Antagonist to Cricothyroid? | Lateral cricothyroid |
What muscle of the larynx is an antagonist to the cricothyroid muscle? | Thyroarytenoid |
What laryngeal muscles aBduct the vocal cords? | Posterior cricoarytenoid |
What muscle of the larynx extends from posterior surface of the cricoid lamina to the muscular process of the arytenoids cartilage? | Posterior cricoarytenoid |
What muscle of the larynx inserts on the muscular process of the arytenoid and rotates the cartilage medially, but does not pull the cartilage anteriorly? | Lateral cricoarytenoid |
What muscle(s) of the larynx is/are not innervated by the recurrent laryngeal n.? | Cricothyroid |
What muscle of the larynx lengthens and tightens the vocal cord, thus increasing pitch? | Cricothyroid |
What muscle(s) of the larynx act(s) as a sphincter of the laryngeal inlet? | Oblique arytenoid and aryepiglottic muscles |
Besides the thyroid and cricoid cartilages, name the other cartilages of the larynx. | arytenoid, epiglottic, corniculate, cuneiform |

Describe the motor innervation (include components innervated) to the larynx. | recurrent laryngeal to all muscles except external branch of superior laryngeal n. to cricothyroid m. |
Entrance to larynx? | Aditus |
Located immediately medial to the thyroarytenoid, it acts to tense the vocal cords? | Vocalis |
Give the term for the space between the true and false vocal cords. | Ventricle |

Slit-like opening between the true vocal cords. | Rima glottidis |
Name given to mucosal reflection formed by the lower edge of the quadrangular membrane. | Vocal ford |

Place in which the sphenoid sinus drains? | Sphenoethmoidal recess |
Hypertrophied lymphatic components on the roof of the nasopharynx. | Adenoids |
Give 2 components of lateral wall of the nasopharynx? | Ostia of auditory tubes & pharnygeal muscles |
Structure over which the mucosa of the larynx is reflected to form the vestibular fold. | Quadrangular membrane |
Define the root of the lung. | The structures which pass through the hilus = bronchi, vessels, nerves, and lymphatics |
