The lumen of the larynx can be divided into 3 parts, what are these?
Vestibule - area between laryngeal inlet and the vestibular folds (or false vocal cords)
Middle part - lies between vestibular folds and the true vocal cords
Lower part - extends from vocal cords to lower border of cricoid cartilage
Which one is the true vocal cords?
A
What do intrinsic muscles of the larynx control?
Movement of the vocal folds as well as controlling the diameter of the laryngeal inlet
What can the laryngeal intrinsic muscles do to the vocal cords?
Make them tighten, or relax,
and to be abducted or adducted (from the midline and each other)
What is A?
Epiglottis
