Common Carotid Arteries
ANATOMY
Common Carotid Artery is a pair of two arteries meaning one for each half of the body. The passage for their blood supply is the same without the difference of their origin. From the Brachiocephalic Trunk, the Right Common Carotid Artery originates in the Neck. The Left Common Carotid Artery originates in the Thoracic region from the Aortic Arch. These two Common Carotid Arteries divide at the upper region of the Thyroid Cartilage. Common Carotid Artery is contained in a sheath called Carotid Sheath, derived from Deep Cervical Fascia. Their average diameter in adult is from 6.5 mm to 6.1 mm.
FUNCTION
Common Carotid Artery has two branches: internal carotid artery and external carotid artery. The Internal Carotid Artery being the larger of the two has an important role of supplying nutrient filled blood to the brain. Without the glucose transport by this artery brain would be unable to carry out its functions. External Carotid Artery, although smaller than the Internal Carotid Artery, supplies many structures. It divides into smaller vessels like Superior Thyroid and Lingual supply blood to tongue and Facial arteries.
CLINICAL SIGNIFICANCE
Common Carotid Artery is use to measure the pulse of a person in shock lacking pulse in any Peripheral Arteries of the body.Soreness of the Common Carotid Arteries causes a condition called Carotidynia.
