Variability Of Cranial Nerve Assignment To Speech And Swallow Muscles, Kristina Morrey

Undergraduate Honors Capstone Projects

The object of this study was to examine and document anatomical variability of cranial nerve assignment for muscles of the speech and swallow mechanism. Through means of textbook review, the study’s first purpose was to identify which cranial nerves were attributed to the innervation for muscles associated with the speech and swallow mechanism. The second purpose was to examine if cranial nerve assignment, field of study, or geographic region explained differences in cranial nerve assignment to muscles of the head and neck.
