Kaplan anatomy coloring book - part 6

Não được nuôi dưỡng bởi hai ống động mạch chính. Việc đầu tiên trong số này là các dòng chảy từ động mạch cảnh bên trong. Máu từ động mạch cảnh bên trong xuất phát từ cổ và đi vào một đường tròn được gọi là động mạch vòng tròn (vòng tròn của Willis) | chapter Eight I KAPLAN . 011 Cardiovascular System I medical 211 BRAIN ARTERIES The brain is nourished by two main arterial conduits. The first of these is the flow from the internal carotid arteries. Blood from the internal carotid arteries comes from the neck and enters a circular pathway known as the arterial circle circle of Willis . The other conduit comes from the vertebra and these are the vertebral arteries. These arteries connect at a vessel called the basilar artery and it leads to the arterial circle. The arterial circle consists of the anterior communicating arteries and the posterior communicating arteries. From this circle blood then moves into one of many arteries that feed the brain. The cerebrum is fed by the anterior middle and posterior cerebral arteries. The cerebellum is fed by the cerebellar arteries. If there is a blockage in any of these vessels then blood does not reach the affected part of the brain and this produces a stroke. Color the arteries red and label the illustration. Arteries are abbreviated aa. Answer Key a. Anterior cerebral a. b. Middle cerebral a. c. Internal carotid a. d. Posterior cerebral a. e. Basilar a. f. Anterior communicating a. g. Arterial circle h.

Blood in the axillary artery travels to the anterior scapula by the subscapular artery to the external chest wall by the lateral thoracic artery to the upper humeral region by the posterior circumflex humeral artery and to the distal regions of the arm by the brachial artery. The brachial artery is the major artery of the arm and it divides distally to form the radial and ulnar arteries. The radial artery is frequently palpated at the wrist to determine the pulse rate. The radial and ulnar arteries rejoin called .
