1958 M. J. Moses in Jrnl. Biophysical & Biochem. Cytol. IV. 637/1 The term ‘chromosomal core’ was applied to the axial complex when it was first described... A more precise term would..indicate that the structure is associated specifically with chromosome pairing, and that it is thread-like. Unwieldy though it is, synaptinemal complex is more accurately descriptive.

1969 M. J. Moses in Genetics 61 Suppl. 50 It is proposed that ‘synaptonemal complex’, because it is similar to the original term and has been employed in the literature to refer to the structure in meiotic bivalents, henceforth be used in place of ‘synaptinemal complex’.

1969 M. J. Moses in Genetics 61 Suppl. 50 The synaptonemal complex (SC) is a regularly occurring, coplanar set of parallel strands (usually three), coaxial to meiotic bivalent chromosomes. Presence of this linear complex is prerequisite to, but not alone sufficient for chiasma formation (and hence, crossing-over).

1971 Nature 3 Sept. 48/1 Chromosome synapsis mediated by the synaptonemal complex seems to be non-specific, for it can also pull together non-homologous chromosomes.

1978 Bio Systems 10 111/1 A clear prediction of my phylogeny is that meiotic synaptinemal complex proteins should be homologous in all organisms.
