IX Glossopharyngeal
X Vagus
XI Accessory
XII Hypoglossal - CORRECT ANSWER list all cranial nerves in order
Olfactory and optic - CORRECT ANSWER list the sensory only nerves (no numbers needed)
Oculomotor, trochlear, abducens, Accessory, and Hypoglossal - CORRECT ANSWER list the motor only
nerves
Trigeminal, Facial, Vestibulocohlear, Glossopharyngeal, and vagus - CORRECT ANSWER list the nerves
that do both motor and sensory function
CN I Olfactory - CORRECT ANSWER Description of what nerve: Conducts olfactory sensations to brain
CN I Olfactory - CORRECT ANSWER What CN has the only type of nervous tissue to regenerate?
, Receptors in olfactory mucosa of nasal cavity - CORRECT ANSWER Origin of the Olfactory nerve
bipolar - CORRECT ANSWER what type of neurons are the receptors for the olfactory nerve
anosmia - CORRECT ANSWER Damage to the olfactory nerve causes what condition
Vision - CORRECT ANSWER sensory function of CN II Optic
CN II Optic - CORRECT ANSWER this special sensory nerve of vision if an outgrowth of the brain; more
appropriately called a brain tract
retina of the eye - CORRECT ANSWER origin of the optic nerve
anopsia - CORRECT ANSWER condition caused by damage to the optic nerve
anosmia - CORRECT ANSWER damage to the ethmoid bone may cause BLANK if it damages the nerve
receptors
sphenoid - CORRECT ANSWER the optic nerve passes through which bone via the optic foramen
CN III Oculomotor - CORRECT ANSWER This nerve innervates the upper eyelid muscle and four of the six
extrinsic eye muscles
supplies 4 extrinsic eye muscles to move eye and supplies levator palpebrae superioris muscle to elevate
eyelid - CORRECT ANSWER somatic motor function of CN III Oculomotor
superior rectus, inferior rectus, medial rectus, and inferior oblique - CORRECT ANSWER name the 4
extrinsic eye muscles included in the somatic function of the CN III oculomotor
innervates sphincter pupillae muscle of iris to make pupil constrict. Contracts cilliary muscles to make
lens of eye more spherical - CORRECT ANSWER Parasympathetic motor function of CN III Oculomotor
