AEA means a number of things, in medical terms it refers to the anterior sieve artery, arachidonic acid aminoethanolamine, etc. Anterior Sial Artery: The anterior sial artery is one of the important blood vessels of the nose that emanates from the ophthalmic artery, passes through the anterior sial foramen of the orbital wall, traverses the medial orbital wall, and enters the anterior sial arterial canal of the sial sinus. In a few cases, the anterior sial artery travels outside the bony duct, and the vessel travels horizontally within the sial sinus in an anterior-inferior direction, penetrating the skull base at the apex of the sieve room to the anterior end of the olfactory fossa, and then passing through the foramen ovale toward the anterior wall of the nasal cavity, immediately adjacent to the middle turbinate. Aminoethanolamine arachidonic acid: is an endogenous cannabinoid neurotransmitter. It inhibits obesity, inflammation, pain and chemotherapy-induced nausea or vomiting by agonizing cannabinoid receptors CB1 and CB2, and may reduce symptoms of neurodegenerative diseases and multiple sclerosis. In addition, aminoethanolamine arachidonic acid has strong anti-tumor effects and can be used as a chemotherapeutic agent for tumor treatment.
