Question

To where do the anterior nasal wall veins drain?

Option 1: Superior ophthalmic vein
Option 2: Inferior ophthalmic vein
Option 3: Facial vein
Option 4: Olfactory bulb vein

Answer 1

The veins of the anterior nasal wall primarily drain into the facial vein, which is separate from the venous structures associated with the brain and eye.

Step-by-step explanation:

The veins of the anterior nasal wall primarily drain into the facial vein. The facial vein is responsible for draining blood from the superficial areas of the face, including the nasal region. While veins related to the brain, including the superior sagittal sinus, inferior sagittal sinus, cavernous sinus, and others, eventually lead to the jugular veins to return deoxygenated blood to the heart, the nasal veins are not part of this system. The other options, such as the superior and inferior ophthalmic veins, are concerned with draining areas related to the eye, and the olfactory bulb vein is not a standard anatomical term for any known venous structure.
