People suspected of having a stroke can be asked to stick their tongues straight out. A slanted or somewhat bent tongue may be just one indicator of stroke. Determine the cranial nerve affected if the tongue is bent or slanted and identify the nerve as
sensory, motor, or mixed. Describe the function of this nerve.
What will be an ideal response?
The affected nerve if the tongue is bent or slanted during a stroke is the hypoglossal nerve (XII). The hypoglossal nerve is a motor nerve responsible for moving the tongue. It innervates most of the intrinsic and extrinsic muscles of the tongue.
