|
three things about the jugulodigastric node
|

A patient is being examined for laryngeal dysfunction. Upon examination you note that all intrinsic muscles of the larynx are affected with ONE exception. The exception, and reason for this, is:
|
the cricothyroid, as it is the only laryngeal muscle innervated by the superior laryngeal nerve.
|
|
|
the internal branch of the ______ nerve carries SVA fibers to the epiglottis
|
superior laryngeal

|
the remnants of the thyroglossal duct, with some glandular tissue attached
