Which branch of the zygomatic nerve supplies the skin over the temple?

Explanation:
The skin over the temple is supplied by the zygomaticotemporal branch, a cutaneous branch of the zygomatic nerve (from the maxillary division, V2). As the zygomatic nerve crosses the zygomatic arch, the zygomaticotemporal branch runs anteriorly into the temple region to innervate the overlying skin. The zygomaticofacial branch supplies the cheek area over the zygomatic bone, not the temple; the infraorbital nerve (another V2 branch) serves the lower eyelid, cheek, and upper lip, but not the temple; and the nasociliary nerve (from V1) serves the nose and medial eye region. Therefore, the temple skin is innervated by the zygomaticotemporal branch.
