cricoid cartilages การใช้

• This figure demonstrates control of the position of the cricoid cartilage.
• The thyroid cartilage and cricoid cartilage lie just above the gland, below the Adam's apple.
• The cricoid cartilage is attached to the top of the trachea and acts as the bottom of the larynx.
• The posterior edge of each half articulates with the cricoid cartilage inferiorly at a joint called the cricothyroid joint.
• Examples include the rings of the trachea, such as the cricoid cartilage and auricle / pinna of the ear.
• A medical procedure known as a cricoidectomy can be performed in which part or all of the cricoid cartilage is removed.
• Belting or belt quality is a complex setup combining speech quality, twang quality, a tilted cricoid cartilage and raised larynx.
• The Sellick Maneuver is performed by applying gentle pressure to the anterior neck ( in a posterior direction ) at the level of the Cricoid Cartilage.
• The trachea is surrounded by rings of hyaline cartilage; these rings are incomplete and C-shaped, except for the first ring, called the cricoid cartilage.
• The "'Cricoarytenoid ligament "'extends from the lamina of the cricoid cartilage to the medial surface of the base and muscular process of the arytenoid cartilage.
• Killian's diverticulum is formed in the Killian-Jamiseon triangle ( located inferior to the cricopharyngeus on both sides of this muscle's insertion into the cricoid cartilage ).
• Areas near the cricoid cartilage and carina are fixed to the thyroid cartilage and the pericardium respectively; thus if the airways move, they can tear at these points of fixation.
• The picture ( Respiratory system complete en . svg ) has three errors in the labelling : " Cricoid cartilage ", " Lingular division bronchus " and " Intermediate bronchus ".
• In roughly 1 out of every 100 & ndash; 200 people, the right inferior laryngeal nerve is nonrecurrent, branching off the vagus nerve around the level of the cricoid cartilage.
• The arytenoids articulate with the supero-lateral parts of the cricoid cartilage lamina, forming the cricoarytenoid joints at which they can move apart, tilt anteriorly or posteriorly, and rotate.
• Their " efferents " pass partly to the submandibular lymph nodes and partly to a gland of the deep cervical group situated on the internal jugular vein at the level of the cricoid cartilage.
• In Estill Voice training it is proposed that specific positioning of the cricoid cartilage is a typical part of the vocal set-up for shouting and other high-intensity voice productions employing higher subglottic pressure.
• Uncuffed tubes are also available, though their use is limited mostly to children ( in small children, the cricoid cartilage is the narrowest portion of the airway and usually provides an adequate seal for mechanical ventilation ).
• Another key feature of RSI is the application of manual'cricoid pressure'to the cricoid cartilage, often referred to as the " Sellick maneuver ", prior to instrumentation of the airway and intubation of the trachea.
• Uncuffed tubes are also available, though their use is limited mostly to pediatric patients ( in small children, the cricoid cartilage, the narrowest portion of the pediatric airway, often provides an adequate seal for mechanical ventilation ).
