  • Title: Denervation increases myogenic tone in a resistance artery in the growing rabbit ear.
    Author: Mangiarua EI, Joyce EH, Bevan RD.
    Journal: Am J Physiol; 1986 May; 250(5 Pt 2):H889-91. PubMed ID: 3706561.
    Abstract:
    The effect of chronic sympathetic and sensory denervation of the growing rabbit ear vasculature on myogenic tone in a resistance artery was studied. Unilateral superior cervical ganglionectomy and section of greater and anterior auricular nerves were performed at 4 wk of age. Compared with the contralateral control, 2 and 6 wk later, the denervated artery developed greater stretch-dependent myogenic tone. This phenomenon may partially account for the return of tone described in the denervated ear vasculature.
