Answer 2

Larynx is the cartilaginous box which help in sound production. Larynx is also known as sound box.

In Larynx there are two pairs of vocal cords for sound production.

$\bigstar$ Anterior pair (false vocal cords) :

• They are pink in colour. These composes of mucus membranes.
• They provide moisture to true vocal cords.

$\bigstar$ Posterior pair (True vocal cords) :

• These composes of sheet of yellow fibrous connective tissue.
• They produce sound.
• In males the vocal cords are long and thicker and produce low pitch voice. whereas in women the vocal cords are short and produce high pitch voice.

Larynx is supported by 3 unpaired and 3 paired cartilages.

• Thyroid cartilage : They are single, dorsally incomplete and hyaline cartilage.
• Epiglottis : They are single, flat and elastic cartilage.
• Cricoid cartilage : They are single, ring shaped and hyaline cartilage.
• Cartilage of Santorini : One pair, node like cartilage.
• Arytenoid cartilage : They are one pair, pyramid shaped hyaline cartilage.
• Cuneiform cartilage : They are one pair cartilage.
