They protrude into the venous sinuses of the brain, and allow cerebrospinal fluid (CSF) to exit the sub-arachnoid space and enter the blood stream.Coronal suture: The coronal suture is a dense, fibrous connective tissue joint that separates the frontal and parietal bones of the skull. At birth, the bones of the skull do not meet.SumatriptanBifrontal craniotomy: a bifrontal craniotomy is a surgical process which is used to target different tumors or malfunctioning areas of the brain.http://www.LaminectomyTrigeminovascular system: The trigeminovascular system consists of neurons in the trigeminal nerve that innervate cerebral blood vessels. It has been hypothesized that the trigeminovascular system may be involved in some types of headaches.Epidural space: In the spine, the epidural space (from Ancient Greek ἐπί, "on, upon" + dura mater also known as "epidural cavity", "extradural space" or "peridural space") is an anatomic space that is the outermost part of the spinal canal. It is the space within the canal (formed by the surrounding vertebrae) lying outside the dura mater (which encloses the arachnoid mater, subarachnoid space, the cerebrospinal fluid, and the spinal cord).RhinorrheaTrigonocephalyJakob Buchli: Jakob Buchli (4 March 1876 – 1 April 1945) was a Swiss design engineer in the field of locomotive construction.Cranial vault: The cranial vault is the space in the skull within the neurocranium, occupied by the brain. In humans, the size and shape of the brain, may be affected by the size of the vault as shown in craniometry, but studies relating it to intelligence have found no conclusive evidence.MeningiomaSubdural hematomaC14 Timberwolf: The C14 Timberwolf MRSWS (Medium Range Sniper Weapon System) is a bolt action sniper rifle built by the Canadian arms company PGW Defence Technologies Inc. In 2005 they won the contract to supply the Canadian Forces Land Command with the C14 Timberwolf MRSWS for $4.Pneumatocele: A pneumatocele is a cavity in the lung parenchyma filled with air that may result from pulmonary trauma during mechanical ventilation.Scalp reconstruction: Scalp reconstruction is a surgical procedure for people with scalp defects. Scalp defects may be partial or full thickness and can be congenital or acquired.MitiglinideMeningitis Vaccine ProjectAtmosphere-Space Transition Region Explorer: Atmosphere-Space Transition Region Explorer (ASTRE) is an explorer program mission to study the interaction between the Earth's atmosphere and the ionized gases of space in an effort to understand space-induced currents in electric power grids originate as well as improve satellite drag models. The principal investigator is Robert Pfaff Jr.PolytetrafluoroethyleneMigraine Disability Assessment Test: The MIDAS or Migraine Disability Assessment Test is a test used by doctors to determine how severely migraines affect a patient's life. Patients are asked questions about the frequency and duration of their headaches, as well as how often these headaches limited their ability to participate in activities at work, at school, or at home.
