Sympathetic innervation of the pulmonary artery, ascending aorta, and coronar glomera of the rabbit. A fluorescence microscopic study.
Adrenergic nerve fibres were demonstrated in the connective tissue of the rabbit coronar glomera by means of the formaldehyde-induced fluorescence technique for catecholamines. This type of innervation is similar to the adrenergic nerve supply to the rabbit and cat carotid body. Adrenergic fibres terminate subendothelially and only a few can be traced to type I cells in the glomera coronaria. The sympathetic innervation of the ascending aorta is exceedingly sparse in contrast to the pulmonary trunk, while vasa vasorum of the ascending aorta exhibit a dense sympathetic innervation.
