Embryonic anastomosis between hypoglossal nerves. Anatomical Science International. 2009 Dec;84(4):293-7.1447-073X10.1007/s12565-009-0037-yhttps://hdl.handle.net/20.500.14352/97545This article presents two cases of anastomosis of hypoglossal nerves in the suprahyoid region in human embryos of CR length 10.75 and 17.5 mm. This variation was studied in two human specimens at this stage of development and compared with the normal arrangement of the hypoglossal nerves in embryos at the same stage. The anastomotic branches were of similar caliber to the main trunks. In both cases the anastomosis was located dorsal to the origin of the geniohyoid muscles and caudal to the genioglossus muscles, lying transversally over the cranial face of the body of the hyoid bone anlage. The anastomosis formed a suprahyoid nerve chiasm on the midline in the embryo of 10.75 mm CR length.engjournal articlehttps://doi.org/10.1007/s12565-009-0037-y19330282https://pubmed.ncbi.nlm.nih.gov/19330282/restricted access611611.013Hypoglossal nerveEmbryologyCranial nerveCiencias Biomédicas32 Ciencias Médicas
