title: [What is the role of the sympathetic nervous system in digital vasospasms?].
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.
