"Fluctuations of hormone grehlin levels results in sensation of hunger and motivation of consuming food.
When you feel your stomach is full and there is no need of food any more. Another hormone leptin that gets secreted suppresses hunger.
When we take food into the mouth it has to be chewed thoroughly. For this purpose the circular muscles help in chewing actions, while the surface muscles of the jaw moves the jaw up, down, forward and backward during food mastication.
The second cranial nerve controls the muscles of the jaw. Under the action of autonomous nervous system Saliva is released by the salivary glands moistens the food to make chewing and swallowing easier.
The salivary lipase in the saliva breaks down the starch into sugars.
As a result of chewing the food is transported into the oesophagus by the action of swallowing which is coordinated by the swallowing centre in the diencephalon and the mid brain.
The tongue which is gustatory recognizes the taste and optic nerve plays an important role in sensation of taste.
