Muscles of larynx

The larynx (Latin larynx ) is surrounded by various skeletal muscles and moves, as the laryngeal muscles (musculi laryngeal ) are referred to. They have a different influence on the glottis and vocal cords.

The muscles are usually named after the two cartilages, between which they run:

• Thyroid cartilage (Latin thyroid cartilage )
• Cricoid cartilage (Latin cricoid cartilage )
• Arytenoid cartilage (Latin cartilage arytenoid )
• Epiglottis cartilage ( cartilage Latin epiglottica ).

Laryngeal muscles of the human

Special features of the other mammals

In non - primates, the laryngeal muscles behave except for a few differences as well. The following features should be noted:

• The musculus musculus cricoarytaenoideus cricoarytaenoideus posterior dorsalis is called. He is also in the animals the only Stimmritzenerweiterer, while all other muscles constrict the glottis.
• The Musculus thyreoarytaenoideus is in horses and dogs in two muscular legs, namely the front and the rear musculus musculus vocalis ventricularis divided. Between these two muscles on the side pocket larynx ( laryngeal ventricle ) juts from the larynx interior from the side.
• Horses also have a muscle thyreoarytaenoideus accessory and a tensor laryngeal ulcer.
• The Musculus hyoepiglotticus ( between hyoid bone and epiglottis ) is also counted among the laryngeal muscles.
• Arytenoid muscle oblique muscle, musculus musculus and aryepiglotticus thyreoepiglotticus missing most non - primates.
