Rima glottidis: The rima glottidis is the opening between the true vocal cords and the arytenoid cartilages.Posterior cricoarytenoid muscle: The posterior cricoarytenoid muscles are extremely small, paired muscles that extend from the posterior cricoid cartilage to the arytenoid cartilages in the larynx.Cricoid cartilage: The cricoid cartilage , or simply cricoid (from the Greek krikoeides meaning "ring-shaped"), is the only complete ring of cartilage around the trachea. It forms the back part of the voice box and functions as an attachment site for muscles, cartilages, and ligaments involved in opening and closing the airway and in producing speech.Infraglottic cavity: The infraglottic cavity is the portion of the larynx below the laryngeal ventricles and the rima glottidis.Vocal cord paresisArticular cartilage repair: The aim of an articular cartilage repair treatment is to restore the surface of an articular joint's hyaline cartilage. Over the last decades, surgeons and researchers have been working hard to elaborate surgical cartilage repair interventions.Pharyngeal consonant: A pharyngeal consonant is a consonant that is articulated primarily in the pharynx. Some phoneticians distinguish upper pharyngeal consonants, or "high" pharyngeals, pronounced by retracting the root of the tongue in the mid to upper pharynx, from (ary)epiglottal consonants, or "low" pharyngeals, which are articulated with the aryepiglottic folds against the epiglottis in the lower larynx, and even epiglotto-pharyngeal consonants consisting of both those movements combined.Janwillem van den Berg: Janwillem van den Berg (20 November 1920 in Akkrum – 18 October 1985 in Akkrum) was a Dutch speech scientist and medical physicist who played a major role in establishing the myoelastic-aerodynamic theoryTitze, I. R.Mallampati scorePiriform sinus: On either side of the laryngeal orifice is a recess, termed the piriform sinus (also piriform recess, pyriform sinus, piriform fossa, or smuggler's fossa), which is bounded medially by the aryepiglottic fold, laterally by the thyroid cartilage and thyrohyoid membrane. The fossae are involved in speech.List of voice disorders: Voice disordersTitze, I.R.
