carotid bifurcation

carotid bifurcation

[TA]
the division of the common carotid artery into internal and external carotid arteries; it occurs at the level of the superior border of the thyroid cartilages (vertebral level C4), The carotid body and sinus occur in relation to the carotid bifurcation.
