The purpose of this study was to determine the morphology of

the rabbit carotid body and its artery at the light microscopy

level. The carotid body was situated between the internal and

external carotid arteries after the bifurcation point of the

common carotid artery. The carotid body was usually found to

be a single, ovoid tissue mass but, in some cases it consisted of

two or three parts. More carotid bodies were supplied by a

single carotid body artery (glomic artery) which arose from the

common carotid artery or the internal or external carotid

arteries near the bifurcation point of the common carotid

artery. In only one case were there two arteries which arose

from opposite sides of the external carotid artery at its origin.

There was a distinguishable sinus (glomic sinus) at the origin of

the glomic artery. This artery had a thin wall with elastic laminae

in the sinus area which become thinner distal to the sinus.
