The cranial nerve exam is a type of neurological examination. It is used to identify problems with the cranial nerves by physical examination. It has nine components. Each test is designed to assess the status of one or more of the twelve cranial nerves (I-XII). These components correspond to testing the sense of smell (I), visual fields and ...

The cranial nerve exam allows directed tests of forebrain and brain stem structures. The twelve cranial nerves serve the head and neck. The vagus nerve (cranial nerve X) has autonomic functions in the thoracic and superior abdominal cavities. The special senses are served through the cranial nerves, as well as the general senses of the head and ...

Examination of the cranial nerves is an integral and important part of a complete neurological examination. Historically, these skills were crucial for diagnosing specific lesions. With the development of modern imaging modalities, the significance of clinical examination techniques has perhaps been undermined.
Examination of cranial nerves . A part of the neurological examination. Evaluate visual acuity and visual fields (CN II), extraocular movements (CNs III, IV, VI), facial sensation and muscle strength (CN V), facial movements (CN VII), audition (CN VIII), elevation of the soft palate and the uvula (CNs IX, X), trapezius and sternocleidomastoid contraction strength (CN XI), and movement of the ...

Conclusion: This paper illustrates that CN testing can be performed ...
It is important that clinicians have a sequence of their choosing that they use consistently. Components of the standard neurologic examination are found in Table 1 and discussed in detail in this review ( table 1 ). The text is adapted, with permission, from Reference 1 [ 1 ]. The examination of comatose patients is discussed separately.

Examination of the cranial nerves allows one to "view" the brainstem all the way from its rostral to caudal extent. The brainstem can be divided into three levels, the midbrain, the pons and the medulla. The cranial nerves for each of these are: 2 for the midbrain (CN 3 & 4), 4 for the pons (CN 5-8), and 4 for the medulla (CN 9-12).
It is a diencephalic derivative that develops from the optic stalk. The nerve ranges from 35 - 55 mm in length; with great variability between optic nerves in the same individual. The tubular structure begins at the ganglion cell layer of the retina and continues to the optic chiasma in the middle cranial fossa.
Cranial Nerve Assessment. Normal Response. Documentation. Hold a penlight 1 ft. in front of the client's eyes. Ask the client to follow the movements of the penlight with the eyes only. Move the penlight upward, downward, sideward and diagonally. Client's eyes should be able to follow the penlight as it moves.
