  2. Internal carotid artery - Wikipedia

    en.wikipedia.org/wiki/Internal_carotid_artery

    The internal carotid artery is an artery in the neck which supplies the anterior and middle cerebral circulation. [ 1 ] In human anatomy, the internal and external carotid arise from the common carotid artery , where it bifurcates at cervical vertebrae C3 or C4.

  3. Circle of Willis - Wikipedia

    en.wikipedia.org/wiki/Circle_of_Willis

    The posterior communicating artery is given off as a branch of the internal carotid artery just before it divides into its terminal branches - the anterior and middle cerebral arteries. The anterior cerebral artery forms the anterolateral portion of the circle of Willis, while the middle cerebral artery does not contribute to the circle.

  4. Cerebral arteries - Wikipedia

    en.wikipedia.org/wiki/Cerebral_arteries

    Posterior cerebral artery (PCA), which supplies blood to the posterior portion of the brain, including the occipital lobe, thalamus, and midbrain [5] Both the ACA and MCA originate from the cerebral portion of internal carotid artery , while PCA branches from the intersection of the posterior communicating artery and the anterior portion of the ...

  5. Carotid sinus - Wikipedia

    en.wikipedia.org/wiki/Carotid_sinus

    In human anatomy, the carotid sinus is a dilated area at the base of the internal carotid artery just superior to the bifurcation of the internal carotid and external carotid at the level of the superior border of thyroid cartilage. The carotid sinus extends from the bifurcation to the "true" internal carotid artery. [1]

  6. Carotid artery stenosis - Wikipedia

    en.wikipedia.org/wiki/Carotid_artery_stenosis

    At the throat it forks into the internal carotid artery and the external carotid artery. 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 ...

  7. Pulse - Wikipedia

    en.wikipedia.org/wiki/Pulse

    In medicine, the pulse is the rhythmic throbbing of each artery in response to the cardiac cycle (heartbeat). [1] The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery or ulnar artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint ...

  8. Baroreflex activation therapy - Wikipedia

    en.wikipedia.org/wiki/Baroreflex_activation_therapy

    The device is implanted into upper chest with the electrodes placed in the neck. [7] First, an incision is made in the neck to visualize the carotid bifurcation. The electrode is placed over the carotid artery and positioned where stimulating through it elicits a blood pressure reduction. The electrode is then sutured in place.

  9. Common carotid artery - Wikipedia

    en.wikipedia.org/wiki/Common_carotid_artery

    In at least one reported case, the artery was only 4 cm in length and divided at the root of the neck. Very rarely, the common carotid artery ascends in the neck without any subdivision, either the external or the internal carotid being absent; and in a few cases the common carotid has itself been found to be absent, the external and internal ...
