The word "arteria carotis communis" is a term used in anatomy to refer to the common carotid artery. The spelling of this word follows the rules of Latin spelling since it originates from the Latin language. According to the International Phonetic Alphabet (IPA), it is pronounced as /ɑːˈtɪəriə kəˈroʊtɪs ˈkɒmjʊnɪs/. It is important to accurately spell and pronounce this term in medical settings to ensure clear communication and avoid misunderstandings.
The "arteria carotis communis", commonly known as the common carotid artery, is a crucial blood vessel located in the neck that supplies oxygenated blood to the head and neck region. It is one of the paired arteries, with one on each side of the neck, and is a major conduit for blood flow to the brain.
The common carotid artery originates from the brachiocephalic trunk on the right side and the aortic arch on the left side of the body. It then ascends vertically in the neck, alongside the trachea, towards the base of the skull. At approximately the level of the upper border of the thyroid cartilage, it typically bifurcates into two main branches, namely the external and internal carotid arteries.
The external carotid artery primarily supplies blood to the face, scalp, and neck, while the internal carotid artery is responsible for supplying blood to the brain. These two branches together play a vital role in maintaining adequate blood circulation, delivering essential nutrients and oxygen to their respective regions.
The common carotid artery is extensively used in medical interventions and procedures, such as carotid artery surgery or the placement of a carotid stent, to prevent or treat conditions like atherosclerosis or stroke. Its pulsations can also be palpated during a physical examination to assess circulation and blood flow to the brain.
Common carotid; origin, right from innominate, left from arch of aorta; runs upward in the neck and divides opposite upper border of thyroid cartilage into terminal branches, external and internal carotid.
