Dorsum

In Linguistics , a Dorsal Consonant refers to hard sounds utilizing the tongue on the back of the mouth, such as Palatal , Velar , and Uvular consonants.

In Neurology , dorsal is an outdated term for the Medial Longitudinal Fasciculus in the Neural Arch . In 1846 Neurologist Benedict Stilling first referred to what is now known as the Medial Longitudinal Fasciculus as ''acusticus'', followed by Theodor Meynert in 1872 calling it ''posterior''. But in 1891, Heinrich Schutz chose the name ''dorsal'' to describe the longitudinal bundle, "for brevity's sake". This name stuck despite other authors attempting further renaming ( Ramon Y Cajal 's ''periependymal'' in 1904, Theodor Ziehens 's ''nubecula dorsalis'' in 1913). But finally, it was Wilhelm His, Sr who changed the name to ''medial'' for the sake of the Basle Nomenclature to end the confusion.

ETYMOLOGY

The use of ''dorsal'' meaning "the back of an animal or fish" dates from the , meaning a double-sided knife.
