Hypoxia and Hypercapnia Deplete Clear Vesicles but Not Dense-Cored Vesicles in the Carotid Body’s Sensory Nerves

摘要: The nerves that terminate on the carotid body’s glomus cells have been a morphological curiosity since de Castro deduced they sensory function (1), but it was not until nerve endings were examined with electron microscope some of their most interesting features recognized. One such feature is presence numerous 60-nm cytoplasmic vesicles, which resemble synaptic vesicles efferent (motor) (2–4). Some these cluster near morphologically typical junctions at are presynaptic to cells. Larger electron-dense cores also present in endings.
