Cranial nerves are categorized as a part of the peripheral nervous system. The 12 pairs of cranial nerves exit from the brain, are numbered sequentially from anterior to posterior, and pass through foramina to reach their destinations. The nerve's name sometimes indicates the structure it innervates or its function. The names of the cranial

The Cranial Nerves - TSDocs

THE CRANIAL NERVES (Origin, Pathways & Applied Anatomy) There are twelve cranial nerves, which leave the brain and pass through foramina in the skull. All the nerves are distributed in the head and neck except the tenth, which also supplies structures in the thorax and abdomen. The cranial nerves are named as follows; I. Olfactory II. Optic III.

o Cranial nerves are one way to tell the brain what is going on in the body. There are twelve pairs of cranial nerves in the brain. The senses (eyes, ears, etc.) are connected to cranial nerves.

They are called cranial nerves because they emerge through foramina or fissures in the cranium and are covered by tubular sheaths derived from the cranial meninges. There are twelve pairs of cranial nerves, which are numbered I to XII, from rostral to caudal, according to their attachment to the brain and penetration of the cranial dura.

are the 12 cranial nerves, which connect directly to the brain, as shown in 10th Martini Figure 14-19 (Origins of the Cranial Nerves). The cranial nerves are numbered from 1 to 12 using Roman numerals. Roman numerals are easy to handle if you know three simple rules: I stands for 1, V stands for 5, X stands for 10, L stands for 50, etc.
