Confluence of sinuses
Confluence of Sinuses
The Confluence of Sinuses (pronunciation: /kɒnˈfluːəns ɒv ˈsaɪnəsɪz/), also known as Torcular Herophili, is a significant structure in the human anatomy related to the venous system of the brain.
Etymology
The term "Confluence of Sinuses" is derived from the Latin words 'confluentia' meaning 'flowing together' and 'sinus' meaning 'bay'. The term 'Torcular Herophili' is named after the ancient Greek physician Herophilus, who first described it.
Description
The Confluence of Sinuses is located at the internal base of the skull, where the superior sagittal sinus, straight sinus, and transverse sinuses meet. This confluence allows for the drainage of blood from the brain back to the heart.
