Pituitary apoplexy is attached to the hypothalamus, a part of the brain, by a stalk that also contains the blood vessels that supply the gland. It is unclear why pituitary tumors are five times more likely to bleed than other tumors in the brain. There are various proposed mechanisms by which a tumor can increase the risk of either infarction (insufficient blood supply leading to tissue dysfunction) or hemorrhage. The pituitary gland normally derives its blood supply from vessels that pass through the hypothalamus, but tumors develop a blood supply from the nearby inferior hypophyseal artery that generates a higher blood pressure,
Tank controls 3D games. Most first-person shooter games still use a version of tank controls with the WASD keys, but the use of a mouse or analog stick makes turning easy. Tank controls Tank controls refers to a control system used in video games. In a game with tank controls, players control movement relative to the position of the player character. Pressing up (for example on a D-pad, analog stick, or cursor movement keys) on the game controller moves the character in the direction they face, down reverses them, and left and right rotates them. This differs from many 3D games, in
