Which of the following organs contain(s) smooth muscles?

  1. Blood vessels

  2. Iris of the eye

  3. Bronchi

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Smooth muscles are spindle-shaped and are under involuntary control. They are seen in the internal organs such as the blood vessels, iris and the lung bronchi. In the blood vessels, they enable the blood flow. In iris, they increase the pupil size in the presence of bright light. They help in lung contraction and relaxation due to their presence in bronchioles. Thus the correct answer is option D.

Which of the following tissues is made up of long contractile cells packed with actin and myosin microfilaments?

  1. Epithelial tissue

  2. Adipose tissue

  3. Fibrous connective tissue

  4. Nervous tissue

  5. Muscle tissue
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Muscles contract via the action of proteins actin and myosin. Both these proteins are present as microfilaments. Actin forms the thin filaments of muscle cells and myosin forms the thick filaments.

So, the correct answer is 'Muscle tissue'.

Mast cells occur in ______________.

  1. Areolar tissue

  2. Adipose tissue

  3. White fibrous tissue

  4. Yellow fibrous tissue
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mast cells are immune cells that release histamine and heparin; they are commonly found in connective tissues, specifically areolar tissue.

Which of the following cells are found in areolar tissue?

  1. Mast cells

  2. Plasma cells

  3. Histiocytes

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Areolar Tissue is a common form of loose connective tissue. Areolar tissue is found in many locations around the body.

Areolar Tissue is loose connective tissue that consists of a meshwork of collagen, elastic tissue, and reticular fibres - with many connective tissue cells in between the meshwork of fibres.
The fibres that form the mesh structure of areolar tissue include:

Collagen fibres, elastic fibres, reticular fibres
The different types of cells embedded within the areolar tissue include:
Fibroblasts, plasma cells, adipocytes, mast cells and macrophages (The histiocyte is a tissue macrophage). 

So the answer 'All of these'.

Different types of cells are given below.

[Hepatocytes, WBC's, Basophils, Fibroblasts, Plasma cells, Mast cells, Osteocytes, Chondrobiasts.]

Identify the cells that are found embedded in the matrix of areolar tissue and select the correct option.

  1. Fibrobiasts, Hepatocytes, Mast cells, Osteocytes

  2. WBC's, Basophils, fibrobiasts, Mast cells, Plasma cells

  3. Fibrobiasts, WBC's , Plasma cells, Mast cells

  4. Fibrobiasts, WBC's, Chondrobiasts, Mast cells
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Areolar tissues are widely distributed connective tissue in the animal body. It is named because so because it takes the form of fine threads crossing each other in every direction leaving small spaces called areolae. 
  • The areolar tissue consists of ground substance, the matrix, white yellow and reticular fibers and cells like fibroblasts, hepatocytes, mast cells and osteocytes.

So the correct answer is 'Fibroblasts, hepatocytes, mast cells, osteocytes'.
