Libelle of note

Several Sinus durae matris have been added: 1) Sinus tentorii (Tentorial sinus; see Matsushima M, Suzuki SO, Fukui M, et al. 1989 Microsurgical anatomy of the tentorial sinuses. J Neurosurg 71:923-928); 2) A variable Sinus occipitalis obliquus (Oblique occipital sinus; see Tubbs RS, Bosmia An, Shoja MM, et al. 2011 The oblique occipital sinus: A review of anatomy and imaging characteristics. Surg Radiol Anat 33:747-749); 3) A variable Plexus venosus falcis (Venous plexus of falx; see Tubbs RS, Loukas M, Shoja MM, et al. 2007 Anatomy of the falcine venous plexus. J Neurosurg 107:155-157); 4) A variabe Sinus intercavernosus inferior (Inferior intercavernous sinus; see Tubbs RS, Griessenauer C, Loukas M, Cohen-Gadol A 2014 Circular sinus: An anatomical study with neurosurgical and neurointerventional applications. World Neurosurg 82:475-478).

New term; the Venulae aquosae ('Wasservenen') were described by Ascher KW (1942) Am J Ophthalmol 25:31. They collect the Humor aquosus from the Sinus venosus sclerae, and drain into the Venae episclerales.

The Dentes subiculi (Gyri of Andreas Retzius) were described by Retzius (1896) for the Caudal part of CA1 at the Hippocampal tail; the term Gyri subspleniales (Subsplenial gyri) indicate their position. Deep to the Gyri andreae retzii, two obliquely oriented small gyri are found (Duvernoy 1998; Insausti and Amaral 2012): 1) a medial gyrus: the Fasciola cinerea, which forms the visible part of the Dentate gyrus as descibed by Giacomini (1884) and Klingler (1948); and 2) a lateral gyrus: Gyrus fasciolaris (Fasciolar gyrus), corresponding to the caudal end of the CA3 field.

The Arcus labiorum inferior is an arterial anastomosis between both superior labial arteries, located in the musculus orbicularis oris of the lower lip (Kachlik et al. 2021 Bosn J Basic Med Sci 21:208-220).

The Arcus labiorum superior is an arterial anastomosis between both superior labial arteries, located in the musculus orbicularis oris of the upper lip (Kachlik et al. 2021 Bosn J Basic Med Sci 21:208-220).
