Which one of the following diseases is caused due to immunological disorder against an unknown antigen?

disorders of muscular system disorders of muscle and skeleton movement and locomotion in man locomotion and movements biology

  1. Stroke

  2. Tuberculosis

  3. Rheumatic arthritis

  4. Multiple sclerosis

Show answer
Correct Option: C
Explanation:

  • Rheumatic arthritis is an example of an autoimmune disease that affects the joints.
  • The autoimmune diseases are generated due to the activity of the immune cells against the self-cells. 
  • The immune cells are not able to distinguish between the self and the non-self cells. 
  • There is no known antigen that can provoke the immune cells to show an immune response against the cells of the body. 
Thus, the correct answer is option C. 

Gout is a

  1. Deficiency disease

  2. Infectious disease

  3. Degenerative disease

  4. None of the above

Show answer
Correct Option: D
Explanation:

Gout is a clinical condition. Gout is a kind of arthritis. It can cause an attack of sudden burning pain, stiffness and swelling in a joint, usually a big toe. These attacks can happen over and over unless gout is treated. Over time, they can harm your joints, tendons and other tissues. Gout is most common in men. Gout is caused by too much uric acid in the blood. Most of the time, having too much uric acid isn't harmful. Many people with high levels in their blood never get gout. But when uric acid levels in your blood are too high, the uric acid may form hard crystals in your joints. It's not a degenerative disease, infectious disease and deficiency disease. Thus, option D is correct.

Still disease is a type of

disorders of muscular system disorders of muscle and skeleton movement and locomotion in man locomotion and movements biology

  1. Arthritis

  2. Rickets

  3. Sprain

  4. Osteoporosis

Show answer
Correct Option: A
Explanation:

Still's disease is an inflammation of joints causing arthritis which produces symptoms such as fever, rash, and joint pains. If it is not treated, the inflammation may destroy joints particularly the wrist joints. Steroids are used in treating this rare disease.

So, the correct answer is 'Arthritis'

Read the given statements and select the correct option.
Statement 1 : Inflammation of a skeletal joint may immobilise the movements of the joint.
Statement 2 : This is caused due to uric acid crystals in the joint cavity and ossification of articular cartilage.

  1. Both statements 1 and 2 are correct.

  2. Statement 1 is correct but statement 2 is incorrect.

  3. Statement 1 is incorrect but statement 2 is correct.

  4. Both statements 1 and 2 are incorrect

Show answer
Correct Option: A
Explanation:

Both statements 1 & 2 are correct with respect to the skeletal joint.

So, the correct option is 'Both statements 1 and 2 are correct.'

Inflammation of synovial membrane produces

disorders of muscular system disorders of muscle and skeleton movement and locomotion in man locomotion and movements biology

  1. Gout

  2. Rheumatoid arthritis

  3. Dislocation

  4. Osteoarthritis

Show answer
Correct Option: B
Explanation:
Rheumatoid Arthritis is an autoimmune disease that particularly affects the synovial membrane of joints leading to excessive production of synovial fluid thereby stretching the joint capsule causing joint pains.
Osteoarthritis is an inflammation and damage of the articular cartilages of joints causing joint pains. It does not primarily affect the synovial membrane.
Gout or Hyperuricaemia is an excessive amount of uric acid in blood leading to the accumulation of urate crystals in the joints causing joint pains.
Dislocation of the joint is a condition where the bone slips out of the joint due to an injury.

So, the correct answer is 'Rheumatoid arthritis'.

Gout that leads to arthritis is associated with abnormality of

disorders of muscular system disorders of muscle and skeleton movement and locomotion in man locomotion and movements biology

  1. Pyrimidine metabolism

  2. Purine metabolism

  3. Fat metabolism

  4. Protein metabolism

Show answer
Correct Option: B
Explanation:
Gout or Hyperuricaemia is a condition of increased uric acid in the blood. Uric acid is the end product of purine(Adenine, Guanine) metabolism in the body.
Any abnormality in the uric acid metabolism can lead to overproduction of uric acid and excessive uric acid in the blood can lead to accumulation of urate crystals in joints causing inflammation of joints/arthritis.
So, the correct answer is 'Purine metabolism'

Which of the following is due to irregularity in metabolism of nitrogenous waste?

disorders of muscular system disorders of muscle and skeleton movement and locomotion in man locomotion and movements biology

  1. Osteoarthritis

  2. Rheumatoid arthritis

  3. Osteoporosis

  4. Gouty arthritis

Show answer
Correct Option: D
Explanation:

Gouty arthritis is an inherited disorder of purine metabolism, occurring especially in men, gout is related to diet that giving rise to severe arthritis called gouty arthritis, a person suffering from gout should avoid meat. Purine is a nitrogenous waste.

So the correct answer is 'Gouty arthritis'.

Choose the correct answers from the alternatives given.
When out of oxygen, vertebrate muscle:

biology movement and locomotion in man types of muscles muscles muscles and their structure muscle contraction

  1. produces lactic acid

  2. produces more carbon dioxide

  3. stops functioning

  4. degrades protein

Show answer
Correct Option: A
Explanation:
The repeated contraction of the muscle results in the low concentration of oxygen and this anaerobic condition leads to the accumulation of lactic acid in the muscle. 
So, the correct option is 'produces lactic acid'

Extensor muscles of back have

biology movement and locomotion in man types of muscles muscles muscles and their structure muscle contraction

  1. An aerobic oxidation

  2. Fast rate of contraction

  3. Larger diameter muscle fibers

  4. Abundant in myoglobin

Show answer
Correct Option: A,D
Explanation:

Extensor muscles. Attached to the back of the spine, these muscles allow us to stand and lift objects. They include the large muscles in the lower back (erector spinae), which help hold up the spine, and gluteal muscles.

Extensor muscles are one of the examples for red muscles which contains abundant mitochondria and myoglobin. 
Red muscle fibres contract and fatigue more slowly than white fibres and generate ATP by aerobic catabolism of glucose and fats, utilizing myoglobin-bound O2
Myoglobin is abundant and great numbers of mitochondria occur, characterized by slow, sustained (tonic) contraction.
So, the correct answer is 'An aerobic oxidation and Abundant in myoglobin'

Smallest muscle in the human body

biology movement and locomotion in man types of muscles muscles muscles and their structure muscle contraction

  1. Sartorius

  2. Spinal muscle

  3. Stapes

  4. Stapedius

Show answer
Correct Option: D
Explanation:

The stapedius muscle, which is innervated by the facial nerve (cranial nerve VII), is the smallest of all skeletal muscles.
