Name the main sinuses of the brain. What major vein do the sinuses eventually drain to? Hint: it exits the skull. For each major sinus, describe its complete course to the point where drainage leaves the skull. If applicable, include a description of which dural structure that sinus is contained in. What tissue forms the sinuses? What is the difference between a sinus and a vein? These questions may require combining info from Gross Neuroanatomy and the Blood Supply lectures.
