eimsori [14]

Answer:

Cranial Nerves:

The cranial nerves are the set of 12 pairs of nerves which are originated from the brain. As they are responsible for some of the essential functions , such as vision, smell, and balance of the human body structure.

The 12 pairs of the cranial nerves are as as under:

The olfactory nerve
The optic nerve
The oculomotor nerve
The trochlear nerve
The trigeminal nerve
The abducens nerve
The facial nerve
The vestibulocochlear nerve
The glossopharyngeal nerve
The vagus nerve
The spinal accessory
The hypoglossal nerve,

It is very hard for the students to remember all the names of the cranial nerves as we can just recall them by memorizing the device-Old Opie Occasionally Tries Trigonometry And Feels Very Gloomy, Vague And Hypoactive.

Explanation:

Optic chasma:

The optic chasma originates as one of the cranial nerves, as it serves for the function of vision sense in human body. The nerves are responsible for carrying the set of information and data from the retina of the eye to the brain. As the communication between the two regions or part of the body, as they hold the capacity to carry the charges or information from the retina of the eye towards the brain.
