The muscles that help in chewing food in the mouth are

Read the following passag: As the process of digestion in the stomach nears completion, the contraction of the stomach decrease. This prompts the muscles called as pyloric shincter opening of the stomach and the first part of the small intestine or duodenum to realax. This opens the pathway into duodenum releasing the partially digested food (chyme) in small quantities into the duodenum. Peristalsis involves the contractin of the muscle behind the food and the relaxation of he muscles in front of the food and the relaxation of the muscles in front of the food giving rise to na thrust that pushes the food forward through the digestive canal. A wave of contraction followed by realaxtion in muscles help in forward movement of food. Wirte answer for the following questions. What is the use of peristalsis movement ?

Observe the following a, b statements. Teeth help in chewing and grindiing the food. Tongue mix the food with saliva and spread out the food evenly in the oral cavity.

Fill in the blanks with suitable words given below. Fluctuation s of hormone (i)_____________ 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 (ii)_____________ that gets secreted suppresses hunger. When we take food into the mouth it has to be chewed thoroughly. For this purpose the (iii)_____________ muscles help in chewing actions, while the (iv)_____________ muscles of the jaw moves the jaw up,down ,forward and backward during food mastication. The (v)_____________ nerve controls the muscles of the jaw. . Under the action of (vi)_____________ nervous system Saliva is released by the salivary glands moistens the food to make chewing and swallowing easier. The salivary (vii)_____________ 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 (viii)_____________ and the (ix)_____________. The tongue which is gustatory recognizes the taste and (x)_____________ nerve plays an important role in sensation of taste. Choose the right ones. 1) leptin, grehlin gastrin secretin. 2) ghrelin leptin secretin gastrin. 3) deep muscles ,surface muscles ,circular muscles, striated muscles. 4) surface muscles, deep muscles, neck muscles, long muscle. 5) fifth cranial nerve ,second cranial nerve,fifth facial nerve, spinal nerve. 6) central nervous system, peripheral nervous system autonomous nervous system. 7) lipase, sucrase, galactase,amylase. 8) medulla oblongata, cerebrum , 8th spinal nerve,cranial nerve.7th cranial nerve. 9) Pons varoli, brain stem ,medulla oblongata, mid brain. 10) 6^(th) cranial nerve, 5^(th) cranial nerve, 10^(th) cranial nerve, optic nerve.

Consider that you are passing by a garbage disposal area and you immediately cover your nose. Arrange the events belown in a logical order by marking them from (i) to (v) to trace the events that happen in the nervous system from detection of foul smell (stimulus generation) to covering your nose (response). (i) At the end of the axon, electrical impulse releases chemicals. (ii) Stimulus received by the dendritic cells of a neuron sets off chemical reaction that creates an electrical impulse. (iii) Electrical impulse transmitted through cell body and axon. (iv) The chemicals cross the synapse and reach the next neuron. Similarly, the electrical impulse crosses several neurons. (v) Finally, the impulse is delivered from neuron to the gland that helps in recognition of the foul smell and muscle cells that help in covering the nose.
