Which of the following endocrine gland is associated with tetanus?

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

  1. Islets of Langerhans

  2. Thyroid gland

  3. Parathyroid gland

  4. Adrenal gland

Show answer
Correct Option: C
Explanation:

Symptoms of tetanus include
 a)Tetanus often begins with mild spasms in the jaw muscles known as lockjaw. The spasms can also affect the facial muscles and experience spasms and stiffness in various muscles, especially those in jaw, abdomen, chest, back, and neck.
b)Muscle cramps or spasms in your legs, fever, high blood pressure etc
Hypoparathyroidism is decreased function of the parathyroid glands with underproduction of parathyroid hormone. This can lead to low levels of calcium in the blood, often causing cramping and twitching of muscles or tetany (involuntary muscle contraction).
Hence parathyroid gland is associated with tetanus.
So, the correct answer is 'Parathyroid gland'.

Myasthenia gravis is an example of

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

  1. Viral disease

  2. Immunological disease

  3. Autoimmune disease

  4. Allergic reactions

Show answer
Correct Option: C
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.
  • Myasthenia gravis is characterized by increased muscular weakness the make one fatigue. speaking, breathing and talking becomes tired some. Hence myasthenia gravis is an example of autoimmune disease.
  • So, the correct answer is 'Autoimmune disease'.

Progressive degeneration of skeletal muscle, mostly due to genetic disorder occurs in

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

  1. Myasthenia gravis

  2. Muscular dystrophy

  3. Arthritis

  4. Tetany

  5. Osteoporosis

Show answer
Correct Option: B
Explanation:
  • Muscular dystrophy is a group of inherited muscle diseases in which muscle fibers are unusually susceptible to damage.
  • It is characterized by progressive skeletal muscle degeneration, defects in muscle proteins and the death of muscle cell and tissue.
  • Hence progressive degeneration of skeletal muscle, mostly due to genetic disorder occurs in muscular dystrophy.
  • So, the correct answer is 'Muscular dystrophy'.
