What are the innervation of the eye?
Cranial nerve #2 - optic nerve - special sensory for vision Cranial nerve #3 - occulomotor nerve - motor for extraoccular muscles & parasympathetic to ciliary ganglion Cranial nerve #4 - trochlear nerve - motor for extraoccular muscle (superior oblique) Cranial nerve #6 - abduscens nerve - motor for extraoccular muscle (lateral rectus)
Where do the cranial nerves exit?
The cranial nerves exit from the brainstem. They emerge from specific openings in the skull called foramina, which are small bony passageways. These openings provide a pathway for the cranial nerves to exit the skull and innervate different parts of the head and neck.
What is the difference between peripheral nerves and cranial nerves?

What reflex is centered in the brain and involves cranial nerves?
The reflex that is centered in the brain and involves cranial nerves is the cranial reflex. An example of this is the pupillary light reflex, where light exposure causes the pupils to constrict. This reflex involves the optic nerve (Cranial Nerve II) for sensing light and the oculomotor nerve (Cranial Nerve III) for pupil constriction. The processing occurs in the brainstem, illustrating the integration of sensory and motor functions.
