Correct answer: A — Mandibular foramen on the medial surface of the ramus
The inferior alveolar nerve (branch of V3) enters the mandibular foramen on the medial surface of the mandibular ramus. It runs through the mandibular canal supplying the lower teeth. It exits as the mental nerve through the mental foramen below the second premolar. Inferior alveolar nerve block is performed by depositing LA near the mandibular foramen (Halsted approach).
