maxillary vein การใช้

• The pterygoid plexus of veins becomes the maxillary vein.
• The maxillary vein and the superficial temporal vein later join to become the retromandibular vein.
• It then crosses the posterior root of the zygomatic arch, enters the substance of the parotid gland, and unites with the internal maxillary vein to form the posterior facial vein.
