  2. Carotid sinus - Wikipedia

    en.wikipedia.org/wiki/Carotid_sinus

    The carotid sinus baroreceptor can be oversensitive to manual stimulation from the pressure applied at the carotid sinus at the carotid bifurcation. It is a condition known as 'carotid sinus hypersensitivity' (CSH), 'carotid sinus syndrome' or 'carotid sinus syncope', in which manual stimulation causes large changes in heart rate and blood ...

  3. Carotid sinus nerve - Wikipedia

    en.wikipedia.org/wiki/Carotid_sinus_nerve

    The carotid branch of the glossopharyngeal nerve (carotid sinus nerve or Hering's nerve) is a small branch of the glossopharyngeal nerve (cranial nerve IX) that innervates the carotid sinus, and carotid body.

  4. Carotid body - Wikipedia

    en.wikipedia.org/wiki/Carotid_body

    The carotid body is a small cluster of peripheral chemoreceptor cells and supporting sustentacular cells situated at the bifurcation of each common carotid artery in its tunica externa. [ 1 ] [ 2 ] The carotid body detects changes in the composition of arterial blood flowing through it, mainly the partial pressure of arterial oxygen , but also ...

  5. Baroreceptor - Wikipedia

    en.wikipedia.org/wiki/Baroreceptor

    Carotid sinus baroreceptors are responsive to both increases or decreases in arterial pressure, while aortic arch baroreceptors are only responsive to increases in arterial pressure. [6] Arterial baroreceptors inform reflexes about arterial blood pressure but other stretch receptors in the large veins and right atrium convey information about ...

  6. Internal carotid artery - Wikipedia

    en.wikipedia.org/wiki/Internal_carotid_artery

    This part of the artery is known as the carotid sinus or the carotid bulb. The ascending portion of the cervical segment occurs distal to the bulb when the vessel walls are again parallel. The internal carotid runs vertically upward in the carotid sheath and enters the skull through the carotid canal.

  7. Vasomotor center - Wikipedia

    en.wikipedia.org/wiki/Vasomotor_center

    carotid body chemoreceptors, which send impulses via the glossopharyngeal nerves; aortic arch and brachiocephalic artery high-pressure baroreceptors, which send impulses via the aortic nerve [5] carotid sinus high-pressure baroreceptors, which send impulses via the glossopharyngeal nerves

  9. Peripheral chemoreceptor - Wikipedia

    en.wikipedia.org/wiki/Peripheral_chemoreceptor

    Carotid bodies are considered the primary peripheral chemoreceptor and have been shown to contribute more to a hypoxic response. However, in the chronic absence of the carotid body, the aortic body is able to perform a similar respiratory regulatory role, suggesting that it possesses efficacious mechanisms of signal transduction as well.
