Innervation of the tentorium cerebelli identified using Sihler's stain. (a) Linear and curved projections of the nervus tentorii with an asymmetrical innervation pattern in the same individual. (b) Separate courses of independent groups of nerve fibres to both the straight and transverse sinuses. (c) Nerve fibres project to both the straight and transverse sinuses as a consequence of significant pruning. (d) Nerve fibres projecting to the straight sinus changed their directions to the transverse sinus with arborization to both the straight and transverse sinuses. (e) There were few nerve fibres within the territory of the tentorium cerebelli. A, anterior; L, left; P, posterior; R, right; black arrows, locations of nerve fibres with acutely curved projections; black and white triangles, nerve fibres in general.
