Parts of the trigeminal nerve: Are found within the following: foramen ovale, foramen rotundum, & optic canal Transmit motor information only through its ophthalmic and maxillary branches Provide motor input to the muscles of facial expression Provide sensory information from the brain to the teeth None of the above are correct
Added by Robert J.
Step 1
The trigeminal nerve has three branches: the ophthalmic (V1), maxillary (V2), and mandibular (V3) branches. The ophthalmic branch passes through the superior orbital fissure, the maxillary branch passes through the foramen rotundum, and the mandibular branch Show more…
