]]>The larynx performs several functions which are as follows
2. SPEECH- speech is produced when the sound is produced by the cords which is further amplified by lips tongue and mouth.
3. PROTECTION- from larynx the lower respiratory tract starts hence it protects the same. It prevents backflow of food back to pharynx by moving upwards. Also the epiglottis closes during swallowing which ensures that the food enters the esophagus and not the trachea.
4. Larynx helps in passageway of air from pharynx to trachea and also humidifies , filters and warms the air that passes by.

]]>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
There are 5 major functions of pharynx which are as follows:-
1.How long is the pharynx?
A. 12cm B. 20cm
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-
(a)superior portion of pharynx 1. Mucous membrane
(B)inferior portion of pharynx 2.nonkeratinized squamous epithelium
(C ) oropharynx is lined by
(d) nasopharynx is lined by 3.laryngopharynx
4. nasopharynx
9. The nasopharynx extend till?
A. Soft palate B. Internal nares
C. HYOID BONE D. Cricoid cartilage
10. The sympathetic supply to pharynx is done through which nerve?
A. Vagus nerve B. Glossopharyngeal nerve
C. Facial nerve D. Nerve from the superior cervical ganglia
ANSWERS:-
1. 12cm
2. inferior surface of skull
3. all of the above
4. tonsils
5. oropharynx
6. sympathetic supply is done by vagus nerve
7. none of the above
8. (A) – 4 (B) – 3 (C) – 2 (D) – 1
9. Soft palate
10. nerve from the superior cervical ganglia
