]]>The Pharynx is a funnel shaped tube which is about 12 to 13 cm long. It extends from the posterior nares to the level of cricoid cartilage. The pharynx lies superior to the larynx (voice box) , posterior to the nasal and oral cavities and lastly anterior to the cervical vertebra. the wall of pharynx is made of skeletal muscle and lined by mucous membrane and because of the contraction in skeletal muscle, pharynx assists in deglutition i.e swallowing.
Further pharynx is divided in 3 portions to understand its anatomy more wisely. the 3 portions are
1. Nasopharynx
2. Oropharynx
3. Laryngopharynx.
Now we will study about these parts separately

C. 5cm D. 18cm
2. Which structure is associated superiorly to the pharynx?
A. Cervical vertebra B. Inferior surface of skull
C. Larynx D. esophagus
3. What all are the part of pharynx?
A. Nasopharynx B. Laryngopharynx
C. Oropharynx D. All of the above
4. The pharynx functions as a protective region because of?
A. tonsils B. Sinuses
C. internal nares D. Opening to auditory tube
5. The portion of pharynx which extends to the hyoid bone is?
A. Nasopharynx B. tonsils
C. Laryngopharynx D. Oropharynx
6. Which of the following statement is NOT true?
A. The pharynx lies superior to larynx
B. the pharynx is funnel shaped tube
C. The nasopharynx is lined by mucous membrane
D. Sympathetic supply to the pharynx is done by vagus nerve
7. Which of the following is found in laryngopharynx?
A. Adenoids B. Palatine tonsil
C. Lingual tonsil D. None of the above
8. Match the following-
