cranial nerve3
VAGUS
The second cranial nerve is the optic nerve.
The nerves involved in diplopia include three cranial nerves: the oculomotor nerve (third cranial nerve), the abducens nerve (sixth cranial nerve), and the trochlear nerve (fourth cranial nerve).
Cranial nerve 4 (IV) is the trochlear nerve.

Cranial Nerve V
The vestibulocochlear nerve innervates the ear.
Vagus nerve (CN 10) innervates your thoracoabdominal viscera by the parasympathetic nervous system.
The vestibulocochlear nerve or cranial nerve 8 (CN8) is largely involved with listening to music. However the trigeminal nerve (CN5), which innervates the tensor tympani, and the facial nerve (CN7), which innervates the stapedius muscle, may alter the perception of sound and theoretically affect the perception of music.

The Vagus Nerve
The vagus nerve is the tenth cranial nerve. It is considered as one of the most important of all the twelve cranial nerves. These twelve cranial nerves, the vagus nerve included, emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column. The vagus nerve originates in the medulla oblongata, a part of the brain stem.
he trochlear nerve (the fourth cranial nerve, also called the fourth nerve, IV) is a motor nerve (a "somatic efferent" nerve) that innervates a single muscle: thesuperior oblique muscle of the eye.The trochlear nerve is unique among the cranial nerves in several respects. It is the smallest nerve in terms of the number of axons it contains.
The optic nerve (purely sensory; carry afferent impulses for vision) Oculomotor (innervates four of the extrinsic eye muscles) Trochlear (innervates an extrinsic eye muscle that hooks through a pulley-shaped ligament in the orbit) Abducens (innervates the muscle that turns abducts the eyeball)

opthalmic nerve is the brach of trigerminal nerve. It innervate the sensory on your forehead. It also innervates the structure inside the skull such as the tentorium cerebelli, falx cerebri and part of the anterior cranial fossa.
