The superior thyroid artery is the first branch of the external carotid artery. It arises from the external carotid artery at the level of the hyoid bone.

2022年8月26日 · The external carotid artery (ECA) is one of the two terminal branches of the common carotid artery that has many branches that supplies the structures of the neck, face and head. The other terminal branch is the internal carotid (ICA), which is somewhat larger than the ECA, which supplies the intracranial structures.

The external carotid artery is the major artery of the head and upper neck. It arises from the common carotid artery . It terminates by splitting into the superficial temporal and maxillary artery within the parotid gland .

At the location of the upper border of the thyroid cartilage (typically at the level of the fourth or fifth cervical vertebra), the common carotid arteries bifurcate into the ECA and ICA. This bifurcation point is clinically significant as it serves as a point for the location of the "carotid body," a chemoreceptor, and the "carotid sinus," a ...

When you see this term mentioned in a radiology report, it’s referring to one of the two main branches that split from the common carotid artery.

2023年7月24日 · At the location of the upper border of the thyroid cartilage (typically at the level of the fourth or fifth cervical vertebra), the common carotid arteries bifurcate into the ECA and ICA.

The external carotid artery (ECA), a branch of the common carotid artery (CCA), commences at the level of the upper border of thyroid cartilage [1,2]. The bifurcation level of CCA varies due to many factors such as genetic, embryological, stature, and environmental.

2009年8月26日 · To evaluate visibility of the external carotid artery (ECA) and its branches using three-dimensional (3D) balanced steady-state free-precession (SSFP) MR angiography with a time-spatial labeling inversion pulse (Time-SLIP), and …

As the ECA ascends the neck, it first curves slightly anteriorly, and then posteriorly as it courses toward the neck of the mandible, where it divides into its terminal branches: the superficial temporal and maxillary arteries.

2022年8月17日 · The external carotid artery’s size diminishes as it courses superiorly and gives off five branches along its journey before terminating at the parotid gland with its last two branches: the maxillary artery and the superficial temporal artery.
