What elevates and retracts the larynx?

The suprahyoid muscles are four muscles located above the hyoid bone in the neck. They are the digastric, stylohyoid, geniohyoid, and mylohyoid muscles.

What elevates and retracts larynx as its sole function?

stylohyoid. – sole function is to elevate and retract larynx. – arises from the styloid process of temporal bone and inserts into the hyoid.

Which membrane fills the space between the cricoid cartilage and the trachea?

The cricothyroid membrane (or conus elasticus) extends from the upper margin of the cricoid cartilage and attaches to the back of the thyroid cartilage anteriorly and the arytenoid cartilage posteriorly. Its upper free margin is the vocal ligament (true vocal fold).

Which cartilage articulates with the inferior aspect of the Arytenoid cartilage?

corniculate cartilages
The corniculate cartilages are 2 small, conical cartilages that articulate with the apices of the arytenoid cartilages, serving to extend them posteriorly and medially. They are located in the posterior parts of the aryepiglottic folds of mucous membrane.

What is the main function of the larynx?

The most basic function of the larynx is to provide sphincteric protection of the lower airway, most efficiently achieved by simultaneous adduction of both vocal cords. Such action serves to close the glottis by involving the activation of both thyroarytenoid muscles, among other groups of adductors.

What are three functions of the larynx?

The larynx serves three important functions in humans. In order of functional priority, they are protective, respiratory, and phonatory. A sound understanding of these functional priorities appears essential to the management of the myriad diseases besetting this complex organ.

What do you call the tube that delivers air from the mouth and nose to the trachea?

Pharynx (throat): Tube that delivers air from your mouth and nose to the trachea (windpipe).

Which is the most prominent cartilage found in larynx?

thyroid cartilage
The thyroid cartilage is a large, prominent structure which is easily visible in adult males. It is composed of two sheets (laminae), which join anteriorly to form the laryngeal prominence (Adam’s apple).

What is the function of arytenoid cartilage?

The arytenoid cartilages help move the vocal folds allowing tension, relaxation, or approximation of these because the vocal folds, being attached to the arytenoids, move along with them. Several intrinsic laryngeal muscles and ligaments are also attached to the arytenoids and can move them around.
