|
Definition
|
|
Term
| The parasympathetics involved with CN VII originate from what nucleus in the brain? |
|
Definition
| Superior salivatory nucleus |
|
|
Term
| The parasympathetics involved with CN VIII originate from what nucleus in the brain? |

|
|
Term
| The EW nucleus is in the _______ complex in the _____encephalon. The axons from here synapse in the _________ ganglion. |
|
Definition
| occulomotor, mesencephalon, ciliary |
|
|
Term
| Axons from the superior salivatory nucleus travel in which nerves (specifically), and synapse in which ganglia? |
|
Definition
| Greater petrosal and chorda tympani, pterygopalatine and submandibular |
|
|
Term
| Trace the preganglionic fibers from the inferior salivatory nucleus, to the gangion, and the postganglion fibers to the parotid gland. |
|
Definition
| Inf salivatory nucleus -> CN IX -> tympanic nerve -> tympanic plexus -> lesser petrosal nerve -> otic ganglion (synapse)-> hitch a ride on auriculotemporal to the parotid gland. |
|
|
Term
| Does the vagus nerve provide parasympathetic innervation to the head and neck? |
|
Definition
|
|
Term
| The ciliary ganglion is associated with what branch of V1? |
|
Definition
|
|
Term
| Which types of fibers travel through the ciliary ganglion WITHOUT synapsing? |
|
Definition
| Sensory and postganglionic sympathetics |
|
|
Term
| What types of fibers are contained in long ciliary nerves? Where do these long ciliary nerves come from? |
|
Definition
| Sympathetics and general sensory, the nasociliary nerve |
|
|
Term
| What types of fibers are contained in short ciliary nerves? |
|
Definition
| Parasympathic, sympathetic and general sensory |
|
|
Term
| Afferent axons from the retina that are involved in pupillary light reflexes terminate where? What do they bypass? |
|
Definition
| In the pretectal area and the superior colliculus. They bypass the LGN. |
|
|
Term
| The pupillary light reflex is testing what? What is the consensual reflex? |
|
Definition
| Testing parasympathetic innervation of the pupil. Consensual reflex is when the OTHER pupil also constricts. |
|
|
Term
| What happens to pupils during the accomodation reflex? Why? |
|
Definition
| While looking at a near object, pupils constrict bilaterally. Ciliary muscles contract to let lens thicken for near sight. |
|
|
Term
| Why does the consensual reflex happen? |
|
Definition
| Bilateral projections from the pretectal nucleus to the EW nuclei |
|
|
Term
| Why do fixed and dilated pupils occur? They indicate possible damage to what? |
|
Definition
| Unopposed action of dilator pupillae (sympathetic innervation), possible damage to EW nucleus in the brainstem |
|
|
Term
| What happens in presbyopia? |
|
Definition
| The lens loses flexibility and cannot thicken to focus on near objects. |
|
|
Term
| Nervus intermedius contains what types of fibers? |
|
Definition
| Sensory and preganglionic parasympathetics |
|
|
Term
| Chorda tympani contains what types of fibers? |
|
Definition
| Special sensory and parasympathetics |
|
|
Term
| The pterygoid canal runs through the ____________________ to the back wall of the pterygopalatine fossa. |
|
Definition
| Medial pterygoid plate of the sphenoid bone |
|
|
Term
| Otic ganglion is located in which fossa? |
|
Definition
|
|
Term
| The otic ganglion is located just deep to... |
|
Definition
|
|
Term
| Where is the ciliary ganglion in relation to the optic nerve and lateral rectus muscle? |
|
Definition
| Between the two, in the back of the orbit |
|
|
Term
| Where do sympathetics to the parotid gland come from? |
|
Definition
| The superior cervical ganglion -> external carotid artery |
|
|
Term
| The pterygopalatine ganglia is attached to V2 by what? |
|
Definition
| two pterygopalatine nerves |
|
|
Term
| Where is the submandibular ganglion located? |
|
Definition
| Medial to the mandible, suspended from the lingual nerve. |
|
|
Term

|
Definition
|
|
