Question

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

• A. Epiglottis
• B. Glottis
• C. Larynx
• D. Pharynx

Answer 1

The correct option is A Epiglottis

• 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'.
