External Carotid Artery

The External Carotid Artery (pronounced: ex-ter-nal ka-rot-id ar-ter-y) is a major artery in the human body that supplies blood to the face and neck.

Etymology

The term "External Carotid Artery" is derived from the Greek words 'karos', meaning 'stupor', and 'eidos', meaning 'form or shape'. This is in reference to the artery's function of supplying blood to the head, which, if obstructed, can lead to unconsciousness.

Anatomy

The External Carotid Artery is one of the two main divisions of the Common Carotid Artery, the other being the Internal Carotid Artery. It begins at the level of the fourth cervical vertebra and ascends in the neck to supply the exterior of the head, the face, and the greater part of the neck.

Branches

The External Carotid Artery has eight branches:

  1. Superior Thyroid Artery
  2. Ascending Pharyngeal Artery
  3. Lingual Artery
  4. Facial Artery
  5. Occipital Artery
  6. Posterior Auricular Artery
  7. Superficial Temporal Artery
  8. Maxillary Artery

Each of these branches has its own specific area of distribution.

Clinical Significance

The External Carotid Artery is of clinical significance as it is often involved in conditions such as Carotid Artery Stenosis and Carotid Artery Dissection. It is also a key landmark in surgical procedures involving the neck.
