Detailed explanation-3: -The supraorbital artery is a branch of the ophthalmic artery supplying part of the orbit and face.

Detailed explanation-4: -The branches of the ophthalmic artery-dorsal nasal artery, supratrochlear artery, and supraorbital artery-are responsible for the nutrition of the forehead. These arteries are connected with those lying next to them. Additionally, they all anastomose with the frontal branch of the superficial temporal artery.
