Question

Which cranial nerves are included in the assessment for dysphagia in a patient diagnosed with Guillain-Barré syndrome?

a) Cranial Nerve I (Olfactory)
b) Cranial Nerve VII (Facial)
c) Cranial Nerve X (Vagus)
d) Cranial Nerve XII (Hypoglossal)

Answer 1

The assessment of dysphagia in Guillain-Barré Syndrome involves Cranial Nerve VII (Facial) for taste and salivation, Cranial Nerve IX (Glossopharyngeal) for taste and the gag reflex, and Cranial Nerve X (Vagues) for motor control of swallowing.

Step-by-step explanation:

The cranial nerves included in the assessment for dysphagia in a patient diagnosed with Guillain-Barré Syndrome are Cranial Nerve VII (Facial), Cranial Nerve IX (Glossopharyngeal), and Cranial Nerve X (Vagues). The Cranial Nerve VII is involved in taste sensation in the anterior two-thirds of the tongue as well as salivation. The Cranial Nerve IX contributes to taste sensation in the posterior one-third of the tongue and is responsible for the gag reflex, which is relevant for swallowing. The Cranial Nerve X plays a crucial role in the motor function of swallowing by innervating muscles in the pharynx and larynx. Although not directly related to dysphagia, Cranial Nerve XII (Hypoglossal) is important for the movements of the tongue.
