Summary The bilateral distribution of carotid body type-I cells was investigated in five rabbits, rats, guinea-pigs and mice by serially sectioning the carotid bifurcation regions. Carotid body type-I cells occurred bilaterally in close proximity to the wall of the internal carotid artery in the rabbit, rat and mouse and to the wall of the ascending pharyngeal artery in the guinea-pig. The rat carotid body was sometimes recessed into the lateral aspect of the superior cervical ganglion and was the most easily defined organ in the four animals studied. Caudally, and separate from the principal mass of carotid body type I cells, isolated groups of periadventitial type-I cells were observed in the connective tissues around the internal carotid artery and adjacent to the carotid bifurcation and common carotid artery in the rabbits only. An overall picture of the carotid body in the four animals was constructed. In all specimens rostral-caudal dimensions were recorded and compared bilaterally.
