Morphology
The term is a literal adjective–noun composition: 'transverse' (crosswise) modifies 'sinus' (a venous channel), so the meaning — a venous channel running crosswise in the head — is directly derivable from the parts. It is technical medical vocabulary but, given knowledge of both constituent senses, a B1 learner would be able to infer the basic meaning.
Etymology
Transverse sinus comes from a simple picture: transverse means 'across' and sinus was an old word for a hollow or 'channel', so the name shows a channel running across the back of the head. So, the term refers to the channel that helps 'drain' blood from the back of the brain.
