  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 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 ...

  4. 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.

  5. Baroreceptor - Wikipedia

    en.wikipedia.org/wiki/Baroreceptor

    Arterial baroreceptors are located in the carotid sinus (at the bifurcation of common carotid artery into external and internal carotids) and in the aortic arch. [5] The baroreceptors can identify the changes in both the average blood pressure or the rate of change in pressure with each arterial pulse.

  6. Ophthalmic artery - Wikipedia

    en.wikipedia.org/wiki/Ophthalmic_artery

    The ophthalmic artery (OA) is an artery of the head.It is the first branch of the internal carotid artery distal to the cavernous sinus.Branches of the ophthalmic artery supply all the structures in the orbit around the eye, as well as some structures in the nose, face, and meninges.

  7. Carotid sinus nerve - Wikipedia

    en.wikipedia.org/wiki/Carotid_sinus_nerve

    It conveys information from the baroreceptors of the carotid sinus to the vasomotor center in the brainstem (in order to mediate blood pressure homeostasis), and from chemoreceptors of the carotid body [further explanation needed] (mainly conveying information about partial pressures of blood oxygen, and carbon dioxide).

  8. Carotid sheath - Wikipedia

    en.wikipedia.org/wiki/Carotid_sheath

    The carotid sheath is a condensation of the deep cervical fascia [1]: 578 enveloping multiple vital neurovascular structures of the neck, [2] including the common and internal carotid arteries, the internal jugular vein, the vagus nerve (CN X), and ansa cervicalis. [1]: 578 [2] The carotid sheath helps protects the structures contained therein. [2]

  9. Cavernous sinus - Wikipedia

    en.wikipedia.org/wiki/Cavernous_sinus

    The carotid siphon of the internal carotid artery, and cranial nerves III, IV, V (branches V 1 and V 2) and VI all pass through this blood filled space. Both sides of cavernous sinus are connected to each other via intercavernous sinuses. The cavernous sinus lies in between the inner and outer layers of dura mater. [3]
