Classification

Terminologia Anatomica currently breaks the artery into four parts: "cervical", "petrous", "cavernous", and "cerebral".

The Laryngeal nerve, or Galen's nerve, is a nerve originating from the vagus nerve. It is comprised of two branches, the cranial, which leaves the vagus at the distal ganglion and passes ventrally to the larynx supplying the cricothyroid muscle and laryngeal mucosa, and the
