Weekly Quiz Competition
  • Question 1
    1 / -0
    Match the terms listed with the structures where they occur. Choose the answer, which gives the correct combination of alphabets of the two columns.
    Structure
    Occurrence
    A. Haversian canal
    p. Kidney
    B. Dendrites
    q. Cartilage
    C. Sarcolemma
    r. Muscle
    D. Chondrocytes
    s. Nerve cells

    t. Bone

    Solution
    Each osteon consists of concentric layers of compact bone tissue, that surround a central canal called the Haversian canal. So, option 'A' matches with option 't'. Dendrites are the short cytoplasmic processes of the cell body of the neuron, which receives stimulus from other neurons. So, option 'B' matches with option 's'. Sarcolemma is the cell membrane of a striated muscle fiber. So, option 'C' matches with option 'r'. Chondrocytes are the only cells in healthy cartilage. So, option 'D' matches with option 'q'.
    Thus, the correct answer is the option (C), 'A  t, B  s, C  r, D  q'.
  • Question 2
    1 / -0
    Fat deposits are found in:
    Solution
    Adipose tissue is a loose connective tissue composed mostly of adipocytes or fat cells. These help in the protection of vital organs and act as an insulating layer.
    So, the correct answer is option C.
  • Question 3
    1 / -0
    Areolar connective tissue joins:
    Solution
    answer:
    Correct Answer: C
    Explanation:
    • Areolar connective tissue is a type of connective tissue whose main function is to bind the various part together.
    • It is a loose connective tissue which binds skin epithelia with muscles or it also binds with nerves and blood vessels.
    • It mainly attaches the surface epithelial layer with the underlying layers.
    Hence, the areolar connective tissue joins skin with muscle.
  • Question 4
    1 / -0
    Mast cells of connective tissue release
    Solution
    A  mast cell  is derived from the myeloid stem cell and contains many granules rich in histamine and heparin. Mast cells play an important role in allergy and anaphylaxis and are involved in wound healing and defence against pathogens. So, the correct answer is option B.
  • Question 5
    1 / -0

    Which of the following tissues lines the blood vessels?

    Solution

    Blood vessels are lined by single-layered simple squamous epithelium tissue called the endothelium. The endothelium is the thin layer of cells that line the interior surface of blood vessels. It helps in the exchange of materials like gases and nutrients between the blood and the body tissues.

    Thus, the correct option is B.

  • Question 6
    1 / -0
    Match the type of connective tissues listed under column I with the functions listed under column II. Choose the choice, which gives the correct combination of the alphabets of the two columns.
    Connective tissues
    Functions
    A. Ligament
    p. Stores fat
    B. Tendons
    q. Connects bone to bone
    C. Areolar tissue
    r. Connects muscle to bone
    D. Adipose tissue
    s. Forms blood cells

    t. Filling tissue
    Solution
    • The ligament is the fibrous tissue that connects bones to other bones. 
    • Tendon is a tough band of fibrous connective tissue that connects muscle to bone. 
    • Areolar tissue is the connective tissue with fibres arranged in a mesh or net and acts as a filling tissue. 
    • Adipose tissue or body fat or simply fat is a loose connective tissue composed of adipocytes or fat cells, which stores fats. 
    So, the correct answer is option A.
  • Question 7
    1 / -0
    Match the types of the animal tissues with the parts / organs in which they occur. Choose the answer, which gives the correct combination of the alphabets of the two columns.
    Tissue
    Part / organ
    A. Squamous epithelium
    p. Below the skin
    B. Hyaline cartilage
    q. Bowman's capsule
    C. Adipose tissue
    r. Walls of stomach
    D. Smooth muscles
    s. Trachea

    t. Duct of glands

    Solution
    Squamous epithelium cells are composed of a large flat whose edges it closely together like the tiles in a floor and it forms the wall of Bowman's capsule. Hyaline cartilage is a translucent, slightly elastic matrix with less fibre and forms a ring of the trachea. Adipose tissue is a fat-storing tissue which is present below the skin. Smooth muscles are involuntary muscles. It composes of muscles of internal organs and the digestive system. Thus, the correct answer is D.
  • Question 8
    1 / -0
    What is diapedesis?
    Solution
    Diapedesis is the squeezing movement of WBC at the site of infection.
    It can be defined as the passage of blood, or any of its formed elements, through the intact walls of blood vessels. White blood cells (WBCs), also called leukocytes are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. All white blood cells are produced and derived from multipotent cells in the bone marrow known as hematopoietic stem cells. Leukocytes are found throughout the body, including the blood and lymphatic system.
    Hence the correct option is C.

  • Question 9
    1 / -0
    Match the names with the tissues shown. Choose the answer, which gives the correct combination of the alphabets.
    Cells
    Tissues
    A. Erythocytes
    p. Bone
    B. Chondrocytes
    q. Neuron
    C. Osteocytes
    r. Cartilage
    D. Schwann cells
    s. Blood

    t. Adipose tissue
    Solution
    Erythrocytes are the red blood cells and are the most common type of blood cells. 
    Chondrocytes are the only cells found in healthy cartilage. 
    The osteocyte is a star-shaped cell and is most commonly found in mature bones. 
    The myelin sheath of the neuron is formed by Schwann cells and each Schwann cell covers a part of the axon. 
    Thus, the correct answer is option B. 
  • Question 10
    1 / -0
    Polycythaemia is 
    Solution
    Polycythemia is a disease state in which the proportion of blood volume that is occupied by red blood cells increases. Blood volume proportions can be measured as hematocrit level. It can be due to an increase in the number of red blood cells or to a decrease in the volume of plasma.
    So, the correct answer is option B.
