Correct Answer » A Explanation |
 |
Anatomical Role
– Auriculotemporal nerve: Branch of the mandibular nerve (V3); supplies anterior-superior auricle (including tragus).
– Greater auricular nerve: Branch of cervical plexus (C2, C3); supplies lower and posterior parts, including lobule.
– Vagus nerve (auricular branch): Supplies concha and external auditory meatus.
– Lesser occipital nerve: (C2); supplies posterior-superior auricle.
Clinical Reasoning for the Correct Answer
– Region A (anterior-superior/tragus) → Auriculotemporal (V3).
– Region B (lobule/posterior-inferior) → Greater auricular (cervical plexus).
– Region C (concha/external meatus) → Auricular branch of vagus.
– Region D (posterior-superior) → Lesser occipital (C2).
