Summary The carotid body was found in/on the cavernous sinus of the carotid rete of the Japanese miniature Shiba goat by light and electron microscopies. The carotid body‐like aggregated cell group consisted of two types of cells arranged in the lobule. The first type contained membrane‐bound granular vesicles; these cells resembled to the type‐I cells in the carotid body. The second type contained no cytoplasmic vesicles, and were located in the periphery, investing the type‐I cells. These features appear to be consistent with those of the type‐II cells in the carotid body. The nerve ending showed two peculiar features in the intercellular space of type‐I cells. The clear vesicle‐containing nerve ending showed a structural feature indicative of efferent synapsis. The small granular vesicle‐containing nerve ending has been described as a baroreceptor‐like ending by VERNA (1979). All of these features are typical characteristics of the carotid body.
