Abbreviations: CNA, canalis nervi abducentis. FAC, foramen anterior canalis carotici interni. FNT, foramen nervi trigemini. PIP, processus inferior parietalis. RBS, rostrum basisphenoidale. order from posterior to anterior. The crista pterygoidea enters the ex- treme ventral margin of the anterior quarter of the lateral cranial wall. This wall is penetrated by a series of foramina, mostly for the passage of all but the four most anterior cranial nerves (the canal for the abducens is more ventral and has already been mentioned). Posteroventrally the hypoglossal nerve exits through two small foramina nervi hypoglossi which are surrounded by the exoccipital. Slightly anterodorsal to these,.
