1. Lacrimal
2. Frontal 3. Nasociliary |
|
|
Where does the lacrimal nerve go to (3 places)?
|
1. Lacrimal gland
2. Skin of upper eyelid (lateral part) 3. Conjunctiva (lateral part) |
|
|
What is the route of the lacrimal nerve?
|
Between lateral rectus muscle and roof of orbit.
|
|
|
What are the 3 branches of the Frontal Nerve?
|
1. Supratrochlear
2. Supraorbital 3. Nerve to the frontal sinus |
|
|
Where does the Supratrochlear nerve go (3 places)?
|
1. Forehead (lower/mid part)
2. Skin of upper eyelid (medial part) 3. Conjunctiva (medial part) |
|
|
What is the route of the supratrochlear nerve?
|
Runs deep to periorbita, and superficial to levator palpebrae
|
|
|
Where does the Supraorbital nerve go (3 places)?
|
1. Forehead (lateral part)
2. Scalp (front) 3. Conjunctiva (central part) |
|
|
What is the route of the Supraorbital nerve?
|
Through the supraorbital notch (foramen).
|
|
|
What does the Nerve to Frontal Sinus innervate?
|
The mucosa of the frontal sinus.
|
|
|
What are the 5 branches of the Nasociliary nerve?
|
1. Ant/post ethmoidal nerves
2. Infratrochlear nerve 3. Meningeal nerve 4. Long ciliary nerve 5. Short ciliary nerve |
|
|
What is the route of the nasociliary nerve in general?
|
It runs within the muscular cone and tendinous ring, crosses the optic nerve with the opthalmic artery.
|
|
|
What 3 areas are innervated by the Anterior/posterior ethmoidal nerves?
|
1. Mucosa of nasal cavity
2. Anterior ethmoidal and frontal sinuses 3. Posterior ethmoidal and sphenoid sinuses |
|
|
What are the 2 branches of the anterior/posterior ethmoidal nerves? What do they innervate?
|
1. Internal nasal nerves - to mucosa of nasal septum
2. External nasal nerves - to tip of nose |
|
|
What 3 things are innervated by the infratrochlear nerve?
|
1. Upper eyelid (medial part)
2. Root of nose 3. Lacrimal sac |
|
|
What does the meningeal nerve innervate?
|
Supratentorial parts of the dura
|
|
|
What does the long ciliary nerve innervate?
|
The dilator pupillae with sympathetic fibers
|
|
|
What does the short ciliary nerve innervate?
|
The sphincter pupillae with parasympathetic fibers
|
|
|
Is the Lacrimal nerve purely sensory like the rest of the opthalmic nerve V1?
|
not completely; it carries postganglionic parasympathetic secretoMOTOR fibers of CN VII from the pterygopalatine ganglion to lacrimal gland.
