Artery Laryngeal Caudal

The caudal laryngeal artery (lat. a. laryngea caudalis) is a blood vessel in the neck that delivers blood to the lower parts of the larynx, as well as to the upper part of the thyroid gland. It is a branch of the common carotid artery and passes along the posterior edge of the clavicle through the interclavicular fossa into the posterior mediastinum. The caudal caudal artery is separated from the prevertebral artery by the parietal layers of the rectus sheath. This is an important anatomical formation, since injuries to the laryngeal vessels can lead to serious blockage or even death of the patient. That is why knowledge of the anatomy of this artery is of great importance.

The posterior laryngeal artery (laingica postérior) in its development flows in the medial triangle of Trakatas, which is limited by the posterior cricoid surface and two cricoid cheeks. However, at the level of the upper edge of the thyroid cartilage, it is located in its usual place. An important feature of its passage is that it passes behind the internal jugular vein, forming a higher and anterior location compared to the lumen of the lateral part of the neck and the cavity of the external jugular fossa. Below the entrance to the neck, the artery passes under the upper lobe of the thyroid gland and constitutes the physiological anatomical term “thyroid-cervical tract”, after which it passes into the esophageal space in the region of the upper end of the esophagus.

At the level of the cricoid process of the larynx, one of the branches departs from it - the initial thyroid artery, which supplies blood to the anterior lobe of the thyroid gland and part of the root of the tongue, and the other branch - the recurrent superior laryngeal artery departs below the hyoid bone from the aortic arch.

Like all cervical arteries, the posterior laryngeal artery is distinguished by the presence of arcuate arteries, which are formed by branches arising on its segments, due to the fact that each segment of the artery is divided into a number of branches, some of which anastomose with each other to ensure blood circulation of the corresponding segments of the laryngeal trachea and neck tissues. In turn, the vessels arising from the main branch of the laryngeal posterior artery include the recurrent arteries, bronchial and thyrohyoid arteries.
