A rooster, also known as a cockerel or cock, is a male gallinaceous bird, usually a male chicken (Gallus gallus).he term rooster originates in the United States, and the term is widely used throughout North America, as well as Australia and New Zealand. The older terms cock or cockerel, the latter denoting a young cock, are used in the United Kingdom and Ireland.
The bleeding causes swelling of the brain and increased pressure in the skull. The swelling and pressure damage brain cells and tissues. Examples of conditions that can cause a hemorrhagic stroke include high blood pressure, aneurysms, and arteriovenous (ar-TEER-e-o-VE-nus) malformations (AVMs). Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps blood.
The artery can then begin to dilate or balloon out from the pressure of the blood that pulsates through the artery. Elevated blood pressures, hereditary tendencies toward weakened arteries, and traumatic injuries are also causes of aneurysms.
