Deck 31: Soft Palate and Pharynx

Question 1

During speech the soft palate moves both forward and backward. The backward movement is accomplished by the levator veli palatini.

A) Both statements are true.
B) The first statement is true; the second is false.
C) The first statement is false; the second is true.
D) Both statements are false.

Answer 1

C
During speech the soft palate moves up and back to contact the posterior pharyngeal wall. This is accomplished primarily by the levator veli palatine as well as the muscles of the uvula.

Question 2

The structure that helps to open the auditory tube, if it is edematous and closed, is the

A) Palatoglossal muscle
B) Palatopharyngeal muscle
C) Levator veli palatine
D) Stylopharyngeal muscle

Answer 2

C
If the auditory tube is edematous and closed, the lavatory veli palatini pulls the posterior end of the soft palate up and back to contact the posterior pharyngeal (throat) wall.

Question 3

The stylopharyngeal muscle is the primary dilator of the pharynx. This muscle originates in the end of the auditory tube in the lateral wall of the nasal pharynx.

A) Both statements are true.
B) The first statement is true; the second is false.
C) The first statement is false; the second is true.
D) Both statements are false.

Answer 3

B
The stylopharyngeal muscle originates from the medial side of the base of the styloid process. It is the salpingopharyngeal muscle that originates from the end of the auditory tube in the lateral wall of the nasal pharynx.

Question 8

The posterior faucial pillar is formed by the palatopharyngeal muscle. When constricted, it depresses the pharynx and elevates the larynx.

A) Both statements are true.
B) The first statement is true; the second is false.
C) The first statement is false; the second is true.
D) Both statements are false.

C) The statement is correct, but the reason is NOT correct.
D) The statement is NOT correct, but the reason is correct.
E) NEITHER the statement NOR the reason is correct.

Question 12

The pharynx has four components. The laryngeal pharynx is a middle component of the pharynx.

A) Both statements are true.
B) The first statement is true; the second is false.
C) The first statement is false; the second is true.
D) Both statements are false.

Question 13

The palatoglossal muscle originates about halfway back the length of the palate because its point of origin is at the posterior end of the hard palate and the anterior end of the soft palate.

A) Both the statement and the reason are correct and related.
B) Both the statement and the reason are correct but are NOT related.
C) The statement is correct, but the reason is NOT correct.
D) The statement is NOT correct, but the reason is correct.
E) NEITHER the statement NOR the reason is correct.

Question 14

Pharyngeal elevator muscles elevate and dilate the pharynx. These actions are necessary to prevent food from entering the esophagus.

A) Both statements are true.
B) The first statement is true; the second is false.
C) The first statement is false; the second is true.
D) Both statements are false.

C) The statement is correct, but the reason is NOT correct.
D) The statement is NOT correct, but the reason is correct.
E) NEITHER the statement NOR the reason is correct.

Question 17

The levator veli palatini helps open the auditory tube because this muscle pulls the soft palate laterally.

A) Both the statement and the reason are correct and related.

C) The statement is correct, but the reason is NOT correct.
D) The statement is NOT correct, but the reason is correct.
E) NEITHER the statement NOR the reason is correct.
