===Dorsal cricoarytenoid muscle===

+

*Innervated by the caudal laryngeal nerve a branch of the vagus nerve ([[Nervous System - CNS - Anatomy & Physiology#Innervation - Cranial Nerves|CN X]])

*Dorsal surface of cricoid cartilage to arytenoid cartilage

*Abducts vocal process and therefore vocal fold

Line 163: Line 164:

===Lateral cricoarytenoid muscle===

+

*Innervated by the caudal laryngeal nerve a branch of the vagus nerve ([[Nervous System - CNS - Anatomy & Physiology#Innervation - Cranial Nerves|CN X]])

*Adducts vocal processes

*Narrows the glottis

===Thyroarytenoid muscle===

+

*Innervated by the caudal laryngeal nerve a branch of the vagus nerve ([[Nervous System - CNS - Anatomy & Physiology#Innervation - Cranial Nerves|CN X]])

*Laryngeal floor to the thyroid cartilage and arytenoid cartilage

*Alters the tension of the vocal and vestibular folds

Line 172: Line 175:

===Transverse arytenoid muscle===

+

*Innervated by the caudal laryngeal nerve a branch of the vagus nerve ([[Nervous System - CNS - Anatomy & Physiology#Innervation - Cranial Nerves|CN X]])

*Completes the muscular sphincter arrangment

*Spans the arytenoid cartilages
