Select the correct statement regarding the specific disorder of muscular of skeletal system.A Myasthenia gravis – Autoimmune disorder which inhibits sliding of myosin filaments B Gout – inflammation of joints due the extra deposition of calcium C Muscular dystrophy – Age related activation of muscles D Osteoporosis – Decrease in bone mass and higher chances of fractures with advancing age.

The correct statement regarding the specific disorder of muscular of skeletal system is D. Osteoporosis – Decrease in bone mass and higher chances of fractures with advancing age.

This is because osteoporosis is indeed characterized by a decrease in bone mass and density, leading to an increased risk of fractures. The other options are incorrect because:

A. Myasthenia gravis is an autoimmune disorder, but it does not inhibit the sliding of myosin filaments. Instead, it affects the communication between nerves and muscles, leading to weakness in the skeletal muscles.

B. Gout is an inflammatory condition, but it is not caused by the extra deposition of calcium. It is caused by the deposition of uric acid crystals in the joints.

C. Muscular dystrophy is not age-related activation of muscles. It is a group of genetic diseases that cause progressive weakness and loss of muscle mass.
