Answer:
Here options b,c,d, e are correct and only option a is incorrect.
Explanation:
Option a is wrong because smooth muscle fibers are those fibers which are commonly found in a persons stomach or even in the intestines , so therefore we can definitely say that tongue is not made up of smooth muscle fibers.
Option b is right , tongue is made up of striated muscle fiber and not only this tongue actually consists of eight types of muscles which includes both intrinsic and extrinsic types of muscles.
Lingual mucosa is nothing but a gland which forms the surface of the tongue, that helps in getting sensory reception for the taste , as this mucosa consists of nerve endings that help a person in taste perception.
Option d is also correct as this hypoglossal nerve provides a somatic motor function to the tongue by innervating almost all of the muscles of tongues except the palatoglossus muscle.
the last option is also correct as tongue plays a very important part in the digestive and respiratory functions of the body. Tongue helps in digestion of the food because tongue helps us in tasting the food and properly mixing the food with the saliva, that will create bolus , that is further pushed in to oesophagus.
