  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? 

zoology locomotion and movement disorders of musculoskeletal system disorders of muscle and skeleton joints and movements

  1. Osteoporosis

  2. Arthritis

  3. Diabetes

  4. Both (B) and (A)

Show answer
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

Show answer
Correct Option: D

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

zoology locomotion and movement disorders of musculoskeletal system disorders of muscle and skeleton joints and movements

  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

Show answer
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

Show answer
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

zoology locomotion and movement disorders of musculoskeletal system disorders of muscle and skeleton joints and movements

  1. Biological agent

  2. Mechanical agent

  3. Physical agent

  4. Chemical agent

Show answer
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 

zoology locomotion and movement disorders of musculoskeletal system disorders of muscle and skeleton joints and movements

  1. Sprain

  2. Dislocation

  3. Fracture

  4. Tension

Show answer
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'.

Select the correct statement about muscular disorder.

zoology locomotion and movement disorders of musculoskeletal system disorders of muscle and skeleton joints and movements

  1. Accumulation of urea and creatine in joints

  2. An overdose of vitamin D causes osteoporosis

  3. Rapid contraction of skeletal muscles causes dystrophy

  4. Failure of neuromuscular transmission in myasthenia gravis can prevent normal swallowing

Show answer
Correct Option: D
Explanation:
  • Autoimmune diseases are a group of disorders in which tissue injury is caused by humoral (autoantibodies) or cell-mediated (by autoreactive T cells) immune response to self-antigens.
  • Myasthenia gravis is caused by an autoantibody against muscle antigen and acetylcholine receptor antigen.
  • It is characterized by increased muscular weakness the make one fatigue. speaking, breathing and talking becomes tired some. The failure of neuromuscular transmission in myasthenia gravis can prevent normal swallowing.
  • So, the correct answer is 'Failure of neuromuscular transmission in myasthenia gravis can prevent normal swallowing'.
