Well, lets start with a pneumonic to memorize the names of the cranial nerves. I'll keep this one clean, although there are dirty ones.

1. Olfactory
2. Optic
3. Occulomotor
4. Trochlear
5. Trigeminal
6. Abducens
7. Facial
8. Auditory (Vestibulocochlear)
9. Glossopharyngeal
10. Vagus
11. Spinal Accessory
12. Hypoglossal
Cranial nerves are either motor, sensory, or both. There is a pneumonic for that.
Some say money matters but my brother says big boobs matter more.
S= sensory m= motor b= both
so...
Olfactory = sensory- sense of smell via olfactory bulbs through the cribiform plate of the ethmoid bone
optic = sensory- sight via the optic nerve
occulomotor = motor- most extrinsic eye muscles except superior oblique and lateral rectus, also constriction of pupil
trochlear = motor- motor to superior oblique muscle of eye
trigeminal = both- sensory to forehead, upper and lower teeth, cheeks- motor to muscles of mastication
abducens= motor- to lateral rectus muscle of eye
facial = both- sensory (taste ant 2/3 of tongue, submandibular gland)- motor to muscles of facial expression
auditory = sensory- hearing, to cochlea and vestibular canals
glosspharyngeal = both- motor to stylopharyngeus muscle only, sensory-taste post 1/3 of tongue, parotid gland
vagus = both- motor- pharyngeal muscles, laryngeal muscles, chest, abdominal contents, also sensory
spinal accessory = motor- to trapezius and sternocleidomastoid
hypoglossal = motor- extrinsic muscles of the tongue
This is a good summary. You also need to know the parasympathetic ganglion of the head. Ciliary ganglion, ptergygoid, otic, and submandibular. (This is top of my head, but I think these are the right names)
Also, remember that the sympathetic innervation of the head all comes from the superior sympathetic ganglion and travels with the various cranial nerves.
Hope this helps you. I know this is probably more than you need for your class, and the various things here apply to human anatomy. I didn't go into the various branches of the cranial nerves or the divisions of the trigeminal. Let me know if you need anything else.
