|
Name: Optic
Type: Sensory (special sensory) Route: Optic canal (w/opthalmic artery) location: in the sphenoid bone between the body and the two roots of the lesser wing SSA |
|
|
What is the name, type, route and location of Cranial Nerve III?
what does it supply? |
Name: Oculomotor
Type: Motor &(Parasympathetic to ciliary ganglion that goes to pupil) (GVE) Route: Superior Orbital Fissure, between the lesser and greater wings location: crosses on top of optic tract before (optic nerve chiasma) supplies: 5 muscles (GSE) -levator palpebrae -superior rectus -medial rectus -inferior rectus -inferior oblique GSE,GVE,GSA |
|
|

what does it supply? |
Name: Trochlear
Type: Motor Route: Superior Orbital Fissure location: from posterior side of brainstem then runs right by V supplies: superior oblique muscle GSE,GSA |
|
|
is the name, type and route of Cranial Nerve V?
|
Trigeminal
Type: Mixed (sensory & motor) Route: Superior Orbital Fissure (V1), Foramen Rotundum (V2), Foramen Ovale (V3) GSA SVE(this is the motor part) |
|

|
|
What is the name, type, route and location of Cranial Nerve VII?
|
Name: Facial
Type: Mixed (special sensory, sensory, motor and parasympathetic) Route: Internal Auditory Meatus location: anterior to VIII,top lateral portion of medulla SVE,GVE,SVA,GSA |

|
What is the name, type, route and location of Cranial Nerve VIII?
|
Name: Vestibulomotor/Vestibulocochlear
Type: Sensory (special sense for hearing and balance) Route: Internal Auditory Meatus location: runs with facial nerve -really two parts to this nerve vestibular(balance) and cochlear (hearing) SSA |
|
|
What is the name, type, route and location of Cranial Nerve IX?
|
Name: Glossopharyngeal
Type: Mixed (special sensory, sensory, motor and parasympathetic) Route: Jugular foramen location: medulla just inferior of VII and VIII SVE,GVE,SVA,GSA,GVA |
|
|
Name specifics of IX nerve
special sensory, sensory, motor and parasympathetic |
-taste to posterior 1/3 SVA
-sensory to 1/2 of pharyngeal wall GSA -motor to stylopharyngeus muscle SVE -parasympathetic supplies secretory fibers through otic ganglion to parotid gland GVE -GVA from carotid bodies |
|
|
what is the name, type, route and location of Cranial Nerve X
|
XName: Vagus
Type: Mixed (special sensory, sensory, motor, and parasympathetic) Route: Jugular foramen location: arises as a group of rootlets on the anterolateral surface of the medulla oblongata just inferior to the rootlets arising to form the glossopharyngeal nerve [IX] SVE,GVE,SVA,GSA,GVA |
|
|
What is the name, type, route and location of Cranial Nerve XI?
|
Name: Accessory
Type: motor (the sternocleidomastoid and trapezius muscles) Route: enters at foramen magnum and exits at Jugular foramen (enters to exit) location: its roots arise from motor neurons in the upper five segments of the cervical spinal cord SVE,GSE,GSA |
|
|
What is the name, type, route and location of Cranial Nerve XII?
|
Name: Hypoglossal
Type: Motor Route: Hypoglossal canal location: arises as several rootlets from the anterior surface of the medulla (medial to 7-10) GSE,GSA |
|
|
specifics of X
special sensory, sensory, motor, and parasympathetic |
-special sensory, taste buds at epiglottis
-sensory, outer surface of eardrum, external aucoustic meatus, back of auricle -motor, to larynx, pharynx, and palate -parasympathetic, motor innervation of minor slaivary glands, GI, heart etc... |

|
mnemonic for cranial nerves
|
On Occasion Our Trusty Truck Acts Funny. Very Good Vehicle Any How.
|
|
|
mnemonic to remember the types of information cranial nerves carry (sensory, motor, or both)
|
Some Say Marry Money, But My Brother Says Big Butts Matter More
|
|
|
four nerves that are parasympathetic
|
III, VII, IX, X
these are GVE |
|
|
three cranical nerves that carry special sense only
|
I, II, VIII
|
|
|
three cranial nerves that carry all four types of nerves
|
VII, IX, X
|
|
|
which component corresponds to parasympathetic innervation
|
GVE
-they cause secretion |
|
|
which component corresponds to proprioception
|
GSA (general somatic afferent)
3,4,5,6,7,9,10,11,12 -everything not special(1,2,8) -associated with somatic and cranial nerves that are sensory. Touch, pressure, temp, pain, proprioception |
|
|
if a nerve has a GSE component it will have what other component?
|
GSA (general somatic afferent)
-except 9 and 10 they have GSA but NO GSE |
