how does pain sensation (hint: touchy feely) from the tongue reach the brain? Bonus: how does taste reach the brain?
What is via the lingual branch of the mandibular branch of the trigeminal nerve (does GSE for ALL of the tongue) Bonus: Rostral 2/3 of the tongue send taste sensation via the CN 9 (glossopharyngeal) Cranial 1/3 of the tongue sends taste sensation via the lingual branch of the mandibular branch of the trigeminal nerve but then the SA fibers cross the chorda tympani to CN 7 and enters the brain via the facial nerve (CN 7)
100
Name the two components of the outer fibrous coat of the eye. Bonus: name their junction
What are the cornea and the sclera? Bonus: the cornea and sclera meat at the corneoscleral junction called the limbus
100
The aqueous humor is drained by a trabecular meshwork at this structure. Bonus: name what the humor drains into
What is the iridocorneal angle. Bonus: it enters the venous system via the venous scleral sinus
100
name the four muscles innervated by CN XI: the accessory nerve Bonus: what type of fiber innervates them?
What are: (1) trapezius (2) cleidocervicalis (3) sternocephalicus (4) omotransversarius Bonus: they are of branchiomeric origin and are innervated by special efferent nerves (SE)
100
Name the two ducts that empty into the caudal end of the mouth. Bonus: name where they empty
What is the parotid duct and the duct of the zygomatic salivary gland? Bonus: The parotid duct opens through the cheek on a small papilla located opposite the the caudal end of the upper fourth premolar. The duct of the zygomatic gland opens into the vestibule lateral to the last upper molar tooth
200
this nerve carries parasympathetic preganglionics (GVE) of the seventh nerve to the ptergopalantine ganglion for the innervation of the lacrimal gland and nasal mucosa
What is the major petrosal nerve
200
Name the three parts of the middle vascular coat of the eye. Bonus: name the middle vascular coat itself
What are the choroid, the ciliary body and the iris. Bonus: what is the uvea
200
this is a specialized layer of the choroid in which there is no pigment in the epithelial cells of the retina.
What is the tapetum lucidum
200
Name the cranial nerve that receives sensory information from the concave surface of pinna and external auditory canal (GSA)
What is What is the facial nerve (CN VII)
200
Name the two ducts that empty into the sublingual fold
What are the mandibular duct and the major sublingual duct
300
Name two nerve fiber types carried in the chorda tympani
What are: (1) taste SA from the tongue (going to the brain) and parasympathetic pregangionic (GVE) of CN 7 to manidibular and sublingual ganglions for salivary glands of the same names.
300
This is the posterior portion of the vascular coat and is firmly attached to the sclera. It lines the internal surface as far anterior as the ciliary body posterior to the lens. bonus: name the junction between this structure and the ciliary body
What is the choroid? Bonus: what is the ora serrata
300
This is the name for the fibers meshwork of the iridocorneal angle
What is the pectinate ligament?
300
this nerve receives sensory information (GSA) from skin of external auditory meatus / canal
What is CN 9: the glossopharyngeal
300
Which salivary gland has a small lymph node found along its rostral border? Bonus: name the lymph node
What is the parotid gland. Bonus what is the parotid lymph node.
400
Nerve fibers pass through the otic ganglion to regulate these two glands
What are the parotid and zygomatic salivary glands
400
This is the suspensory apparatus of the lens. Bonus: name the fibers it is composed of and from what it is suspended
What is the zonule? Bonus: what are zonular fibers and the ciliary body
400
This structure of the external ear is a thick, quadrangular plate that sits opposite the anthelix.
What is the tragus?
400
This gland is located near the lymph nodules on the bulbar conjunctival surface.
What is the superficial gland of the third eyelid.
400
This lymph node is dorsal to the common carotid artery at the level of the larynx
What is the medial retropharyngeal lymph node.
500
This ganglion lies below the maxillary branch of the trigeminal nerve. It carries nerve fibers to the lacrimal gland and nasal mucosal glands.
What is the ptergopalatine ganglion?
500
the space between the cornea and the lens is divided into two chambers by this structure. Bonus: name the chambers and their respective boundaries
What is the iris? Bonus: the anterior chamber is bounded by the cornea and the iris. The posterior chamber is bounded by the iris and lens
500
This is the cartilaginous plaque attached at the level of the medial angle of the eye to the wall of the orbit.
What is the trochlea?
500
This is the name for the location where the superior and inferior palpebrae meet.
What is a commissure? (medial and lateral commissure)
500
Name the four salivary glands and the location of their ducts
What are: (1) parotid gland; duct empties into mouth at upper 4th premolar (2) zygomatic gland: duct empties into mouth at last molar (3) sublingual gland: duct empties into the sublingual fold (4) mandibular salivary gland: duct empties into the sublingual fold
