  1. Pharynx

  2. Larynx

  3. Glottis

  4. Bronchial tube

Show answer
Correct Option: B
Explanation:
  • The larynx (voice box) is a cartilaginous box which helps in sound production.
  • It consists of 9 cartilages among them 3 are paired and 3 are unpaired.
  • Vocal cords are composed of twin infoldings of mucous membrane stretched horizontally across the larynx. They vibrate, modulating the flow of air being expelled from the lungs during phonation.
  • Hence vocal cords occur in Larynx.
  • So, the correct answer is 'Larynx'.

  2. Nose

  3. Hyoid

  4. Sternum

Show answer
Correct Option: A
Explanation:

The arytenoid cartilages are a pair of small cartilages, shaped roughly like three-sided pyramids, which are located toward the rear of the larynx and play a vital role in positioning and adjusting the vocal folds during speech.

So, the correct option is is 'Larynx'.

_____ projects obliquely upwards behind the tongue and the hyoid bone, pointing dorsally.

biology breathing and respiration regulation of breathing human respiratory system contro and disorders of respiration

  1. Epiglottis

  2. Glottis

  3. Larynx

  4. Pharynx

Show answer
Correct Option: A
Explanation:
    • The epiglottis is a large, leaf-shaped piece of cartilage lying on top of the larynx. It projects obliquely upwards behind the tongue and the hyoid bone, pointing dorsally.
    • During swallowing of food the larynx elevates, causing the epiglottis to fall on the glottis (opening into larynx) like a lid, closing it off, this prevents food from entering the windpipe (trachea). Hence The structure which prevents the entry of food particles into the respiratory passage is Epiglottis.
    • So, the correct answer is 'Epiglottis'.
