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.

Muscles that elevate the posterior part of the tongue and pull it slightly backward are categorized as

The tongue begins to develop in the embryo,shortly after the buccopharyngeal membrane ruptures.This event occurs at about weeks.

The genioglossus pair of muscles aids in each of the tongue actions EXCEPT one.Which one is the EXCEPTION?

The anterior two-thirds of the tongue is covered with ectoderm-derived epithelium.This portion of the tongue originates from the copula of the third arch.

The area near the midline on the dorsum of the tongue,behind the vallate papillae,is known as the

Which of the following have taste buds (Select all that apply. )?

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

Muscles that have their origin and insertion within the tongue are extrinsic muscles.

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.

The tongue muscles that run from side to side are from which group of muscles?

The lingual tonsils help to fight infection.

The tongue is similar to the gingiva in indicating a patient's overall health.

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

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

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.

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

The area MOST likely to develop undetected oral cancer is the

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