The over-stretching of tendons and ligaments is called as

  1. Tonus

  2. Tetany

  3. Sprain

  4. Fatigue


Correct Option: C
Explanation:

A sprain is an injury to the ligaments around a joint. Ligaments are strong, flexible fibers that hold bones together. When a ligament is stretched too far or tears, the joint will become painful and stress.
Tonus is the slight, continuous contraction of a muscle.
Tetany consists of the involuntary contraction of muscles.
Fatigue is the general overall feeling of tiredness and lack of energy.
So, the correct answer is option C.

Gout is caused due to accumulation of?

  1. Oxalic acid

  2. Uric acid

  3. Calcium carbonate

  4. Lactic acid


Correct Option: A

Which of  the following pair is incorrect in relation to diseases and related symptoms-

  1. Rheumatoid arthritis-accumulation of pannus granules

  2. Rickets-Incomplete and insufficient deposition of calcium and phosphate into bones

  3. Gouty Arthritis- Deposition of urea into joints

  4. Osteoporosis- Deficiency of vitamin D


Correct Option: A

Deposition of ______ in the joints causes gout.

  1. Urea

  2. Uric acid

  3. Guanine

  4. Ammonia


Correct Option: B

Which of the following are skeletal disorders? 

  1. Osteoporosis

  2. Arthritis

  3. Diabetes

  4. Both (B) and (A)


Correct Option: D
Explanation:

Arthritis is a disorder of the joints. It involves inflammation of one or more joints. When affected by arthritis, the joint or joints affected may be painful to move, may move in unusual directions or may be immobile completely. Osteoporosis is a disease of bone where there is reduced bone mineral density, increasing the likelihood of fractures. 

So, the correct answer is 'Both (B) and (A)'.

Osteomalacia is a deficiency disease of

  1. Infants due to protein energy malnutrition

  2. Adults due to protein energy malnutrition

  3. Infants due to vitamin D/Calcium deficiency

  4. Adults due to vitamin D/Calcium/ Phosphorus deficiency


Correct Option: D

Select the correct statement about disorder of muscular or skeletal system.

  1. Muscular dystrophy $\rightarrow$ Age related shortening of muscles

  2. Myasthenia gravis $\rightarrow$ Autoimmune disorder which inhibits sliding of myosin filaments

  3. Gout $\rightarrow$ Inflammation of joints due to extra deposition of calcium

  4. Osteoporosis $\rightarrow$ Decrease in bone mass and higher chances of fractures with advancing age


Correct Option: D
Explanation:
  • Skeletal system consists of a framework of bones and a few cartilages.
  • Osteoporosis is defined as a low bone mass and microarchitectural deterioration of bone tissue, leading to enhanced bone fragility and a consequent increase in fracture risk.
  • It occurs due to various fractures such as calcium deficiency, hyperparathyroidism, estrogen deficiency in females etc,
  • Hence osteoporosis →→ Decrease in bone mass and higher chances of fractures with advancing age.
  • So, the correct answer is 'Osteoporosis →→ Decrease in bone mass and higher chances of fractures with advancing age'.

In certain parts of India muscular distrophy is commonly found among the poor people because they eat cheap pulses of

  1. Phaseolus mungo

  2. Pisum sativum

  3. Lathyrus sativus

  4. Cicer


Correct Option: C
Explanation:

Lathyrus sativus also known as Kesari dal is mainly consumed by poor people. It causes paralysis because of the action of neurotoxin OAA present in it.

So the correct option is C.

Dislocation is a disease caused by

  1. Biological agent

  2. Mechanical agent

  3. Physical agent

  4. Chemical agent


Correct Option: B
Explanation:

Dislocation is a disease which occurs when there is an abnormal separation in the joint, where two or more bones meet. Most common sites of dislocation are shoulder, hip, patella, ankle and fingers. Dislocations are often caused by sudden trauma on the joint like an impact or fall. Mechanical agents are the major cause of dislocation, sprains, injuries, fractures etc.

So, the correct answer is 'Mechanical agent'.

At times ligaments and tendons are overstretched or torn. The phenomenon is 

  1. Sprain

  2. Dislocation

  3. Fracture

  4. Tension


Correct Option: A
Explanation:
  • The bands of fibrous tissue that connect bones to bones at joints are called as Ligaments and which connect muscles to the bones are called as tendons.
  • At times ligaments and tendons are overstretched or torn. The phenomenon is called a sprain.
  • Sprain happen most often in the ankle but can occur at any joint, such as the wrist or knee.”
  • So, the correct answer is a 'Sprain'.
