Where does the third ventricle go through?
Cerebral aqueduct into the 4th ventricle
Where does the 4th Ventricle go through?
Through the lateral and medial apertures
The loss of cerebral control following injury; An immediate and temporary disturbance of brain functions
Concussion
A crushing compression of the brain that leads to hemorrhaging and swelling
Contusion
A cutting wound that penetrates the skull; Results in bleeding
Laceration
A hemorrhage that is due to a fracture or trauma to the head; Blood starts to pool. If unrelieved could die in days or weeks

Stiff neck
Temporary lack of circulation to a part of the brain; Could cause ischemia?
Transient Ischemic Attack
What is the main side effect of Transient Ischemic Attacks?
Mini Strokes
An apoplexy/ Stroke; The Sudden death of some brain cells due to lack of oxygen caused by a blockage or rupture of an artery in the brain

What does the Cerebrovascular Accident all depend on?
