The 13th cranial nerve is often called the Vomeronasal nerve. It is forward of the olfactory nerve, and is thought to be associated with sexual behavior. Interestingly, this nerve is still found in whales, although their olfactory nerve has vanished in the course of evolution. It is also sometimes referred to as Nerve Zero because of its location.
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
The Vagus Nerve (V)
The Cranial Nerves that helps in shrugging of shoulder is the XI Cranial Nerve Nervus Accessorius or Accessory Nerve that innervated the Trapezius Muscle
VESTIBULO-COCHLEAR nerve which is 8th cranial nerve.
The vagus nerve is the 10th cranial nerve, also known as cranial nerve X.

Smell impulses are carried by the cranial nerve called the olfactory nerve (cranial nerve I). It is responsible for transmitting information about odors from the nose to the brain.
The optic nerve (cranial nerve II) is not involved in taste, as its primary function is vision. Taste is primarily mediated by the facial nerve (cranial nerve VII), glossopharyngeal nerve (cranial nerve IX), and vagus nerve (cranial nerve X).
