For the vertebrate brain structure, see [[Tentorium cerebelli]] The '''tentorium''' (plural '''tentoria''') is a term used to refer to the framework of internal supports (a false [[endoskeleton]]) within an [[arthropod]] head. The tentorium is formed by ingrowths of the [[exoskeleton]], called [[apophysis|apophyses]], which fuse in various ways to provide rigid support for the muscles of the head (particularly those associated with the mouthparts) and additional protection for the [[brain]] and other neural structures. The arthropod head is therefore generally the part of the body that is least prone to distortion. {{arthropod-stub}} [[Category:Animal anatomy]]
