Name the four nucleuses which are connected to the vagus nerve.
Dorsal Vagal Nucleus - visceral efferent
Nucleus Ambiguus - branchial efferent

Superior Laryngeal Nerve
Name the nerve which is distributed to the posterior wall of the external acoustic meatus.
Auricular branch of vagus
Name the branch of the vagus which joins the posterior auricular nerve of the facial nerve
Auricular branch of vagus
Name the nerve which crosses the 1st part of the right subclavian artery
R side of the Recurrent Laryngeal N

Name the nerve which innervates the cricothyroid muscle
External Laryngeal n of Superior Laryngeal n
Name the nerve which winds the aortic arch just behind the ligamentum arteriosum
Left side of the Recurrent Laryngeal n
Name the nerve which innervates to all the laryngeal muscles except the cricothyroid muscle
Recurrent Laryngeal N of Vagus
Name the nerve which supplies sensory fibers to the mucous membrane below the vocal folds of the larynx.
