Question 1
1 / -0

Which of the following statements is true about muscle?

A
Skeletal muscle is an involuntary muscle.

B
Smooth muscle is striated.

C
Cardiac muscle is a voluntary muscle.

D
None of the above

Solution

Skeletal muscle is a voluntary muscle whereas, cardiac muscle is an involuntary muscle. Smooth muscles do not possess alternate dark and light bands. Hence. smooth muscles are unstriated.
None of the statements are correct.
Thus, the correct answer is option D.
Question 2
1 / -0

Immunocomplexes are removed by

A
Basophils and monocytes

B
Basophils and eosinophils

C
Eosinophils and monocytes

D
Neutrophils and basophils

Solution

Immunocomplexes also called antigen-antibody complexes are harmful and long deposition of then inside the cell can lead to various autoimmune disorders and primarily removed from the cell by phagocytosis in which eosinophils and monocytes (destruction of antibody) have an important role to play.
So the correct option is 'Eosinophils and monocytes'.
Question 3
1 / -0

Name the part of the neuron, where information is acquired.

A
Axon

B
Dendrites

C
Synapse

D
Schwann cells

Solution

Neuron is a structural and functional unit of neural system. It is composed of three major parts- cell body, dendrites and axon.
A. Axon is a long fibre which arises from the cell body and terminates as a bulb-like structure called the synaptic knob which participate in synapse. Hence, the axons take away the information from the cell body of the neuron to which they belong.
B. Dendrites are the short fibers which arise out from the cell body. The dendrites of one neuron receive the electrical impulses from different sources and then transmit these impulses towards the cell body of the neuron to which they belong. Hence, the information is acquired here.
C. Synapse is the nerve impulse which is transmitted from one neuron to another through the junctions. It is formed by the membranes of the pre-synaptic neuron and a post-synaptic neuron.
D. Schwann cells are enclosed in myelin sheath and are lipid rich cells.
So, the correct option is 'Dendrites'.
Question 4
1 / -0

Mast cells contain vesicles that store large amounts of histamine. After staining with eosin, these vesicles are stained red in color. Identify which of the following interactions is involved between histamine and eosin?

A
Hydrophobic interaction

B
Electrostatic interaction

C
Covalent bonding

D
Hydrogen bonding

Solution

Eosin is the most common dye to stain the cytoplasm in histology. It is an acidic dye that binds to basic components of a cell, mainly proteins located in the cytoplasm. It gives a bright pink color that contrasts the dark blue nuclear hematoxylin staining Arginine, histidine, and lysine (at both acidic and neutral pH) and tryptophan (at acidic pH) residues of a protein bind electrostatically to carboxylic and phenolic groups of the dye to produce a stable water-soluble protein-dye complex. As Histamine is protein, Eosin and Histamine bind due to electrostatic interaction and gives red color.

So, the correct answer is “Electrostatic interaction”.
Question 5
1 / -0

Which of the following muscles is present in the urinary bladder?

A
Smooth muscles

B
Skeletal muscles

C
Striated muscles

D
Cardiac muscles

Solution

The muscle present in the urinary bladder is called 'detrusor muscle' and is a smooth muscle mostly present in the walls of the bladder. It is a single-unit smooth muscle as the whole bundle contacts in order to perform various functions of the organ. These muscles relax in order to store urine in the bladder and contract when urine is to be released.
So, the correct answer is option A.
Question 6
1 / -0

Which of the following cells are found in areolar tissue?

A
Mast cells

B
Plasma cells

C
Histiocytes

D
All of these

Solution

Areolar Tissue is a common form of loose connective tissue. Areolar tissue is found in many locations in the body. It 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'.
Question 7
1 / -0

Centrosome includes a pair of centrioles that help in cell division by spindle formation. The non-dividing cells in human are

A
Chondrocytes

B
Epithelial cells

C
Neurons

D
Neuroglial cells

Solution

A. Chondrocytes are the cells that are found in cartilage. These cells can divide forming a nest of 2-4 cells.
B. Epithelial cells are the cells lining the surfaces of the body. These cells can also divide by mitosis.
C. Neurons or the nerve cells are the largest cells in the body and found in the nervous system. These cells do not have centrioles and hence, do not undergo cell division.
D. Neuroglial cells are the cells in the central nervous system, other than neurons. These cells are meant for the protection of neurons and can divide by mitosis.
Hence, non-dividing cells in humans are neurons.

So, the correct answer is 'Neurons'.
Question 8
1 / -0

A student was asked to observe a slide of skeletal muscle fiber under the microscope. The correct diagrams(s) given below that resemble(s) the slide of skeletal muscle is/are

A
Only B

B
Only A

C
Both A and C

D
Only D
Solution
Skeletal muscles have the following features:
These are striated due to the presence of sarcomere.
These are unbranched
The cells are multinucleate
These are cylindrical in shape
These features are shown in image D.
Image A shows smooth muscles that are spindle-shaped and non-striated.
Image B shows cardiac muscles that are striated, branched and uni-nucleate.
Image C does not resemble any muscle. It is enucleated.
Image D shows the striated, multi-nucleated, unbranched fibers that are skeletal muscles.
Hence, the correct answer is 'D'
Question 9
1 / -0

Select the correct option regarding A' or 'B' given in the flow charts

A
'A' is cell and 'B' is tissue

B
'A' is unicellular and B is multicellular

C
'A' is tissue and B is cell

D
None of the above
Solution
- The flow chart illustrates the structural organisation or level of organisation in an organism.
- A is cell- structural and functional unit of life.
- B is a tissue- group of cells form tissues.
- C is an organ- similar tissues come together to form a specific organ.
- D is an organ system- organs combine to form differetn systems in an organism.
- E is an organism- different organ systems form an organism.
- The correct answer is OPTION A.
Question 10
1 / -0

The type of junction that prevents separation of the cardiac cells during its functioning is

A
Tight junction

B
Adhering junction

C
Gap junction

D
Zonula occludens

Solution

Cardiac muscle cells are rectangular shaped cells connected by regions called intercalated discs. The gap junctions, which are protein-lined tunnels, allow direct transmission of the depolarizing current from cell to cell, across the chambers of the heart, so that the cells contract in unison.
So the correct answer is 'Gap junction'.
