Question 1
1 / -0

What is the type of movable joint present between the atlas and axis?

A
Saddle

B
Pivot

C
Hinge

D
Gliding

Solution

Pivot joint: Between atlas and axis called atlanto-axial joint.
Question 2
1 / -0

The property which doesn’t belong to muscle fibres is :

A
conductivity

B
Excitability

C
Contractility

D
elasticity

Solution

Muscle fibres have properties of excitability, elasticity and contractility but conductivity is not present in muscles fibers. These fibres help in movement of different body parts.
Question 3
1 / -0

A
Pubis

B
tibia

C
Ilium

D
Ischium

Solution

Hip bone or pelvic girdle consists of two coxal bones. Each coxal bone is formed by the fusion of three bones- ilium, ischium and pubis
Question 4
1 / -0

Aging will be characterised by :

A
decreased muscle size

B
decreased muscle size and increased muscle fat.

C
increased muscle fat

D
increased muscle protein

Solution

Aging will be characterized by decreased muscle size and increased muscle fat. With aging muscle loose its contractile and elasticity nature. Fats are deposited in muscle fibres the further decrease contracting ability.

Each coxal bone is formed by the fusion of three bones – ilium, ischium and pubis.
Question 7
1 / -0

Muscular dystrophy is a genetic disorder. MD :

i. It is genetically inherited.
ii. Some people get affected by MD due to mutated dystrophin gene and nutritional defects at the pre-natal age.
iii. Predominantly males are affected by DMD although females can be carriers of it.
iv. Dystrophin is a protein found in tendons.

A
all are correct.

B
onlyi) is correct.

C
onlyi) and iii) are correct.

D
only i),ii) and iii) are correct.

Solution

Muscular dystrophy is a genetic disorder and genetically inherited. It may also occurs due to mutated dystrophin gene and nutritional defects at the pre-netal age. Males are more affected by MD although females can be carriers of it.

A

B

C

D
none

Solution

Each ‘F’ actin is a polymer of monomeric ‘G’ (Globular) actins.

C
a)-iv, b)-ii, c)-i, d)-iii

D
a)-i, b)-iii, c)-iv, d)-ii

Solution

Different kinds of skeleton system is found in different organisms. Sphyma contain cartilaginous skeleton. Pediculus contain exoskeleton. Asterias contain endoskeleton and Metridium contains hydrostatic skeleton.
Question 10

Read the following about joint replacement therapy :

i. Artificial joints are made from the similar material that makes our bones.
ii. Metal or plastic is used to prepare an artificial joint.
iii. Following figure shows a disfunctional joint in the knee.
iv. Above figure shows an artificial joint in the knee.

A
only statement ii) and iv) are correct.

B
only statement i) and iv) are correct.

C
only statement i) and iii) are correct.

D
only statement iv) is correct.

Solution

Artificial joints are made up of metal and plastic. The figure shown above shows artificial joint in the knee.
Question 11
1 / -0

Look at the following figure of myofibrils
figure (1), (2), (3), (4) : showing ?

A
(1) & (2) represent relaxed state while (3) & (4) represent cross bridge formation

B
(1) & (2) represent relaxed state while (3) & (4) represent breaking of cross bridge

C
(1) & (2) represent contracted state while (3) & (4) represent breaking of cross bridge

D
(1) & (2) represent contracted state while (3) & (4) represent cross bridge formation

Solution

Myofibrils are present in muscles fibers which are parallelly arranged filaments in sarcoplasm. Figure 1 and 2 present relaxed state while figure 3 and 4 represents cross bridge formation.
Question 12
1 / -0

The upright posture in humans is facilitated by :

A
massive hindlimb bones making broad feet

B
only pelvis

C
radius and ulna

D
massive hind limb bones making broad feet and pelvis

Solution

The upright posture in human is facilitated by massive hind limbs bones that makes broad feet and pelvis to withhold the weight of whole body.
Question 13
1 / -0

Sachin suffers from hypoparathyroidism. This can lead him to :

A
hypoglycemia and tetany

B
hypoglycemia and arthritis

C
hypocalcemia and tetany

D
hypercalcemia and tetany

Solution

Hypoparathryrodism is the condition in which body secretes abnormally low level of parathyroid hormone. This deficiency may lead to hypocalcemia and tatany.

Question 15
1 / -0

Each pectoral girdle :

i. has 2 pairs of bones, a pair of clavicle and a pair of scapula.

both are wrong

D
Statement i) is correct and ii) is wrong.

Solution

The dorsal, flat, triangular body of scapula has a slightly elevated ridge called the spine which projects as a flat, expanded process called the acromion. Below the acromion is a depression called the glenoid cavity which articulates with the head of the humerus to form the shoulder joint.
Question 16
1 / -0

Which disorder is caused due to wild contractions in muscles?

Tetany is caused due to rapid spasms (wild contractions) in muscle due to low Ca++ inbody fluid.
Question 17
1 / -0

Read the following statements about muscle contraction in humans :
i. chemical energy is converted into mechanical energy during muscle contraction and the chemical is a neurotransmitter.
ii. a neurotransmitter acetylcholine at motor end plate converts electrical energy into mechanical energy.
iii. in a contracted muscle, volume remains the same.
iv. a contracted muscle becomes shorter and thicker.

A
only iv) is correct.

B
only i), iii) and iv) are correct.

C
only i) and iv) are correct.

D
only ii), iii) and iv) are correct.

Solution

The chemical energy is converted into mechanical energy during muscle contraction and the chemical is a neurotransmitter. In a contracted muscle, volume remains the same and a contracted muscle becomes shorter and thicker.

C
a)-iv, b)-ii, c)-iii, d)-i

D
a)-v, b)-ii, c)-iii, d)-iv

Solution

Hip bone is called as innominate bone, kneebone is called as patella, collarbone is called as clavicle and immovable joint is called suture.
Question 19
1 / -0

During vigorous exercise :

i. lactic acid accumulates in muscle cells to meet its energy needs immediately.
ii. lactic acid is formed by anaerobic respiration hence oxygen consumption by muscles is reduced.
iii. This reduction in oxygen consumption is called oxygen debt of muscle.

A
only statement ii) and iii) are correct.

B
only statement i) is correct.

C
only statement i) and ii) are correct.

D
all statements are correct.

Solution

During vigorous exercise, lactic acid accumulates in muscles cells to meet the energy requirement of muscle cell. Lactic acid is formed due to insufficient availability of oxygen.

neuromuscular disease

B
causing paralysis of respiratory muscles
