Q1. What are the two anatomical parts of the rima glottidis?
- Supraglottic and infraglottic parts
- Anterior and posterior vestibular parts
- Thyroid and cricoid parts
- Intermembranous and intercartilaginous parts
Q2. Which portion forms the larger anterior part of the rima glottidis?
- Intermembranous part
- Laryngeal ventricle
- Intercartilaginous part
- Vestibule
Q3. Which portion of the rima glottidis lies between the arytenoid cartilages posteriorly?
- Intermembranous part
- Supraglottic part
- Intercartilaginous part
- Subglottic recess
Q4. Which muscle adducts the vocal folds by medially rotating the arytenoid cartilages?
- Lateral cricoarytenoid
- Thyrohyoid
- Cricothyroid
- Posterior cricoarytenoid
Q5. Which muscles are especially important for closing the posterior intercartilaginous part of the rima glottidis?
- Transverse and oblique arytenoids
- Sternothyroids
- Cricothyroids
- Posterior cricoarytenoids
Q6. Which muscle primarily tenses and lengthens the vocal folds?
- Cricothyroid
- Posterior cricoarytenoid
- Thyroarytenoid
- Transverse arytenoid
Q7. Which nerve supplies the cricothyroid muscle?
- Internal branch of the superior laryngeal nerve
- External branch of the superior laryngeal nerve
- Glossopharyngeal nerve
- Recurrent laryngeal nerve
Q8. Which muscle can relax the vocal ligament by drawing the arytenoid cartilage anteriorly?
- Cricothyroid
- Posterior cricoarytenoid
- Inferior pharyngeal constrictor
- Thyroarytenoid
Q9. What is the vocalis muscle?
- The medial part of the thyroarytenoid that finely adjusts vocal fold tension
- A pharyngeal muscle that closes the laryngeal inlet
- The lateral part of posterior cricoarytenoid
- A subdivision of cricothyroid that abducts the folds
Q10. How does the shape of the rima glottidis change during forced inspiration?
- Only the anterior part opens while the posterior part remains closed
- It closes completely to increase airway pressure
- It becomes widely open as the vocal folds are strongly abducted
- The vestibular folds replace the true vocal folds
