3 sty 2012 · There are 12 cranial nerves, each with specific functions. They are numbered I through XII based on their position from the front to the back of the brain. Below is a chart of the 12 cranial nerves, the assessment technique used, if the response elicited is normal, and how to document it.
Question 1: Which way does the tongue deviate in a XII nerve lesion? Question 2: Which way does the uvula deviate in a X nerve lesion? Question 3: What are the afferent and efferent pathways of the gag reflex? Question 4: What are clinical signs of cavernous sinus syndrome? Question 5: What is Lateral Medullary Syndrome? Question 6:
Extraocular movements controlled by these nerves are tested by asking the patient to follow a moving target (eg, examiner’s finger, penlight) to all 4 quadrants (including across the midline) and toward the tip of the nose; this test can detect nystagmus and palsies of ocular muscles.

20 maj 2024 · The hypoglossal nerve (CN XII) is exclusively a motor nerve carrying general somatic efferent fibers (GSE). It innervates all intrinsic and almost all extrinsic muscles of the tongue, as well as one suprahyoid muscle, the geniohyoid muscle.
12 kwi 2019 · Cranial nerve XII is the hypoglossal nerve, a somatic motor nerve so named for its literal translation of “under” and “tongue.” In this article, we discuss the structure and function of the hypoglossal nerve, before describing the clinical relevance of this nerve.
7 lis 2022 · Introduction. The hypoglossal nerve is the 12th cranial nerve (CN XII). It is mainly an efferent nerve for the tongue musculature. The nerve originates from the medulla and travels caudally and dorsally to the tongue (see Image. The Hypoglossal Nerve). Go to: Structure and Function.
