Q: Movement of alimentary canal does not help in slipping down of food is

\$\textbf{Correct answer: B}\$ \$\textbf{Option (A):}\$ \$\bullet\$ There are two types of movements in the alimentary canal observed for specific functions. \$\bullet\$ Peristaltic movement or peristalsis is responsible for moving down the food through the alimentary canal with the help of contraction and relaxation of the muscles present in the muscularis layer.\$\textbf{Option (B):}\$ \$\bullet\$ Segmentary or pendular movements are responsible for churning or the mixing of food with different digestive enzymes present in the alimentary canal. \$\bullet\$ This movement is just for facilitating the action of the digestive enzymes on the food. \$\bullet\$ This movement does not move the food in a downward direction like the peristaltic movement. Hence, the correct answer is option (B).

Q: A patient is generally advised to specially consume more meat, lentils, milk and eggs in diet only when he suffers from -

\$\textbf{Correct answer: C}\$ \$\textbf{Option (A):}\$ \$\bullet\$ If a person suffers from anaemia then they are advised to consume more food rich in iron. \$\bullet\$ This is because iron is required for the generation of haemoglobin. \$\textbf{Option (B):}\$ \$\bullet\$ Scurvy is caused due to deficiency of Vitamin C. The food material that is rich in vitamin C is prescribed to such patients. \$\textbf{Option (C):}\$ \$\bullet\$ Kwashiorkor occurs due to the deficiency of protein. \$\bullet\$ Such patients are prescribed a diet containing food materials like meat, lentils, milk and eggs which are rich in proteins. \$\textbf{Option (D):}\$ \$\bullet\$ The deficiency of Vitamin D3 and Calcium causes rickets. \$\bullet\$ Due to abnormal growth of the bones patients are prescribed to include food in their diet which is rich in calcium. Hence, the correct answer is option (C).

Question 1

Movement of alimentary canal does not help in slipping down of food is

Accepted Answer

$\textbf{Correct answer: B}$ $\textbf{Option (A):}$ $\bullet$ There are two types of movements in the alimentary canal observed for specific functions. $\bullet$ Peristaltic movement or peristalsis is responsible for moving down the food through the alimentary canal with the help of contraction and relaxation of the muscles present in the muscularis layer.$\textbf{Option (B):}$ $\bullet$ Segmentary or pendular movements are responsible for churning or the mixing of food with different digestive enzymes present in the alimentary canal. $\bullet$ This movement is just for facilitating the action of the digestive enzymes on the food. $\bullet$ This movement does not move the food in a downward direction like the peristaltic movement. Hence, the correct answer is option (B).

Question 2

Which of the following shows correct pairing for salivary glands in man?

Accepted Answer

The salivary juice from the glands to the oral cavity moves through the salivary duct. The parotid gland and the buccal mucosa is connected by the parotid duct (Stensen duct). The submandibular duct (Wharton duct) connects the submandibular gland to the floor of the mouth. The sublingual gland drains through numerous small ducts all of which open into the floor of the mouth and are collectively termed the duct of Rivinus. So, the correct answer is 'Parorid $\rightarrow$Duct of Stensen, submaxillary $\rightarrow$ Wharton's duct; sublingual $\rightarrow$ Duct of rivinus'.

Question 3

Meckel's diverticulum is found in_________.

Accepted Answer

Meckel's diverticulum is a bulge in the lower part (Ileum) of the small intestine. the bulge is congenital (present at birth) and is a leftover of the umbilical cord.Thus, Option A is correct.

Question 4

Which of the following is a proteolytic enzyme?

Accepted Answer

Proteolytic enzymes are that enzyme that can perform proteolysis or breakdown of proteins into smaller polypeptides and amino acids. The digestive enzymes Pepsin, Trypsin and Chymotrypsin break down the proteins in food in the human digestive system. Renin plays an important role in the digestion of casein (milk protein) in newborns. Thus, the correct answer is option D.

Question 5

What is common among amylase, rennin and trypsin?

Accepted Answer

The common feature between rennin, amylase and trypsin are that these are protein enzymes. They act on the substrates starch , protein and lactose respectively.

Question 6

The literal meaning of "gastrulation" is

Accepted Answer

'Gastrulation' word is derived from Greek word 'gaster' meaning stomach and according to McEwen (1923), gastrulation refers to the formation of the primordial gastric gut or cavity called the archenteron.

Question 7

A patient is generally advised to specially consume more meat, lentils, milk and eggs in diet only when he suffers from -

Accepted Answer

$\textbf{Correct answer: C}$ $\textbf{Option (A):}$ $\bullet$ If a person suffers from anaemia then they are advised to consume more food rich in iron. $\bullet$ This is because iron is required for the generation of haemoglobin. $\textbf{Option (B):}$ $\bullet$ Scurvy is caused due to deficiency of Vitamin C. The food material that is rich in vitamin C is prescribed to such patients. $\textbf{Option (C):}$ $\bullet$ Kwashiorkor occurs due to the deficiency of protein. $\bullet$ Such patients are prescribed a diet containing food materials like meat, lentils, milk and eggs which are rich in proteins. $\textbf{Option (D):}$ $\bullet$ The deficiency of Vitamin D3 and Calcium causes rickets. $\bullet$ Due to abnormal growth of the bones patients are prescribed to include food in their diet which is rich in calcium. Hence, the correct answer is option (C).

Question 8

Which of the following controls the peristaltic movement ofthe intestine?

Accepted Answer

Auerbach's plexus is the part of the autonomic nervous system in vertebrates lying between the two main muscular layers of the intestine and controlling its peristaltic movements.

Question 9

Which is the characteristic lining of stomach of mammals

Accepted Answer

The mucosa is highly folded and the single-layered mucous membrane of the in foldings forms tubular and and often branched gastric gland in the lamina propria. Each gland has three types of secretory cells - neck cells, oxyntic cells, zymogen cells.

Question 10

The cup-shaped cavity for the articulation of the head of thefemur is called

Accepted Answer

Acetabulum is made up of Parts of ilium, ischium and pubis. It provides articulation for head of femur.
