ANIMAL TISSUES (EPITHELIAL TISSUE, MUSCULAR TISSUE & NERVOUS TISSUE): DAILY PRACTICE PAPER (DPP) BY TEACHINGCARE.COM

 

1. 1. Which of the following statements w.r.t. epithelial tissue is not true ?

 

1. This tissue has a free surface, which faces either a body fluid or the outside

environment and thus provides a covering or a lining for some part of the

body.

2. The cells are loosely packed with little intercellular matrix.

3.There are two types of epithelial tissues namely simple epithelium and

compound epithelium.

4. Simple epithelium is composed of a single layer

of cells and functions as a lining for body cavities, ducts, and tubes.

Ans 2

2. Which of the following diagrams represents squamous epithelium ?

 

(a)

 

 

 

 

(b)

 

 

 

 

 

(c)

 

 

(d)

Ans 1

3. Which of the following statements w.r.t. cell junctions is incorrect ?

 

1. Three types of cell junctions

are found in the epithelium and other tissues.

2. Tight junctions help to stop substances

from leaking across a tissue.

3.Adhering junctions perform cementing to

keep neighbouring cells together.

4.Gap junctions facilitate the cells to

communicate with each other by connecting the cytoplasm of adjoining

cells, for rapid transfer of ions, all molecules.

Ans 4

4. The columnar epithelium is

composed of a single layer of tall and slender cells. Their nuclei are located

at the base. Free surface may have microvilli. They are found in the lining of

1. stomach and intestine
2. Pancreas
3. Tongue
4. Spleen

Ans. 1

 

5.The following are the characteristic features of ciliated epithelia except

1. They are composed of columnar or cuboidal cells bearing cilia on their free surface.

2.Their function is to move particles of mucus in a specific direction over the epithelium.

3. Their function is to move particles of mucus in a all directions over the epithelium

4.They are mainly present in the inner surface of hollow organs like bronchioles and fallopian tubes.

Ans.3

 

6 Some of the columnar or cuboidal cells

get specialised for secretion and are called

glandular epithelium . The

unicellular, mucus secreting cells belong to

1.salivary gland

2. goblet cells of the alimentary canal
3. Pancreas
4. Thyroid

Ans 2

7. Exocrine

glands secrete

1. mucus, saliva,
2. earwax, oil,
3. milk, digestive enzymes
4. All of the above

Ans 4

 

8. Compound epithelium is made of more

than one layer (multi-layered) of cells and is found in

1. the dry surface of the skin, the moist surface of buccal cavity and pharynx.
2. inner lining of ducts of salivary glands
3. inner lining  of pancreatic ducts
4. All of the above
5. Ans 4

 

 

9. Communication junctions at some fusion points allow the cells to contract as a

unit, i.e., when one cell receives a signal to contract, its neighbours are

also stimulated to contract.Such .  Communication junctions are found in

1. Skeletal muscles
2. Smooth muscles
3. Cardiac muscle
4. Both 2 and 3

 

10. Choose the correct statement w.r.t. neuroglia

 

1. The neuroglial cell which constitute the rest of

the neural system protect and support

neurons.

1. Neuroglia make up more than one half

the volume of neural tissue in our body.

1. Only 1
2. Both 1 and 2

 

11. The diagramme given below corresponds to

 

 

1. Skeletal muscle
2. Smooth muscle
3. Cardiac muscle
4. Collagen fibres

Ans 3

 

 

 

 

 

12.What do  black spots, outside a large neuron , represent in the diagramme of a neural tissue given below

 

 

1. Nuclei of a neurons
2. Nissle’s granules
3. Neuroglial cells
4. Glycogen granules

Ans. 3

 

13. A muscle is made of many long, cylindrical fibres

arranged in parallel arrays. These fibres are composed of

numerous fine fibrils, called myofibrils. This is true w.r.t.

1. Skeletal muscle
2. Smooth muscle
3. Cardiac muscle
4. All of the above

Ans 4

14. The wall of internal organs such as the blood vessels, stomach and intestine contains a type

of involuntary muscle tissue which is represented in the diagramme

 

 

 

 

 

 

 

 

 

 

 

 

 

1. Both 1 and 3

 

Ans 2

 

15. Which of the following statement(s) is/are not false

 

1. All cells in epithelium are held together with little intercellular material.

 

1. In nearly all animal tissues, specialised junctions provide both structural

and functional links between its individual cells.

1. Three types of cell junctions are found in the epithelium and other tissues namely tight junctions,

adhering junctions and gap junctions.

 

1. All the above
