The lacrimal bones are two small and fragile bones of the facial skeleton; they are roughly the size of the little fingernail and situated at the front part of the medial wall of the orbit.

The lacrimal nerve branches from the ophthalmic nerve immediately before traveling through the superior orbital fissure to enter the orbit. [citation needed]At the superior portion of the lateral wall of the orbit, it also receives a secretomotor [2]: 495 communicating [2]: 402 parasympathetic [3] branch from the zygomaticotemporal nerve [2]: 495 for the lacrimal gland.

Bone pain originates from both the periosteum and the bone marrow which relay nociceptive signals to the brain creating the sensation of pain. Bone tissue is innervated by both myelinated (A beta and A delta fiber) and unmyelinated sensory neurons. In combination, they can provide an initial burst of pain, initiated by the faster myelinated ...
