Larynx

This tutorial explores the anatomy and functions of the larynx, also known as the voice box. It covers the cartilages, ligaments, membranes, and muscles involved in sound production and airway protection. The video also discusses clinical aspects, such as muscle tension dysphonia, and concludes with a summary of key points.

What is the primary function of the larynx?

• To digest food

• To filter toxins

• To produce sound and protect airways

• To circulate blood

Which cartilage is known for forming the Adam's Apple?

• Thyroid cartilage

• Arytenoid cartilage

• Epiglottis

• Cricoid cartilage

Which of the following is NOT a paired cartilage of the larynx?

• Epiglottis

• Cuneiform cartilage

• Corniculate cartilage

• Arytenoid cartilage

What is the role of the thyrohyoid membrane?

• Connects the vocal folds to the thyroid cartilage

• Connects the arytenoid cartilage to the epiglottis

• Connects the cricoid cartilage to the trachea

• Connects the thyroid cartilage to the hyoid bone

Which ligament is known as the false vocal cord?

• Vocal ligament

• Thyrohyoid ligament

• Cricothyroid ligament

• Vestibular fold

Which muscle is responsible for lengthening the vocal folds to produce a higher pitch?

• Thyroarytenoid muscle

• Cricothyroid muscle

• Posterior cricoarytenoid muscle

• Lateral cricoarytenoid muscle

What is the function of the posterior cricoarytenoid muscle?

• Abducts the vocal folds

• Relaxes the vocal folds

• Tenses the vocal folds

• Adducts the vocal folds

Which nerve innervates most of the intrinsic muscles of the larynx?

• Glossopharyngeal nerve

• Hypoglossal nerve

• Inferior laryngeal nerve

• Superior laryngeal nerve

What is a common symptom of muscle tension dysphonia?

• Enhanced sound production

• Voice fatigue and discomfort

• Increased vocal range

• Improved vocal quality

What is the primary treatment for muscle tension dysphonia?

• Medication

• Radiation therapy

• Voice therapy

• Surgery
