| | Cranial nerves - Wikipedia, the free encyclopedia |
 | | Cranial nerves are nerves that emerge from the brainstem instead of the spinal cord. | | | Human cranial nerves are evolutionarily homologous to those found in many other vertebrates. | | | Although twelve nerves are classically described in humans, there is a theory that finds favour with some authors, that humans really have thirteen cranial nerves (Andy Lelli, 1999). |

| | Spinal Cord and Cranial Nerves |
| | Any nerves which exit the bones of the CNS (spinal nerves and cranial nerves) are considered part of the peripheral nervous system (PNS). | | | The ventral nerve root is composed of efferent, or motor, fibers that arise from cell bodies located in the ventral and lateral columns of the gray matter of the spinal cord. | | | The overlapping of adjacent dermatomes is not the same for all of the cutaneous sensations; the overlap is greater for touch than it is for pain and temperature. |

| | The Precise Neurological Exam |
| | If there is a lesion in the brainstem involving a cranial nerve nucleus along with other areas of the brain stem, then the lesion is considered both central and peripheral. | | | Once this is done, ask the patient to shrug their shoulders as strong as they possible can while the examiner resists this motion by pressing down on the patient's shoulders with their hands. | | | Some clinicians omit testing for the gag reflex unless there is dysarthria or dysphagia present by history or examination, or if cranial nerve palsies are present at the medullary level. |

| | You will probably develop your own approach to remembering the cranial nerves and their branches and what they do but this is one method to consider. | | | You sort of have to memorize which nerves have motor or sensory or both modalities, then consider what part of the head and neck is involved with each nerve. | | | A modality is sensory, motor, special sensory, etc. Below is a breakdown of the modalities of cranial nerves. |

| | There are twelve pairs of cranial nerves; they are attached to the brain and are transmitted through foramina in the base of the cranium. | | | The sensory or afferent cranial nerves arise from groups of nerve cells outside the brain; these nerve cells may be grouped to form ganglia on the trunks of the nerves or may be situated in peripheral sensory organs such as the nose and eye. | | | The motor or efferent cranial nerves arise within the brain from groups of nerve cells which constitute their nuclei of origin. |
