Abstract
The carotid body detects chemical changes in the blood such as PO2, PCO2 and pH, and generates afferent discharges in the carotid nerve. During stimulation, the glomus cells release endogenous substances (ACh, catecholamines, and neuropeptides) toward the carotid nerve terminals. To understand how secretion occurs, we have studied the electric connections between glomus cells at rest and during activity elicited by ‘natural’ stimuli, or the transmitters (Monti-Bloch et al., 1990, 1993). In other secretory organs, adjoining cells are electrically coupled and they uncouple (fully or partially) during secretion (for refs. see Bennett & Spray, 1985; Hertzberg & Johnson, 1988; Bennett et al., 1991).
