A. Mucosa
B. Papillae
C. Taste buds
D. All of the above

Answer 1

Hint: Human tongue is covered by tunica mucosa linguae. Along with this membrane and tiny bumps, the tongue appears to be velvety.

Complete answer: The tongue is a muscular organ located inside our mouth. In humans, it is divided into two parts: an oral part (at the front) and a pharyngeal part (at back). The muscles of the tongue are interwoven and striated type.
The left and right portions of the tongue are separated an incomplete vertical section of fibrous tissue- lingual septum.
It results in a groove on the surface and it is called the median sulcus.
The human tongue is covered with moist, pink mucosa tissue.
It is basically the mucous membrane or tunica mucosa linguae present at the surface of the tongue. It appears velvety due to the presence of tiny bumps called papillae.
There are also several taste buds on the tongue.

Additional information: According to Guinness World Records, which will include Stoeberl in the 2015 edition of its famous book, says that the average tongue is 10cm long when measured from the oropharynx - the region in the back of the throat where the tongue starts - to the tip.

So, the correct answer is A. Mucosa.

Note: Tongue papillae can be of four types: foliate, filiform, fungiform and circumvallate papilla. The taste buds are distributed all over the tongue but different portions of the tongue contain different types of taste buds. E.g. the tip of the tongue is responsible for sweet taste.
