Answer 2

reduces diameter of pharynx (peristaltic movements for swallowing)

Question 3

(Muscles of the Pharynx)

(Inferior pharyngeal constrictor): Thyropharyngeus muscle

Answer 3

reduces diameter of lower pharynx (peristaltic movements for swallowing)

Question 4

Answer 4

constricts opening of the esophagus

Question 5

(Muscles of the Pharynx): Salpingopharyngeus
