Tractatus anatomico-physiologicus de quinto pare nervorum cerebri.

Meckel’s graduation thesis contains the first really detailed account of the trigeminal nerve’s distribution (along with a meticulous treatment of the earlier literature), and in it he describes for the first time the pterygopalatine ganglion (Meckel’s ganglion) and the dural recess (Meckel’s cave) that lodges the trigeminal (Gasser’s) ganglion.
