Pseudo stratified epithelium is present in

  1. Urinary bladder

  2. Nephron

  3. Larynx

  4. Trachae

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pseudostratified columnar epithelium lines the respiratory tract, including the trachea (misspelled as 'Trachae' in options). This epithelium appears stratified but all cells contact the basement membrane, with cilia that move mucus.

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

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Compound epithelium has a limited role in secretion and absorption. So, the correct option is "only IV".

  1. Muscular

  2. Epithelial

  3. Connective

  4. Nervous

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

  1. Squamous

  2. Cuboidal

  3. Glandula

  4. Cilia ted

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bronchioles and fallopian tubes require ciliated epithelium to move particles or ova. Cilia beat rhythmically to transport mucus in respiratory tract and egg cells in the female reproductive tract.

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

  2. epithelial tissues

  3. neutral tissues

  4. muscular tissues

Reveal answer Fill a bubble to check yourself
B Correct answer
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)

Reveal answer Fill a bubble to check yourself
D Correct answer
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.
