Maxillary nerve

Maxillary nerve (also known as the V2) is one of the three branches of the trigeminal nerve, which is the fifth cranial nerve. It comprises the intermediate division of the trigeminal nerve after it exits the skull through the foramen rotundum.

Etymology

The term "maxillary" is derived from the Latin word "maxilla" which means "jawbone". The term "nerve" comes from the Latin word "nervus" meaning "sinew, tendon, nerve".

Anatomy

The maxillary nerve is a sensory nerve that carries sensory information from the upper jaw, some parts of the nose, the palate, and the skin of the face. It does not carry motor fibers, unlike the mandibular nerve.

Branches

The maxillary nerve has several branches, including:

• Zygomatic nerve
• Infraorbital nerve
• Superior alveolar nerves
• Palatine nerves
• Nasopalatine nerve
• Pharyngeal nerve

Clinical significance

Damage to the maxillary nerve can result in loss of sensation in the areas it supplies. This can occur due to trauma, surgery, or in the context of certain diseases such as trigeminal neuralgia.
