Question 1
1 / -0

Muscles of heart are

A
Striated and voluntary

B
Nonstriated and voluntary

C
Striated unbranched and involuntary

D
Nonstriated and involuntary

E
Striated, branched and involuntary
Solution
Correct Answer: E
Explanation:
The muscles of the heart are called the cardiac muscles or myocardium which is responsible for the pumping of the heart all the time.
Thus, the muscle of the heart is involuntary in nature.
It is striated and branched and its function is regulated by the autonomous nervous system.
Hence, the correct answer is Striated, branched, and involuntary.
Question 2
1 / -0

Yellow colour of faeces is on account of:

A
Excessive turmeric

B
Bile

C
Degradation product of haemoglobin

D
None of the above

Solution

Liver produces bile salts which have pigments called Bilirubin and Biliverdin, They are formed by the degradation of the hemoglobin, they impart the yellow colour to the faeces.
Thus, the correct answer is option C.
Question 3
1 / -0

Muscle fibres having rounded ends are

A
Unstriated muscles

B
Smooth muscles

C
Striated muscles

D
All the above

Solution

Striated muscles include skeletal muscles and cardiac muscles. Both of them are cylindrical in shape and hence have rounded ends. Smooth muscles are unstriated and spindle shaped.
Hence the correct option is C.
Question 4
1 / -0

End plate junction is present between:

A
Neuron and striated muscle

B
Neuron and neuron

C
Muscle and muscle

D
Both B and C

Solution

End plate junction or neuromuscular junction, are specialized chemical synapses formed at the sites where terminal branches of a motor neuron is able to contact the target muscle cell (skeletal muscle) and is achieved by the secretion of acetylcholine.
Thus, the correct option is "neuron and striated muscle".
Question 5
1 / -0

Smooth muscles are found in all the sites mentioned below except:

A
Alimentary tract

B
Uterus

C
Oviduct

D
External muscle of the eye ball

Solution

Smooth muscles are involuntary muscles present in the alimentary canal, uterus, oviduct etc.
So, the correct option is D.
Question 6
1 / -0

In the given diagram of a section of bone tissue, certain parts have been indicated by alphabets. Select the answer in which these alphabets have been correctly matched with the parts which they include.

A
A- Interstitial lamellae; B- Nerve; C- Canaliculi; D- Haversian canal

B
A- Intestitial lamellae; B- Osteocytes, C- Haversian system; D- Canaliculi

C
A- Intestitial lamellae; B- Osteocytes; C- Nerve; D- Blood vessels

D
A- Intestitial lamellae; B- Osteocytes; C- Haversian canal; D- Endosteum

Solution

A - Interstitial lamellae
B - Osteocytes
C - Haversian canal
D - Endosteum
So, the correct answer is 'A- Intestitial lamellae; B- Osteocytes; C- Haversian canal; D- Endosteum'.
Question 7
1 / -0

Consider the following statements (i)- (iii), each with one or two blanks.
(i) Bones have a hard and non-pliable ground substance rich in _____ (1) and _____ (2) which give bone its strength,
(ii) Some of the columnar or cuboidal cells get specialised for secretion and are called ______ (3) epithelium
(iii) ______ (4) junctions help to stop substances from leaking across a tissue.
Which one of the following option, gives the correct fill ups for the respective blanks from (1) to (4) in the statements?

A
(3)- glandular; (4)- Tight

B
(1)- calcium salts; (2) collagen fibres; (3)- compound; (4)- Excretory

C
(3)- glandular; (4)- Adhering

D
(1)- magnesium salts; (2) elastic fibres; (3)- compound

Solution

(i) Bones have a hard and non-pliable ground substance rich in (1) 'calcium salts' and (2) 'collagen fibres' which give bone its strength.
(ii) Some of the columnar or cubical cells get specialised for secretion and are called (3) 'glandular' epithelium.
(iii) (4)'Tight' junctions help to stop substances from leaking across a tissue.
So, the correct answer is '(3)- glandular; (4)- Tight'.
Question 8
1 / -0

People who have migrated from the planes to an area adjoining Rohtang Pass about six months back :

A
Have more RBCs and their haemoglobin has a lower binding affinity to $$O_2$$

B
Are not physically fit to play games like football.

C
Suffer from attitude sickness with symptoms like nausea, fatigue, etc.

D
Have the usual RBC count but their haemoglobin has very high binding affinity to $$O_2$$
Solution
Correct Option: A

Explanation:
- In order to increase the delivery of oxygen to muscles, the RBC count is increased.
- To allow easy release of oxygen to cells, affinity of oxygen to haemoglobin is decreased.
- In duration of 6 months, people become adapted to the environment in which they live. Since the production of RBCs is increased, people are physically fit to play games like football.
- People will suffer from exhaustion, nausea and fatigue for 1 to 3 days, but after some time they adjust to the environment.
Hence, people who have migrated from the planes to an area adjoining Rohtang Pass about six months back have more RBCs and their haemoglobin has a lower binding affinity to O_2.
Question 9
1 / -0

Select the correct statement regarding the Schwann cells.

A
Surround axon of myelinated nerve fibre

B
Support muscle fibres

C
Found in Haversian system of bones

D
Form basement membrane of epithelium.

Solution

A Schwann cell forms a myelin sheath by wrapping its plasma membrane concentrically around the axon of nerve cells.
Nerves having myelin sheath are called myelinated neurons.
So, the correct answer is option A.
Question 10
1 / -0

Serum differs from blood in lacking

A
Globulins

B
Albumins

C
Clotting factors

D
Antibodies

Solution

Blood is composed of a clear, straw coloured, watery fluid called plasma in which different types of blood cells are suspended.
Serum is that part of blood which is similar in composition with plasma but does not contain clotting factors of blood. It includes all proteins not used in blood clotting and all the electrolytes, antibodies, antigens, hormones, etc.
So, the correct option is C.
