What are the first 12 cranial nerves?
The 12 cranial nerves include the:
- olfactory nerve.
- optic nerve.
- oculomotor nerve.
- trochlear nerve.
- trigeminal nerve.

Are there 10 or 12 cranial nerves?
The cranial nerves are a set of 12 paired nerves in the back of your brain. Cranial nerves send electrical signals between your brain, face, neck and torso. Your cranial nerves help you taste, smell, hear and feel sensations. They also help you make facial expressions, blink your eyes and move your tongue.
What are the cranial nerves in order?
Cranial nerve function
- I. Olfactory nerve. The olfactory nerve sends sensory information to your brain about smells that you encounter.
- II. Optic nerve.
- III. Oculomotor nerve.
- IV. Trochlear nerve.
- V. Trigeminal nerve.
- VI. Abducens nerve.
- VII. Facial nerve.

Where are the 12 cranial nerves located?
Their numerical order (1-12) is determined by their skull exit location (rostral to caudal). All cranial nerves originate from nuclei in the brain. Two originate from the forebrain (Olfactory and Optic), one has a nucleus in the spinal cord (Accessory) while the remainder originate from the brainstem.

Where do the 12 cranial nerves originate?
All the cranial nerves originate from nuclei in the brain. Two of the cranial nerves, the optic nerve and the olfactory nerve, originate from the cerebrum. The accessory nerve has a nucleus in the spinal cord. The rest of the cranial nerves originate from the brain stem.

Trochlear nerve
Trochlear nerve is the smallest cranial nerve. Out of the 12 pairs of cranial nerves, the fourth paired cranial nerve, the trochlear nerve is the smallest of all by virtue of the number of axons.
What is the shortest cranial nerve?
The olfactory nerve is the first cranial nerve and conveys special sensory information related to smell. It is the shortest of the cranial nerves and passes from its receptors in the nasal mucosa to the forebrain.
