Where are the left and right carotid arteries in the human body

From an anatomical point of view, there are very important left and right carotid arteries in the neck, so overall the neck is a very important part of the human body. Moreover, the left and right carotid arteries in the neck mainly supply blood to the brain through the heart, so when these two arteries are damaged, death due to excessive blood loss is likely to occur. So where are the left and right carotid arteries on the human neck located?

The right common carotid artery arises from the brachiocephalic trunk, and the left common carotid artery arises directly from the aortic arch. The common carotid arteries on both sides rise along the outside of the esophagus, trachea and larynx, and divide into the internal carotid artery and the external carotid artery at the upper edge of the thyroid cartilage. There is the internal jugular vein on the outside of the common carotid artery, and the vagus nerve behind the two. All three are wrapped in a fascial sheath.

Where is the pulsation of the carotid artery in the human body?

If you want to determine the location of the carotid artery pulsation, the best way is to do it by touch. First, slide the middle finger and index finger towards the carotid artery on one side from the throat. During the sliding process, if you feel an obvious pulsation, then this is the location where the carotid artery pulsates. In addition, there is also time to check whether it is the carotid artery.

The general inspection time is five seconds. If no pulse is felt within five seconds, it means that the patient has no pulse. When a person is checking the pulse, they should be careful not to use the thumb to check. The reason why a person is not allowed to use the thumb for examination is because the artery in the thumb is shallow, so sometimes it will delay the rescue time, so it is best not to use the thumb for examination.
