[TA]
a branch of the ophthalmic nerve [CN V1] in the superior orbital fissure, passing through the orbit, giving rise to the communicating branch to the ciliary ganglion, the long ciliary nerves, the posterior and anterior ethmoidal nerves, and terminating as the infratrochlear and nasal branches, which supply the mucous membrane of the nose, the skin of the tip of the nose, and the conjunctiva.

nasociliary nerve

usually the first branch of the ophthalmic nerve. It branches into the communicating branch with the ciliary ganglion; the long ciliary nerves, which are sensory to the eyeball but may also contain sympathetic fibers for pupillary dilation; the posterior ethmoidal nerve, which supplies the posterior ethmoidal air cells and the sphenoid sinus; the infratrochlear nerve, which distributes to the medial part of the upper and lower eyelids, the lacrimal sac, and the skin of the upper half of the nose; and the anterior ethmoidal nerve, which supplies the anterior cranial fossa, nasal cavity, and skin of the lower half of the nose.
