the nasocilliary gives off a branch to the ciliary ganglion. in the ciliary gangion it gives off long ciliary nerves (sensory to the eiyeball) but also conatins what type of fibres? to waht nerves does the nasociliary nerve give rise to 3 ?what to tehy supplz?
sympathetic fibres for pupil dilation before continuing
posterior and then an anterior ethmoidal nerve and terminates as the
infratrochlear nerve.
The posterior ethmoidal: nerve exits the orbit via the posterior ethmoidal foramen and carries sensation from the posterior ethmoidal air cells and spenoid sinus.
The anterior ethmoidal nerve: exits the orbit via the anterior ethmoidal foramen and receives sensation from the anterior cranial fossa, nasal cavity and the skin over the lower half of the nose,
infratrochlear nerve: exits the orbit medially and receives sensation from the medial part of the upper and lower eyelids, the
lacrimal sac and skin of the upper half of the nose.
