Carotid arteries: Wikis The common carotid artery is contained in a sheath known as the carotid sheath, which is derived from the deep cervical fascia and encloses also the internal jugular vein and vagus nerve, the vein lying lateral to the artery, and the nerve between the artery and vein, on a plane posterior to both.

- The carotid arteries are two large blood vessels that supply oxygenated blood to the large, front part of the brain. This is where thinking, speech, personality, and sensory and motor functions reside. You can feel your pulse in the carotid arteries on each side of your neck, right below the angle of the jaw line.arotid artery disease is also called carotid artery stenosis. The term refers to the narrowing of the carotid arteries. This narrowing is usually caused by the buildup of fatty substances and cholesterol deposits, called plaque. Carotid artery occlusion refers to complete blockage of the artery.

How Many Cranial Nerves Are There? Trigeminal Nerve (V). This is the largest cranial nerve and it performs many sensory and motor functions. It divides into three branches called the ophthalmic nerve, maxillary nerve and mandibular nerve. The trigeminal nerve innervates structures originating from the branchial arches.

What Is Carotid Stenosis? What Is Carotid Stenosis? Carotid stenosis, or carotid artery disease, is a narrowing or blockage of the carotid arteries. Located in the side of your neck, your left and right carotids are two large arteries that carry oxygen-rich blood to your brain. You can feel your carotids pulsate when you place your index finger right below the angle of your jaw. Carotid stenosis is dangerous because it can decrease blood flow to your brain.

Picture of the Carotid Artery The carotid sinus, or carotid bulb, is a widening of a carotid artery at its main branch point. The carotid sinus contains sensors that help regulate blood pressure. The carotid artery pulse can normally be felt in the neck by pressing the fingertips against the side of the windpipe, or trachea. Stroke: A sudden blood clot in the carotid artery can interrupt blood flow to the brain, causing a stroke. 2  Fragments of cholesterol plaque in the carotid artery may also travel into the brain to cause a stroke.

Internal carotid artery Internal carotid artery. The common carotid artery is found bilaterally, with one on each side of the anterior neck. Each common carotid artery is divided into an external and internal carotid artery. These arteries transfer blood to the structures inside and outside of the skull.he external carotid artery brings blood to structures outside the skull, primarily the face, and the internal carotid to structures inside the skull, including the brain.
