Final answer:
The supraorbital artery originates from the ophthalmic artery, which is a branch of the internal carotid artery responsible for supplying blood to the eyes.
Step-by-step explanation:
The origin of the supraorbital artery is the ophthalmic artery. The ophthalmic artery itself is a branch of the internal carotid artery that provides blood to the eyes. After the internal carotid artery enters through the carotid canal, it divides into several branches, including the anterior cerebral artery and the middle cerebral artery. These arteries supply blood to different parts of the cerebrum. The ophthalmic artery arises as a major branch of the internal carotid artery and supplies the eyes. Therefore, the correct answer to the student's question is that the supraorbital artery originates from the ophthalmic artery, which is a branch of the internal carotid artery.
