Correct Option: D

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

tissues of animals tissues: plant and animal tissues animal tissues structure of living organisms biology cell division in embryo development division for growth and reproduction

  1. Only III

  2. Only IV

  3. Only I and IV

  4. Only II

Show answer
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?

tissues of animals tissues: plant and animal tissues animal tissues structure of living organisms biology cell division in embryo development division for growth and reproduction

  1. Muscular

  2. Epithelial

  3. Connective

  4. Nervous

Show answer
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

Show answer
Correct Option: D
The cell junctions namely tight, adhering and gap junctions are found in ______________.
tissues of animals tissues: plant and animal tissues animal tissues structure of living organisms biology cell division in embryo development division for growth and reproduction

  1. connective tissues

  2. epithelial tissues

  3. neutral tissues

  4. muscular tissues

Show answer
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)

Show answer
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.

Muscular tissues which function throughout the life continuously without fatigue is______________

biology tissues: plant and animal tissues tissues of animals animal tissues and its type tissues: animal tissues fluid connective tissue

  1. Skeletal muscle

  2. Smooth muscle

  3. Cardiac muscle

  4. Voluntary muscle

Show answer
Correct Option: C
Explanation:
  • Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart. 
  • This is a specialized muscle that, while similar in some fundamental ways to smooth muscle and skeletal muscle, has a unique structure and with an ability not possessed by muscle tissue elsewhere in the body. 
  • Cardiac muscle, like other muscles, can contract, but it can also carry an action potential (i.e., conduct electricity), like the neurons that constitute nerves.
  •  Furthermore, some of the cells have the ability to generate an action potential, known as cardiac muscle automaticity. Cardiac muscle is adapted to be highly resistant to fatigue:
  •  it has a large number of mitochondria, enabling continuous aerobic respiration, numerous myoglobins (oxygen-storing pigment), and a good blood supply, which provides nutrients and oxygen.
