Fabricius, Johann Christian (sh) and commissura fornicis (medicine)


Fabricius, Johann Christian (sh)




born Jan. 7, 1745, T?ndern, Den.
died March 3, 1808, Kiel

Danish entomologist.

He studied at Uppsala University with Carolus Linnaeus and from 1775 taught not only natural history but also Economics and finance at the University of Kiel. He advanced theories progressive for his time, particularly the view that new species and varieties could arise through hybridization and by environmental influence on anatomical structure and function. His taxonomic research was based on insect mouthparts rather than their wings.


commissura fornicis (medicine)


commissura fornicis


The triangular subcallosal plate of commissural fibres resulting from the converging of the right and left fornix bundles which exchange numerous fibres and which curve back in the contralateral fornix to end in the hippocampus of the opposite side.

Synonym: commissura hippocampi, commissure of fornix, delta fornicis, hippocampal commissure, psalterium, transverse fornix.
