Abstract
The sympathetic activity is modulated by the cerebral cortex, hypothalamus, medullary vasomotor centers, and spinal cord. Finger blood flow is mainly under the control of the sympathetic nervous system. In digital vasospasm, an increased activity of the sympathetic nervous system is opposed to a local abnormality in the digital arteries. This controversy is discussed with respect to general and local control mechanisms in the peripheral blood circulation.
摘要
交感神经活动受大脑皮层、下丘脑、延髓血管运动中枢和脊髓调节。手指血流量主要受交感神经系统控制。在手指血管痉挛中，交感神经系统活动增强与手指动脉局部异常相互作用。本文就外周血液循环中的一般和局部控制机制对这一争议进行了讨论。
