Internal carotid artery
Internal Carotid Artery
The Internal Carotid Artery (pronounced: in-ter-nal kuh-rot-id ar-ter-ee) is a major blood vessel in the head and neck region of the human body.
Etymology
The term "carotid" is derived from the Greek word "karōtides" meaning "to stupefy" or "to plunge into deep sleep", as compression of these arteries was believed to cause unconsciousness.
Anatomy
The Internal Carotid Artery originates from the Common Carotid Artery and ascends in the neck to supply the brain and eyes with oxygenated blood. It is divided into two main sections: the cervical part (in the neck) and the cerebral part (in the brain).
Branches
The branches of the Internal Carotid Artery include the Ophthalmic Artery, Anterior Cerebral Artery, Middle Cerebral Artery, and Posterior Communicating Artery.
Clinical Significance
The Internal Carotid Artery is of significant clinical importance as it is often involved in conditions such as Stroke, Transient Ischemic Attack, and Carotid Artery Disease.
