    en.wikipedia.org/wiki/Common_carotid_artery

    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. On opening the sheath, each of these three ...

    The internal carotid artery supplies the brain, and the external carotid artery supplies the face. This fork is a common site for atherosclerosis, an inflammatory build-up of atheromatous plaque inside the common carotid artery, or the internal carotid arteries that causes them to narrow. [3] [4]

    en.wikipedia.org/wiki/Carotid_body

    The carotid body is situated on the posterior aspect of the bifurcation of the common carotid artery. [3] The carotid body is made up of two types of cells, called glomus cells: glomus type I cells are peripheral chemoreceptors, and glomus type II cells are sustentacular supportive cells. Glomus type I cells are derived from the neural crest. [4]

  8. External carotid artery - Wikipedia

    en.wikipedia.org/wiki/External_carotid_artery

    The external carotid artery arises from the common carotid artery just inferior to the upper border of the thyroid cartilage. [1]At its origin, this artery is closer to the skin and more medial than the internal carotid, and is situated within the carotid triangle.

  9. Carotid artery dissection - Wikipedia

    en.wikipedia.org/wiki/Carotid_artery_dissection

    Carotid artery dissection is a serious condition in which a tear forms in one of the two main carotid arteries in the neck, allowing blood to enter the artery wall and separate its layers (*dissection*). This separation can lead to the formation of a blood clot, narrowing of the artery, and restricted blood flow to the brain, potentially ...
