What is the function of cranial nerve CN VIII?
This cranial nerve has a vestibular part, which functions in balance, equilibrium, and orientation in three-dimensional space, and a cochlear part, which functions in hearing.
How do you remember the functional components of the cranial nerves?

- O: olfactory nerve (CN I)
- O: optic nerve (CN II)
- O: oculomotor nerve (CN III)
- T: trochlear nerve (CN IV)
- T: trigeminal nerve(CN V)
- A: abducens nerve (CN VI)
- F: facial nerve (CN VII)
- A: auditory (or vestibulocochlear) nerve (CN VIII)
What is the 8th nerve?
The vestibulocochlear nerve, also known as cranial nerve eight (CN VIII), consists of the vestibular and cochlear nerves. The vestibular nerve is primarily responsible for maintaining body balance and eye movements, while the cochlear nerve is responsible for hearing.
How do you remember the spinal nerves?
A useful mnemonic for remembering the relationships in the spinal cord is: SAME-DAVE (sensory-afferent, motor-efferent; dorsal-afferent, ventral-efferent). In the thoracic region, the upper lumbar region and in segments of the sacral region of the spinal cord, there is also a lateral horn of gray matter.
What is a mnemonic for the 12 cranial nerves?

What is an example of mnemonic?
Songs and jingles can be used as a mnemonic. A common example is how children remember the alphabet by singing the ABCs. The first letter of each word is combined into a new word.
Is there a mnemonic to remember the names of cranial nerves?
There are several mnemonics available that outline the names of cranial nerves as well as they are built in such a way that you can easily remember the sensory and motor functions of all cranial nerves. We have compiled all possible mnemonics for you. So, you don’t have to. Just memorize a few of them or even single will do.
What is the function of the cranial nerve VIII?
Cranial nerve VIII, concerned with hearing and equilibrium, is traditionally classified as sensory, but it also has motor fibers that return signals to the inner ear and tune it to sharpen the sense of hearing. The nerves traditionally classified as mixed have sensory functions quite unrelated to their motor functions.
Where do the 12 pairs of cranial nerves originate?
The 12 pairs of cranial nerves originate from the nose (CN I), the eyes (CN II), the inner ear (CN VIII), the brainstem (CN III-XII) and the spinal cord (part of XI). Cranial nerves have sensory (afferent) and motor (efferent) functions.
Which is the mnemonic for remembering functional information?
Remembering functional information: Ooh, Ooh, Ooh, to touch and feel very good velvet. Such heaven! If you write out the mnemonic for remembering the names next to the mnemonic for their function then they will align giving you an easier way to remember both the cranial nerve names and their function.
