Questions Related to tissues of animals

Which of the following statement is $NOT$ $CORRECT$ about the compound epithelium?
I.   It consist of several layers
II.  It covers the dry surface of the skin, the moist surface of buccal cavity, inner lining of ducts of salivary glands and pancreatic ducts
III.  It provides protection against chemical and mechanical stresses 
IV.  Being multilayered it has a great role in secretion and absorption

  1. Only III

  2. Only IV

  3. Only I and IV

  4. Only II


Correct Option: B
Explanation:
Compound epithelium has a limited role in secretion and absorption. So, the correct option is "only IV".

Our outer layer of skin is an example of which type of tissue?

  1. Muscular

  2. Epithelial

  3. Connective

  4. Nervous


Correct Option: B
Explanation:

Our outer layer of skin is made up of epithelial tissues. The epidermis is composed of the outermost layers of cells in the skin.

The epithelial tissue present on the inner surface of bronchi oles and fallopian tubes is :

  1. Squamous

  2. Cuboidal

  3. Glandula

  4. Cilia ted


Correct Option: D
The cell junctions namely tight, adhering and gap junctions are found in ______________.
  1. connective tissues

  2. epithelial tissues

  3. neutral tissues

  4. muscular tissues


Correct Option: B
Explanation:

Cell junctions are proteins that connect the cytoplasmic content of adjacent cells, they form a barrier between two cells and also hold or adhere cell together or with the extracellular matrix. these are abundant in epithelial tissue.

So, the correct answer is 'epithelial tissues'

Read the following statements regarding different types of animals tissues and select the incorrect ones.
(i) Each fasciculus (or bundle of muscle fibres) is surrounded by an epithelial tissue covering called perimysium
(ii) Multi unit smooth muscles are present in ciliary and iris muscles in the eyes and muscles of the walls of large blood vessels.
(iii) Columnar epithelium present in gastric glands, intestinal glands and pancreatic lobules, has a secretory role and is called as glandular epithelium.
(iv) Epithelial tissue arises only from the ectoderm of embryo and is usually supplied with blood vessels
  1. (i) and (iii)

  2. (ii) and (iii)

  3. (ii) and (iv)

  4. (i) and (iv)


Correct Option: D
Explanation:

Each fasciculus (bundle of muscle fibres) is surrounded by a connective tissue sheath called perimysium. Epithelial tissues arise from all the three primary germ layers of the embryo i.e., ectoderm, mesoderm and endoderm.

Stratum germinativum is an example of which kind of epithelium?

  1. Columnar

  2. Squamous

  3. Cuboidal

  4. Ciliated


Correct Option: C
Explanation:
The stratum germinativum is the deepest layer of the five layers of the epidermis. The stratum basale is a single layer of columnar or cuboidal cells.
So, the correct option is 'cuboidal'.

Mammary glands are a part of 

  1. Epithelial tissue

  2. Connective tissue

  3. Skeletal tissue

  4. Muscular tissue


Correct Option: A
Explanation:

Mammary glands are a modification of the epithelial layer or epithelial tissue. They are formed of the glandular epithelium.

So, the correct option is 'Epithelial tissue'.

Which tissue found on upper surface of skin?

  1. Epidermis

  2. Endodermis

  3. Cuboidal Cells

  4. Connective tissues


Correct Option: A
Explanation:

Tissues found on the upper surface of the skin is epidermis and dermis is found beneath it.

The epithelium which forms the inner wall of blood vessels is_____________

  1. Cuboidal epithelium

  2. Ciliated epithelium

  3. Squamous epithelium

  4. Compound epithelium


Correct Option: C
Explanation:
  • The simple squamous epithelium that lines the blood vessels is called the endothelium. The endothelium is the thin layer of cells that line the interior surface of blood vessels, forming an interface between circulating blood in the lumen and the rest of the vessel wall. Endothelial cells line the entire circulatory system, from the heart to the smallest capillary. These cells reduce turbulence of the flow of blood allowing the fluid to be pumped farther. 
Endothelial tissue is a specialized type of epithelium tissue (one of the four types of biological tissue in animals). More specifically, it is a simple squamous epithelium.
