Deck 24: The Tongue

Question 1

The circumvallate papillae anatomically divide the anterior two-thirds of the palate from the posterior one-third because they are positioned about two-thirds of the way back on the tongue.

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.

Answer 1

D
The circumvallate papillae,also called the vallate papillae,divide the anterior two-thirds of the tongue from the posterior one-third.The group of 13 elevated and circular papillae are arranged in the shape of a V with the point of the V facing posteriorly.

Question 2

Contraction of the longitudinal muscles lengthens the tongue because this muscle group is longest in length.

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.

Answer 2

E
Contraction of the longitudinal muscles shortens the tongue.This occurs because the longitudinal muscles,both superior and inferior,run anterior to posterior within the tongue.Note that shortening the tongue makes it wider and thicker.

Question 3

Foliate papillae are located on which portion of the tongue?

In humans,the foliate papillae are not as well developed nor do they contain as many taste buds as in lower forms of animals.

Question 7

Each of the following is involved in the formation of the tongue EXCEPT one.Which one is the EXCEPTION?

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

Question 9

The genioglossus muscle is considered extrinsic because it starts and ends wholly in the tongue.

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.

The tongue develops from a swelling that arises out of the anterior portion of the pharyngeal arches.This swelling develops from the future floor of the mouth.

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

Question 12

The tongue is an epithelial sac filled with muscle,connective tissue,and fat.Muscle component is categorized as voluntary striated muscle.

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

Question 13

The root of the tongue and the epiglottis develop from the copula.The arch of origin is the fourth pharyngeal.

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

Question 14

Contraction of the vertical group of fibers causes the tongue to become longer and wider because this muscle group runs from side to side.

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 15

The circumvallate papillae are also referred to filiform.The fungiform and vallate papillae are located on the ventral surface of the tongue.

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

Question 16

Which of the following is a muscle that originates from an outside structure but inserts into the tongue?

A) Hyoglossus
B) Genial tubercles
C) Vertical group
D) Circumvallate

Question 17

Redness and enlarged tissue near the midline and just behind the vallate papillae may indicate infection because this is the location of the lingual tonsil.

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 18

The ventral surface of the tongue is keratinized.The dorsum of the tongue has thick parakeratinized to keratinized epithelium.

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

Question 19

Which muscle group runs anterior to posterior and lies near the ventral surface of the tongue?

A) Superior longitudinal group
B) Inferior longitudinal group
C) Transverse group
D) Vertical group

Question 20

When the transverse fiber group overextends,a condition called hairy tongue can result because food and bacterial pigments become trapped between the papillae.

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.
