The main biological function of the larynx is to protect this structure from foreign material.
What is the airway?
This spoon-shaped elastic cartilage forms the lid of the larynx.
What is the epiglottis?
This fibroelastic sheet connects the hyoid bone and thyroid cartilage and allows passage for the internal superior laryngeal nerve.
What is the thyrohyoid membrane?
This is the variable opening between the true vocal folds.
What is the rima glottidis (or glottis)?
The vocal folds contain this many layers of tissue.
What are five layers?
The larynx sits between these two major structures of the respiratory tract.
What are the pharynx and the trachea?
This U-shaped bone suspends the larynx and does not articulate with any other bone.
What is the hyoid bone?
This ligament connects the hyoid bone to the epiglottis and allows its movement during swallowing.
What is the hyoepiglottic ligament?
This entryway to the larynx is surrounded laterally by the aryepiglottic folds.
What is the vestibule?
This portion of the lamina propria contains elastin fibers arranged randomly and gives the folds their stretchiness.
What is the superficial layer?
During phonation, the vocal folds move to this position to allow vibration.
What is midline approximation (or adduction)?
This ring shaped structure sits below the thyroid cartilage and above the trachea.
What is the cricoid cartilage?
This membrane connects the cricoid cartilage to the first tracheal ring.
What is the cricotracheal membrane (or ligament)?
This is another name for the false vocal cords.
What are the ventricular (or vestibular) folds?
This outermost layer of the vocal fold is composed of squamous epithelium.
What is the epithelium (with basement membrane)?
This cartilage forms the “Adam’s apple” and the anterior wall of the larynx.
What is the thyroid cartilage?
These paired pyramid-shaped cartilages sit atop the cricoid and anchor the vocal folds.
What are the arytenoid cartilages?
This intrinsic membrane connects the cricoid, thyroid, and arytenoid cartilages and gives rise to the vocal ligaments.
What is the conus elasticus?
This space lies between the aryepiglottic folds and the pharyngeal wall and can collect residue during swallowing.
What are the pyriform sinuses?
This muscle forms the body of the vocal fold and provides active tension control.
What is the thyroarytenoid muscle?
The larynx closes to help generate this kind of pressure needed for lifting, coughing, or defecation.
What is intrathoracic pressure?
These are parts of the thyroid cartilage?
What are the
• Thyroid laminae
• Thyroid notch
• Laryngeal prominence
• Angle
• Oblique line
• Superior cornua
• Inferior cornua
This membrane connects the lateral margins of the epiglottis to the arytenoids and contributes to the aryepiglottic folds.
What is the quadrangular membrane?
This vestibule is surrounded by these folds.
What is laterally by the aryepiglottic folds?
The lamina propria contains these three layers of connective tissue.
What are the superficial LP, intermediate LP, & Deep LP?
