Morphology

straight + sinus

The noun is directly compositional: 'straight' (having no bend) + 'sinus' (a venous/vascular channel) yields the understandable sense 'a straight venous channel.' While full anatomical details (unpaired, location in the dura, specific tributaries) require specialist knowledge, the basic meaning is transparently derivable from the constituents.

Etymology

Straight sinus is a medical name that gives a clear picture: straight shows its mostly straight path and sinus is an old word for a 'channel' that carries 'blood' in the brain, so the term means a straight blood channel that helps drain blood from the brain.
