Axillary pulse: located inferiorly of the lateral wall of the axilla; Brachial pulse: located on the inside of the upper arm near the elbow, frequently used in place of carotid pulse in infants (brachial artery) Radial pulse: located on the lateral of the wrist (radial artery). It can also be found in the anatomical snuff box. Commonly, the ...
The pulse is taken by palpating the artery just deep to the anterior border of the sternocleidomastoid muscle at the level of the superior border of the thyroid cartilage. Presence of a carotid pulse has been estimated to indicate a systolic blood pressure of more than 40 mmHg, as given by the 50% percentile. [8]
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 ...

The pulses should be palpated, first the radial pulse commenting on rate and rhythm then the brachial pulse commenting on character and finally the carotid pulse again for character. The pulses may be: Bounding as in large pulse pressure found in aortic regurgitation or CO 2 retention.
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 ...
The parietal branch of the superficial temporal artery (posterior temporal) is a small artery in the head.It is larger than the frontal branch and curves upward and backward on the side of the head, lying superficial to the temporal fascia; it joins with its fellow of the opposite side, and with the posterior auricular and occipital arteries.
All interventions for carotid revascularization (carotid endarterectomy, carotid stenting, and transcarotid artery revascularization) carry some risk of stroke; however, where the risk of stroke over time from medical management alone is high, intervention may be beneficial. Carotid artery stenting and carotid endarterectomy have been found to ...
