The larynx (/ ˈ l æ r ɪ ŋ k s /), commonly called the voice box, is an organ in the top of the neck involved in breathing, producing sound and protecting the trachea against food aspiration. The opening of larynx into pharynx known as the laryngeal inlet is about 4–5 centimeters in diameter. [1]
The vocal folds are located within the larynx at the top of the trachea. They are attached at the back to the arytenoid cartilages, and at the front to the thyroid cartilage via Broyles ligament. They are part of the glottis. Their outer edges are attached to muscle in the larynx while their inner edges form an opening called the rima glottidis.
The vocal tract is the cavity in human bodies and in animals where the sound produced at the sound source (larynx in mammals; syrinx in birds) is filtered.. In birds, it consists of the trachea, the syrinx, the oral cavity, the upper part of the esophagus, and the beak.
The cricoid arch is the curved and vertically narrow anterior portion of the cricoid cartilage. Anteriorly, it measures 5-7 mm superoinferiorly; it becomes wider on eithers side towards its transition into the cricoid lamina of that side.

The anterior or lingual surface of the epiglottis is curved forward, and covered on its upper, free part by mucous membrane which is reflected on to the sides and root of the tongue, forming a median and two lateral glossoepiglottic folds; the lateral folds are partly attached to the wall of the pharynx.
