Blood vessels of the parapharyngeal space

This video tutorial provides an in-depth exploration of the parapharyngeal space, focusing on the various blood vessels found in this region. It covers the brachiocephalic trunk, common carotid arteries, external carotid arteries, and their branches, including the superior and inferior thyroid arteries. The tutorial also discusses the occipital and ascending pharyngeal arteries, internal carotid arteries, and thyrocervical trunks. Additionally, it highlights the veins in the parapharyngeal space and concludes with resources for further learning.
