Morphology

tentorial + sinus

The noun is compositionally built from 'tentorial' (relating to the tentorium) and 'sinus' (a venous channel), so a learner who knows both constituents can infer it denotes a venous channel associated with the tentorium. Although technical, this follows standard anatomical naming patterns (common across languages), making the meaning directly derivable from the parts.

Etymology

Tentorial sinus comes from the image of a 'tent' inside the skull: tentorial refers to a tent-like sheet that covers the back part of the brain and sinus means a hollow 'channel' for blood. So the name shows it is a blood channel next to that tent-like sheet.
