ABSTRACT
Carotid body chemoreceptors are complex secondary receptors. There are chemical and electric connections between glomus cells (GC/GC) and between glomus cells and carotid nerve endings (GC/NE). Chemical secretion of glomus cells is accompanied by GC/GC uncoupling. Chemical GC/NE transmission is facilitated by concomitant electric coupling. Chronic hypoxia reduces GC/GC coupling but increases G/NE coupling. Therefore, carotid body chemoreceptors use chemical and electric transmission mechanisms to trigger and change the sensory discharge in the carotid nerve.
