Modalities Functions Each type of cranial nerve either have sensory functions motor functions or both. The types of information that cranial nerves transport can all differ.

There are seven types of modalities of information that can be sent with three of these being unique to cranial nerves. General visceral sensory GVS this is general sensation from internal organs. The major function of Cranial nerves is to send and receive information from the brain to the various body parts.

They operate in the head and neck region of the body. Classification of Cranial Nerves Every cranial nerve CN is assigned a Roman numeral as a name. The numbering is based on the order in which the CN emerges from the brain from ventral to dorsal.

The name indicates the function or the course. List of CNs I Olfactory II Optic III Oculomotor IV Trochlear V Trigeminal VI Abducens VII Facial VIII Vestibulocochlear. The 12 Cranial NervesDetail Cranial Nerve 1 Sensory nerve Olfactory Nerve controls sense of smell Cranial Nerve 2 Sensory nerve- Optic Nerve- controls vision by sending information from retina Cranial Nerve 3 Motor nerve- Oculomotor Nerve-Controls most eye.

Cranial nerves carry information from the brain to other parts of the body primarily to the head and neck. These nerves are paired and present on both sides of the body. They are mainly responsible for facilitating smell vision hearing and movement of muscles.

Cranial nerves are concerned with the head neck and other facial regions of the body. Cranial nerves arise directly from the brain in contrast to. Cranial nerves are the 12 nerves of the peripheral nervous system that emerge from the foramina and fissures of the cranium.

Their numerical order 1-12 is determined by their skull exit location rostral to caudal. All cranial nerves originate from nuclei in the brain. The nerves attached to the brain are the cranial nerves which are primarily responsible for the sensory and motor functions of the head and neck one of these nerves targets organs in the thoracic and abdominal cavities as part of the parasympathetic nervous system.

There are twelve cranial nerves which are designated CNI through CNXII for Cranial Nerve using Roman numerals for 1 through 12. Preganglionic parasympathetic to. Pterygopalatine ganglia innervates lacrimal gland nasal glands and palatine glands.

Pharynx palate carotid sinus carotid body and posterior 13 tongue. All tongue muscles these end in glossus are innervated by CN12 except palatoglossus. The cranial nerves provide afferent and efferent sensory motor and autonomic innervation to the structures of the head and neck.

Unlike spinal nerves whose roots are neural fibers from the spinal grey matter cranial nerves are composed of the neural processes associated with distinct brainstem nuclei and cortical structures. While the spinal grey matter is organized into a. CN 0 Terminal.

On the chart below you will see 4 Columns Vertebral Level Nerve Root Innervation and Possible Symptoms. C1-C7 is the NECK T1-T12 is the UPPER BACKrib cage area and. L1-L5 is the LOWER BACK.

Simply line up the Vertebral Level with the Possible Symptoms and you will see some surprising connections of symptoms that. In the section on the cranial nerves we have articles on each of the 12 cranial nerves. In the first we discuss the olfactory nerve detailing its function and describing the anatomy of this important nerve for the sense of smell.

The second cranial nerve is the optic nerve which is responsible for relaying sight back. The cranial nerves are twelve pairs of nerves from the central nervous system. The cranial nerves are loosely based on their functions.

In this summary we discuss the nomenclature of the cranial nerves and supply some background information that might make it easier to understand the nerves and their function. This summary should read alongside the complete articles for each of the cranial.
