THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The ophthalmic artery also gives off the inferior and superior muscular vessels that supply the extraocular muscles. The supraorbital artery is also a branch of the ophthalmic artery and passes through the supraorbital foramen to supply the skin of the forehead and Levator palpebrae muscle.

Detailed explanation-2: -The vascular supply of the forehead is a compound system of arteries. The central region of the forehead is mainly vascularized by the supratrochlear artery and the supraorbital artery, which branches from the ophthalmic artery.

Detailed explanation-3: -Anterior Cerebral Artery (ACA): This vessel supplies blood to the front part of your brain, knows as your frontal lobe. There is a right sided ACA and a left sided ACA. If a stroke occurs in this area, you may see leg weakness and/or difficulty thinking and making decisions.

Detailed explanation-4: -The supratrochlear artery (or frontal artery) is one of the terminal branches of the ophthalmic artery. It arises within the orbit. It exits the orbit alongside the supratrochlear nerve. It contributes arterial supply to the skin, muscles and pericranium of the forehead.
