Occipital sinus
organ In the brain
The occipital sinus is the smallest of the dural venous sinuses. It is usually unpaired, and is sometimes altogether absent. It is situated in the attached margin of the falx cerebelli. It commences near the foramen magnum, and ends by draining into the confluence of sinuses.
Occipital sinuses were discovered by Guichard Joseph Duverney.
Anatomy
The occipital sinus is present in around 65% of individuals. It is usually single, but occasionally paired.
It is situated in the attached margin of the falx cerebelli.
Course
The occipital sinus commences around the margin of the foramen magnum by several small venous channels (one of which joins the terminal part of the sigmoid sinus). It terminates by draining into the confluence of the sinuses.
Begin with the source’s own compact description: “Occipital sinus” is organ In the brain. The dossier treats that line as a proposition to test through Occipital, sinus and organ, not as a finished interpretation.
Why this record matters
The phrase “organ In the brain” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 18, 2025. The linked authority identifier is Q10369487. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
