Abstract
The synaptic junctions between glomus cells and nerve endings in the rabbit carotid body were studied by EM. Many were morphologically afferent and glomus cells were presynaptic to nerve endings; occurrence of efferent synapses was less common than that of afferent synapses. Reciprocal synapses in which 2 or more junctions of opposite polarity were lying side by side were frequently seen particularly between large nerve endings and glomus cells. Some single synapses were part of reciprocal synapses seen through examination of serial sections. The possible participation of dopamine in a modulatory feedback loop through reciprocal synapses in the rabbit carotid body is supported.This publication has 3 references indexed in Scilit:
