. National Acad. Sci. U.S.A. 51 494 The term ‘end-chains’ with its terminal connotation has been replaced by the term ‘telopeptides’.

1971 Nature 22 Jan. 242/1 Every third residue in the chain is glycine, except in short ‘non-collagenous’ telopeptides at the N-terminal ends of the chains.

1975 Nature 10 July 125/1 Rabbit anti-collagen serum is primarily directed to terminal (telopeptide) antigenic sites, and not to helical or central sites.

1890 Patten in Q. Jrnl. Microsc. Sci. Aug. 369 A forward continuation of the anterior wall of the terminal pore or telopore.

1877 E. R. Lankester in Q. Jrnl. Microsc. Sci. 17 422 Radial and bilateral symmetry and telostomiate and prostomiate conditions.

1877 E. R. Lankester in Q. Jrnl. Microsc. Sci. 17 423 A specialisation of the ciliated ectoderm at a time when the organism was telostomiate.

1909 E. B. Wilson in Jrnl. Exper. Zool. 6 84 Pyrrochoris shows a close similarity to Tomopteris... This comparison has convinced me that synapsis occurs at the same period in both—whether by parasynapsis (side to side union) or telosynapsis (end to end union). [Note] I have for some years made use of these terms in my lectures on cytology.

1920 W. E. Agar Cytol. ii. 43 Parasyndesis and Telosyndesis. [Note] Called parasynapsis and telosynapsis by cytologists, who employ the term synapsis in the sense in which syndesis is here used.

1945 M. J. D. White Animal Cytol. & Evol. v. 79 The old controversy between adherants of the theory of telosynapsis and those who believed in the alternative viewpoint..is only of historical interest, since ‘parasynapsis’..is now known to be universal.

1912 Jrnl. Exper. Zool. 13 394 Attention may be called to the increasing tendency..to reject, or at least restrict, the theory of parasynapsis.., in favor of a telosynaptic conception.

1929 Jrnl. Genetics 21 47 Digby's interpretation, so much quoted in support of the telosynaptic view.., is due to a misunderstanding of the essential features of meiosis.

1910 Ann. Bot. 24 752 Whether these univalent strands join with their homologous pairs telosynaptically or parasynaptically, or by any other intermediate method between these two extremes, resolves itself merely into a question of non-essential detail.

1926 Genetics 11 274 The third element is joined telosynaptically to the other two chromosomes.

1920 L. Doncaster Introd. Study Cytol. v. 68 The end-to-end union [of chromosomes] (formerly supposed to be frequent or universal) is telosyndesis (or telosynapsis).
