Rarely evaluated in clinical practice. The following tests are done to assess cranial nerves and nerves involved in the response or reflex; afferent (A) and efferent (E) nerves are listed. menace response (Figure 1): A: CN II (retina); E: CN VI, CN VII; in addition, the thalamus, cerebrum, and cerebellum are involved in the response and its pathway
11 wrz 2016 · This latter reflex involves stimulating the maxillary region (CN V) and observing for a blink (CN VII). The facial nerve also supplies sensory innervation to the inner pinna, so this region can be lightly stimulated (e.g., hemostat tips) and the patient observed for a behavioral response.
The neurological examination is the most fundamental tool that neurologists use to identify and isolate problems in the central and peripheral nervous system (CNS & PNS).
The brainstem contains the cranial nerve cell bodies (except CN I and II). The midbrain contains the reflex center for vision and hearing (colliculi) and the nuclei of CN III and IV. The pons lies between the midbrain and medulla oblongata and contains the nucleus of CN V.
