Survey of the Cerebrovascular System

負責學生：丁筱柔

NC378L01 丁筱柔 9580033

Discuss the importance of blood circulation to the brain

探討腦內血液循環的重要

NC378

血液提供腦需要的養分，例如葡萄糖和氧氣；也同時移除二氧化碳。若腦中缺乏血液一段短暫的時間，就會造成不可逆的細胞本體損傷。時間若長達4-6分鐘則可能會導致無法復原的腦傷。

NC378L02 許婷婷 9580035

List the major arteries that transport blood to the cerebrum.

列出運送血液至大腦的主要動脈

NC382~385 Figure17-1、Figure17-2、Table17-3

NC378L03 黃郁文 9580036

Describe the cortical region supplied by each major artery.

= Describe which cortical region is supplied by which major artery!

描述皮質部位各個提供血液的主要血管。

NC382T17-03

NC378L04 彭康政 9580038

Discuss the blood supply for the brainstem, cerebellum, and spinal cord

討論腦幹、小腦，還有脊髓的血液供應

NC380T17-01的Table有腦幹、小腦及脊髓的血管，NC384的Blood Supply to Spinal Cord講到了脊髓的血液供應。

NC378L05 陳穎萱 9580039

Explain common symptoms associated with involvement of major arteries.

解釋和主要動脈有關係的一般常見症狀

NC387~389

Table 17-6( NC387 )、Table17-7( NC388 )、Figure17-7( NC388 )、Figure17-8( NC389 )

NC378L06 黃宜嬅 9580040

List common points of anastomoses in the vascular system

列出與血管系統常見的連結__

NC387

運輸方向可分為動脈（artery）、靜脈（vein）與微血管（capillary）。動脈從心臟將血液帶至身體組織，靜脈將血液自組織間帶回心臟，微血管則連接動脈與靜脈，是血液與組織間物質交換的主要場所。

NC378L07 黃宏舜 9580042

Explain the significance of potential collateral circulation

解釋潛在的側枝循環重要性

NC384~385

相關資料：楊教授說，有冠心病的中老年人由於患病時間較長，人體這台精密的機器已經慢慢地進行了“自我調整”，為主動脈血管開辟了很多小路，即側枝循環，引流血液供應心肌，所以不易出現嚴重的急性心肌梗死，往往會有一個過渡期。但年輕人平時幾乎沒有症狀，也就沒有開發側枝循環，長期的不良生活習慣容易造成冠狀動脈斑塊破裂，導致冠狀動脈急性閉塞。一旦堵塞，沒有側枝循環，梗死范圍大，發生猝死的幾率大大增加。

Describe the mechanism regulating blood flow to the brain

= What is the mechanism to regulate how blood flows into the brain

描述調控大腦血流的機制

NC391~393

reflexive contraction、expansion of arterial walls、CO2 blood level and blood pressure changes. The maintain a constant blood flow with mean arterial pressure in range of 60-1401 mm Hg. On average, for normal functioning the brain supply of 45-55 ml/100gm brain tissue per minute. If this flow amount is reduced, it affects the brain’s ability to function normally. The arteries respond to the blood volume by altering their resistance to blood flow from the heart. They respond by dilating if the volume of blood pumped through the artery is reduced. When the volume increases, arteries constrict. The Cushing response is a systematic rise in the pressure of blood in the case of increased intracranial pressure. The Monroe-Kelly principle represents the brain’s internal ability for self-adjusting intracranial volumes of blood, CSF, and tissue content. It manages its intracranial pressure reflexively by decreasing the volume in the other element, such as a decrease in blood flow in the case of vessel constriction due to lower blood CO2.
