ONES IN BOLD ARE MOTOR (3,4,6,11,12) are motor
Cranial nerves I, II, and VIII are purely sensory, so the remaining 9 nerves are both sensory and motor.

The levator palpebrae muscle is primarily responsible for opening the eyelids, it is innervated by cranial nerve 3 (occulomotor nerve). Raising the eyebrows, which will also open the eyes wider and may be what you are asking about, is done by occipitofrontalis. This muscle is innervated by cranial nerve 7 (facial nerve).
Actually, there are three cranial nerves that are completely sensory: Olfactory nerve, Optic nerve and the Vestibulocohlear nerve. The Optic nerve is responsible for sensory information for vision, the Olfactory nerve is responsible for sensory information coming from the nose and the Vestibulocohlear (the craziest word to spell) involves sensory information for hearing (get it?- cohlear, ear) and equilibrium.
A doctor who specializes in disorders of the nerves is called a neurologist; this individual also often deals with disorders of the brain (which is basically a big collection of nerves).

No. Biology is the science that deals primarily with living things.
Some examples of a unit of government that deals with a specific function are: transportation department and water department.

Article II of the Constitution
It deals with central vision.
The branch of the life sciences which deals with the structure and function of the nervous system is called neuroscience.
