What structure travels through foramen ovale?

• A. Vagus nerve
• B. Maxillary nerve
• C. Facial nerve
• D. Hypoglossal nerve

Answer: (B)

The maxillary nerve is the correct structure that travels through the foramen ovale. This foramen is a key opening in the skull located in the sphenoid bone, which serves as a passageway for important neurovascular structures.

The maxillary nerve, which is the second division of the trigeminal nerve (cranial nerve V2), exits the skull through the foramen ovale and supplies sensation to various regions of the face, particularly the midfacial area, including the cheeks, upper lip, and nasal cavity. This route is critical for the proper function of sensory perception in these areas.

In contrast, other options listed do not travel through this foramen. The vagus nerve primarily exits from the jugular foramen, the facial nerve exits through the internal acoustic meatus before traversing the stylomastoid foramen, and the hypoglossal nerve exits the skull via the hypoglossal canal. Understanding the specific paths of these nerves through various foramina in the skull helps clarify their anatomical relationships and functions in the cranial cavity.
