| nerve to carotid sinus | <anatomy, nerve> A branch of the glossopharyngeal nerve that innervates the baroreceptors in the wall of the carotid sinus and the chemoreceptors in the carotid body. Synonym: ramus sinus carotici, carotid sinus branch, Hering's sinus nerve, intercarotid nerve, nerve to carotid sinus, sinus nerve of Hering. (05 Mar 2000) |

| internal carotid nerve | <anatomy, nerve> The cephalic arterial ramus conveying postsynaptic sympathetic fibres from the superior cervical ganglion to the internal carotid artery to form the internal carotid plexus. Synonym: nervus caroticus internus. (05 Mar 2000) |
| internal carotid (nervous) plexus | An autonomic plexus surrounding the internal carotid artery in the carotid canal and cavernous sinus, and sending branches to the tympanic plexus, sphenopalatine ganglion, abducens and oculomotor nerves, the cerebral vessels, and the ciliary ganglion. Synonym: internal carotid venous plexus. (05 Mar 2000) |
| internal carotid venous plexus | A venous network around the internal carotid artery in the carotid canal of the temporal bone, connecting with the cavernous sinus and internal jugular vein.

| endarterectomy, carotid | The excision of the thickened, atheromatous tunica intima of a carotid artery. (12 Dec 1998) |
| external carotid nerves | A number of sympathetic nerve fibres conveyed via the cephalic arterial ramus of the sympathetic trunk which extends from the superior cervical ganglion to the external carotid artery, forming the external carotid plexus. Synonym: nervi carotici externi. (05 Mar 2000) |
| external carotid plexus | An autonomic plexus formed by the external carotid nerves surrounding the artery of the same name, and giving origin to a number of secondary plexus's along the branches of this artery and to branches to the carotid body. Synonym: plexus caroticus externus. (05 Mar 2000) |
| Abbott's artery | <anatomy, artery> An anomalous artery arising from the posteromedial proximal descending aorta, important during coarctation repair. (05 Mar 2000) |
