Definition
| Structure lies at the top of the trachea anterior portion of the neck. It is a valving mechanism that opens and closes as well as houses the vocal folds. |
|
|
Term
| Biological functions of the larynx include: |
|
Definition
| closure of the trachea so that food and other substances do not enter the lungs, production of the cough reflex to expel foreign substances that accidentally enter the trachea, and closure of the vocal folds to build subglottic pressure necessary for physical tasks. |

| Some view as the uppermost tracheal ring and is linked with the thyroid cartilage and the paired arytenoid cartilages. It completely surrounds the trachea. |
|
|
Term
|
Definition
| small, pyramid-shaped cartilages connected to the cricoid through the cricoarytenoid joint, which permits sliding and circular movements. |
|
|
Term
|
Definition
| sit on the apex of the arytenoids and assist in reducing the laryngeal opening when a person is swallowing. |
|
|
Term
|
Definition
| tiny cone-shaped cartilages which are located under the mucous membrane that covers the aryepiglottic folds. Serves to stiffen or tense the aryepiglottic folds. |
|
|
Term
| Intrinsic Laryngeal Muscles |
|
Definition
| Primarily responsible for controlling sound production. Muscles include: thyroarytenoid, lateral cricoarytenoid, transverse arytenoid, oblique arytenoid, cricothyroid, and posterior cricoarytenoid. |
|
|
Term
|
Definition
| is attached to the thyroid and arytenoid cartilages. |
|
|
Term
|
Definition
| generally referred to as the vocalis muscle or more commonly the vocal folds. |
|
|
Term
|
Definition
| lateral cricoarytenoid, transverse arytenoid, and oblique arytenoid. |
|
|
Term
|
Definition
| attached to the cricoid and thyroid cartilages. It lengthens and tenses the vocal folds. |
|
|
Term
|
Definition
| is supported when the oblique and transverse arytenoid muscles contract and pull the arytenoids closer together. |
|
|
Term
|
Definition
| accomplished when the posterior cricoarytenoid muscle contracts. |

Term
|
Definition
| adducts the vocal folds, increases medial compression. |
|
|
Term
|
Definition
| pulls the apex of arytenoids in a medial direction. |
|
|
Term
|
Definition
| It is not anatomical structure but a name of a space that is created when the vocal folds are abducted. |
|
|
Term
| Extrinsic Laryngeal Muscles |
|
Definition
| Attached to the hyoid bone and lower or raise the position of the larynx within the neck. |
|
|
Term
|
Definition
| Known as elevators that lie above the hyoid bone. Primary function is elevation of the larynx. |
|
|
Term
| Digastric, Geniohyoid, Mylohyoid, stylohyoid, hypglossus, and genioglossus. |
|
Definition
|
|
Term
|
Definition
| Known as depressors that lie below the hyoid bone. Primary function is depression of the larynx. |
|
|
Term
| Thyrohyoid, omohyoid, sternothyroid, and sternohyoid. |

|
Term
| Epithelium, lamina propria, vocalis muscle are... |
|
Definition
| three layers of the vocal folds. |
|
|
Term
|
Definition
| a ring of connective tissue and muscle extending from the tips of the arytenoids to the larynx. Separates the laryngeal vestibule from the pharynx and help preserve the airway. |
|
|
Term
| Ventricular, or false vocal folds |
|
Definition
| vibrate at very low fundamental frequencies and usually not during phonation in a normal speaker. Compress during such activities as coughing and lifting heavy items. |
|
|
Term
| Myoelastic-aerodynamic theory |
|
Definition
| vocal folds vibrate because of the forces and pressures of air and the elasticity of the vocal folds. |
|
|
Term
|
Definition
| caused by the increased speed of air passing between the vocal folds, is the "sucking" motion of the vocal folds toward one another. |
|
|
Term
| Primary cortical areas involved in speech-motor control |
|
Definition
| primary motor cortex, broca's area, somatosensory cortex, and supplementary motor cortex. |
