[2025-09-30T08:56:40.539903] [PI reasoning] **Checking ECA branches**

I need to confirm that external carotid artery (ECA) branches include the posterior auricular, occipital, and maxillary arteries. I found an article detailing eight typical branches, which is great for citation. Also, I’ll reference another article for clarity. For my answer, I’ll state: "D. Ophthalmic artery," explaining that it arises from the internal carotid artery, not the ECA. I’ll ensure to include my in-text citations for both sources.
