Abstract

After cutting the sinus nerve of the rabbit and implanting the proximal stump into the adventitial layer of the external carotid artery a neuroma develops which 3–4 months postoperatively is intermingled with sinusoids and loose connective tissue. It is thus structurally similar to the carotid body except for the absence of Type I and Type II cells. We refer to the neuroma, sinusoids and connective tissue as a ‘regeneration product’. Electrophysiological recordings show a chemoreceptive function of the regeneration product of the sinus nerve which is quite similar to that of normal chemoreceptors. This means that some parts of the neural tissue in the ‘regeneration product’ must themselves be chemoreceptors and that parenchymal tissue is not needed for chemoreception. We suggest that Type I and Type II cells of the carotid body may take part in the environmental adjusting of chemoreceptors or that they may be secretory, paraganglionic cells.
