In the nerves of the peripheral nervous system; 12 cranial nerves and 31 spinal nerves.
There are different types of nerves in the human body namely: the cranial nerves, the spinal nerves, the sympathetic nerves, and the encephalon nerves just but to mention a few. Examples of these nerves includes: the optic nerve, the facial nerve, the vagus nerve, the thoracic nerve, and accessory nerve.
There are 31 pairs of spinal nerves in the human body.

There are approximately seven trillion nerves in the human body. There are twelve pairs of cranial nerves and thirty two pairs of spinal nerve roots which then branch out to the rest of the body.
cranial nerve I: olfactory:smell cranial nerve II:optic:vision cranial nerve III: oculomotor: 4 of 6 eye muscles cranial nerve IV: trochlear: cranial nerve V: Trigeminal cranial nerve VI: Abducens cranial nerve VII: Facial cranial nerve VIII: Vestibulochlear: hearing cranial nerve IX: Grosspharnxgeal: saliva formation cranial nerve X: Vegus cranial nerve XI: Acessory Spinal: trapizious movement cranial nerve XII: Hypoglosseal: toungue movement
Sharks have 12 pairs of cranial nerves. These nerves are responsible for functions such as vision, smell, and movement in sharks.
Your spinal cord
There are twelve pairs of cranial nerves in the human face that serve different functions such as sensory input, motor control, and autonomic control.
Each eye has one nerve for vision, the optic nerve, Cranial Nerve II. Nerves are actually bundles of many nerve fibers. There are nerves that supply impulses for the muscles associated with the eyeballs so they can move are the Cranial Nerve III, Oculomotor, Cranial Nerve IV, Trochlear, and Cranial Nerve VI, the Abducens nerve.
A nerve is a bundle of individual neurons. There are approximately 100 billion neurons in the human body (about the same number of stars in our Milky Way galaxy), but there are only 214 nerves in the human body.
The nerves in the human body can extend up to thousands of miles, as they are spread throughout the entire body and are interconnected to the brain and spinal cord.
