**Cranial larygeal nerve

 

***Internal branch innervates mucosa

===Cranial larygeal nerve===

***External branch innervates cricothyroid muscle and constrictors of [[Pharynx - Anatomy & Physiology|pharynx]]

The internal branch innervates the mucosa and the external branch innervates the '''cricothyroid muscle''' and constrictors of the [[Pharynx - Anatomy & Physiology|pharynx]].

**Caudal (recurrent) laryngeal nerve

 

***Innervates intrinsic muscles of larynx (except cricothyroid muscle)
