Weekly Quiz Competition

Question 1
1 / -0

Touch on the right side stimulate

A
Right somatic sensory area

B
Right somatic motor area

C
Left somatic sensory area

D
Both B and C

Solution

C. Left somatic sensory area
Reason: Human brain is divided into two parts, the left cerebral hemisphere, and the right cerebral hemisphere. The left cerebral hemisphere controls the right portion of the body and the left portion is controlled by the right hemisphere. So the stimulation that arises from the touch will stimulate the left somatic sensory area and vice versa. So the correct option is C.
Question 2
1 / -0

Choose the correct option about a - d.

A
a - eosinophil, b - lymphocyte, c - neutrophil, d - monocyte

B
a - erythrocyte, b - basophil, c - neutrophil, d -lymphocyte

C
a - eosinophil, b - monocyte, c - neutrophil, d - lymphocyte

D
a - eosinophil, b - erythrocyte, c - neutrophil, d- basophil
Solution
Correct Option: C
Explanation:
In the diagram,
a- depicts eosinophils, which are granulocytes with a bilobed nucleus.
b -denotes monocytes, which are agranulocytes with a kidney-shaped nucleus.
c- denotes neutrophils, which are granulocytes with a 2-5 lobed nucleus.
d -denotes lymphocytes, which are agranulocytes with a big concentrated nucleus.
Hence, the correct option about a-d is as follows, 'a - eosinophil, b - monocyte, c - neutrophil, d - lymphocyte'.
Question 3
1 / -0

RBC count is higher in

A
New born babies

B
Persons living in hilly areas

C
Persons suffering from respiratory ailments

D
All the above.

Solution

A. New born babies
Reason: Infants have fetal hemoglobin, where has more affinity for oxygen than the hemoglobin found in adults. So, due to more affinity, oxygen binding will also be strong. The amount of oxygen released by RBC at the tissue level is deceased. So in order to compensate for the decreased oxygen availability the number of RBCs is increased.

Question 4

1 / -0

In terms of descending order of percentage proportions of leucocytes in human blood, which one is correct?

Neutrophils $$\to$$ lymphocytes $$\to$$ monocytes $$\to$$ acidophils $$\to$$ basophils

Neutrophils $$\to$$ basophils $$\to$$ lymphocytes $$\to$$ acidophils monocytes

Neutrophils $$\to$$ monocytes $$\to$$ lymphocytes $$\to$$ acidophils $$\to$$ basophils

Neutrophils $$\to$$ acidophils $$\to$$ basophils $$\to$$ lymphocytes $$\to$$ monocytes

Solution

Cells

Percentage proportion of
total leucocyte count

$$Cells/mm^3$$ of blood

Neutrophils

60-70%

4000-5000 cells/$$mm^3$$

Lymphocytes

20-40%

1500-2500 cells/$$mm^3$$

Monocytes

2-7%

200-700 cells/$$mm^3$$

Acidophils

1-5%

70-300 cells/$$mm^3$$

Basophils

0.5-2.7%

35-150 cells/$$mm^3$$

Thus, the correct answer is (A).

Question 5
1 / -0

Both RBC and WBC are formed in the

A
Thymus

B
Adrenal

C
Throid

D
Bone marrow

Solution

In adults, RBC and WBC are produced in the bone marrow of long bones. In the embryo, the liver is the main site of red blood cell production.
So, the correct option is 'Bone Marrow'.
Question 6
1 / -0

The cells lining the blood vessels belong to the category of ____________.

A
Columnar epithelium

B
Squamous epithelium

C
Cuboidal epithelium

D
Connective tissue
Solution
Correct Answer: B
Explanation:
Squamous epithelium or pavement epithelium is a type of simple epithelial tissue.
It is formed of a single layer of closely fitted, flattened, polygonal cells that develop bulges in the region of their nuclei.
The adjacent cells are held together with help of various types of junctions, commonly tight junctions.
The cells of squamous epithelium appear as tiles on the floor due to their attachment to the basement membrane by hemidesmosomes.
It occurs in the lining of various components of the blood vascular system, pericardial cavity, abdominal cavity, alveoli of lungs, etc.
Hence, the correct answer is Squamous epithelium.
Question 7
1 / -0

Fibroblasts, macrophages and mast cells are present in

A
Cartilage tissue

B
Adipose tissue

C
Areolar tissue

D
Glandular epithelium
Solution
1. Cartilage is made up of specialized cells called chondrocytes. These chondrocytes produce large amounts of extracellular matrix composed of collagen fibers, proteoglycan, and elastin fibers.
2. Adipose tissue is loose connective tissue composed of fat cells known as adipocytes. Adipocytes contain lipid droplets of stored triglycerides.
3. The different kinds of cells present in areolar connective tissue are macrophages, mast cells, adipocytes, fibroblasts and plasma cells.
4. Glandular epithelium covers the endocrine and exocrine glands of the body. The main function is secretion.
So, the correct option is 'Areolar Tissue'.
Question 8
1 / -0

Bone is mainly composed of:

A
Iron and phosphorus

B
Sulphur and calcium

C
Calcium and phosphorus

D
Calcium and magnesium
Solution
- The bone is mainly composed of calcium and phosphorus. The bone is a hard connective tissue.
So, the correct answer is option C.
Question 9
1 / -0

During depolarisation of neuron

A
$$K^+$$ channels remain open

B
N$$a^+$$ gets inside through ion channels

C
N$$a^+$$ gets outside through ion channels

D
All the above

Solution

The depolarization, also called the rising phase, is caused when positively charged sodium ions (Na+) suddenly rush through open voltage-gated sodium channels into a neuron. As additional sodium rushes in, the membrane potential actually reverses its polarity.
Hence the correct option is B.
Question 10
1 / -0

Papillary muscles are found in mammalian _______.

A
Auricles

B
Ventricles

C
Pinna

D
Eyes

Solution

The papillary muscles are the involuntary muscles which are present in the ventricles of the mammalian heart. They support the tricuspid valves and mitral valves. The contraction of the papillary muscles opens these valves and when the papillary muscles relax, the valves get closed. Chordae tendineae connects the papillary muscles to the valves.
So, the correct answer is option B.
