Major Arteries of the Head and Neck

Your circulatory system contains a vast network of blood vessels, which includes arteries, veins , and capillaries. According to the Cleveland Clinic, if you laid out all of the blood vessels of the body they would be about 60, miles long! Arteries are a type of blood vessel. They work to carry blood away from the heart. In contrast, veins carry blood back to the heart. Because arteries are moving blood being pumped out by the heart, the walls of arteries are thicker and more elastic than those of veins.

This is because the blood in the arteries is passing through with a higher pressure than in veins. The thick, elastic walls of arteries accommodate that pressure. Arteries can also be divided into elastic and muscular arteries based off of the material of their tunica media or middle layer. Arteries come in a variety of sizes. The largest artery of the body is the aorta, which begins at the heart.

As they move further from the heart, arteries branch off and become increasingly smaller. The smallest arteries are called arterioles. Arterioles connect to capillaries, which are the smallest blood vessels and are where the exchange of oxygen, nutrients, and waste occurs between the blood and the cells of the body. After this exchange occurs, the blood enters the venous system , where it travels back toward the heart.

Below are some of the major arteries that are found in the body and the organs and tissues that they service. The largest and most important artery in the circulatory system is the aorta. The aorta is connected to your heart via the aortic valve. The arteries are blood vessels in the circulatory system that move blood away from the heart.

This occurs through two different circuits. The systemic circuit supplies the organs and tissues of the body with oxygen and other nutrients. The pulmonary circuit allows blood to acquire fresh oxygen while getting rid of carbon dioxide. Damaged or narrowed arteries can lead to the body not getting an adequate blood supply, which can put you at risk for things such as heart attack or stroke. But what does that mean? Checking your blood pressure at home with a manual or automated device can help you monitor your health between doctor visits.

Please consult the latest official manual style if you have any questions regarding the format accuracy. The temporal bone forms part of the side and base of the skull. It constitutes two-thirds of the floor of the middle cranial fossa and one-third of the floor of the posterior fossa. There are four parts to the temporal bone:. Anterior, superior, posterior, auricular The temporalis muscle attaches to the squamosa portion of the temporal bone and not to the mastoid process. The auricle Figure is made of elastic cartilage, the cartilaginous canal of fibro-cartilage.

Head and neck anatomy is important when considering pathology affecting the same area. In radiology, the 'head and neck' refers to all the anatomical structures in this region excluding the central nervous system, that is, the brain and spinal cord and their associated vascular structures and encasing membranes i. Many pathologies are confined to a particular area of the head and neck making separation of this section of the human body exceptionally useful. The deep anatomy is separated by fascial planes into seven deep compartments of the head and neck :. Many of the disease states that affect the deep structures of the head and neck are confined to one compartment. However, there are some diseases that are considered trans-spatial diseases. There are several triangles of the neck that are more surgically focused, first described from early dissection-based anatomical studies which predated cross-sectional anatomical description based on imaging:.

The common carotid arteries are present on the left and right sides of the body. These arteries originate from different arteries but follow symmetrical courses. The right common carotid originates in the neck from the brachiocephalic trunk ; the left from the aortic arch in the thorax.

Если Танкадо убьют, этот человек опубликует пароль. - Его партнер опубликует ключ? - недоуменно переспросила Сьюзан. Стратмор кивнул: - Он разместит его в Интернете, напечатает в газетах, на рекламных щитах. Короче, он отдаст ключ публике. Глаза Сьюзан расширились.

Информация, которую он выдал… Она резко подняла голову. Возможно ли. Информация, которую он выдал. Если Стратмор получил от Следопыта информацию, значит, тот работал. Она оказалась бессмысленной, потому что он ввел задание в неверной последовательности, но ведь Следопыт работал.

 Не кажется ли тебе, что это звучит как запоздалое эхо.

 Вот. Она нахмурилась. - Ты не заметил ничего. Ну, может, дошел какой-нибудь слушок.
