(BQ) Part 2 book “Atlas on X-ray and angiographic anatomy” has contents: Angiograms, productin of x-rays, digital subtractin angiography, computed and digital radiography, picture archiving and communicatins system, computed tomography contrast media. | 7 CHAPTER Angiograms CEREBRAL CIRCULATION Normal Intracranial Arterial System Branches of the aortic arch: Brachiocephalic artery, the left common carotid artery, and left subclavian artery (Flow chart ). The extracranial carotid arteries: The right common carotid artery usually arises from the bifurcation of the brachiocephalic artery. The left common carotid artery arises from the aortic arch distal to the origin of brachiocephalic artery. Both the right and left common carotid arteries bifurcate into the external and internal carotid arteries on either side at C4- C5 level. Branches of the external carotid artery: Superior thyroidal artery, ascending pharyngeal artery, lingual artery, occipital artery, facial artery, posterior auricular artery, internal maxillary artery and superficial temporal artery. The internal maxillary artery branches are superficial temporal artery, middle meningeal artery, accessory meningeal artery and anterior deep temporal artery. The superior thyroid artery supplies the thyroid and larynx. The ascending pharyngeal artery supplies the nasopharynx and tympanic cavity. The lingual artery supplies the tongue, floor of the mouth and submandibular gland. The occipital artery supplies the scalp and upper cervical musculature. Facial artery branches supply the palate, pharynx, orbit, face and important anastomosis with other external carotid artery branches. The superficial temporal artery and posterior auricular arteries supply the scalp, buccal region and ear structures. The internal maxillary artery gives vascular supply to temporalis muscles, meninges, paranasal sinuses and mandible. While traversing the foramen spinosum, the middle meningeal artery may supply a branch, through the petrous bone, to the facial nerve. Internal carotid artery: The intracranial portions are petrous and cavernous portions. Petrous portion of internal carotid artery: The ICA while passing through the carotid canal, gives of the Vidian artery which .
