Question

Which nerve passes through the marked foramen in the given image:

• A. Lingual nerve
• B. Mandibular nerve
• C. Chorda tympani nerve
• D. Inferior alveolar nerve

Answer 1

The Correct Option is D

The question involves identifying a nerve that passes through a specific foramen, which is a natural opening, often in bones, that allows nerves or blood vessels to pass. In this instance, the foramen in question relates to dental or mandibular context.
The options provided are:

• Lingual nerve
• Mandibular nerve
• Chorda tympani nerve
• Inferior alveolar nerve

The inferior alveolar nerve is a branch of the mandibular nerve (which is the third branch of the trigeminal nerve, CN V3). It passes through the mandibular foramen, located on the internal surface of the ramus of the mandible, which then continues into the mandibular canal.
This nerve supplies sensation to the lower teeth and is the nerve typically anesthetized during dental procedures involving the lower jaw.
Therefore, the correct answer is the Inferior alveolar nerve, which matches the foramen marked in the given scenario.
