  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

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

  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

  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'.

Which of the following is correctly matched?

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

  1. Relaxin- Gigantism

  2. Prolactin- Cretinism

  3. Parathyroid hormone- Tetany

  4. Insulin- Diabetes insipidus

Show answer
Correct Option: C
Explanation:

The correct combination of disease due to hyposecretion of these hormones:-

 Relaxin  Cervical dystocia
 Prolactin   Sheehan syndrome
 Parathyroid hormone  Tetany
 Insulin  Diabetes Mellitus

Tetany is related with parathyroid hormone or parathormone, it is responsible for calcium metabolism, the hyposecretion of parathormone lowers the blood calcium that results in the increasing the excitability of nerves and muscles.

Hypocalcemia (decreased $Ca^{+2}$ level of plasma) can lead to ______________.

  1. Tetany

  2. Renal calculi

  3. Osteoporosis
