Muscular system diseases

Front

What is Myasthenia gravis?

Back

An autoimmune disease that attacks acetylcholine receptors, leading to muscle weakness.

Front

What causes muscle fatigue during anaerobic respiration?

Back

The build-up of lactic acid.

Front

What is muscle atrophy?

Back

The wasting away of muscle tissue.

Front

What is myotonic dystrophy?

Back

A condition where muscles contract but have decreasing power to relax, leading to weakness and wasting away, with symptoms becoming more severe with each generation.

Front

What is rigor mortis?

Back

A condition that occurs after death due to the lack of ATP, preventing the removal of myosin cross bridges.

Front

What is muscular dystrophy?

Back

A group of genetic diseases characterized by progressive weakness and degeneration of the skeletal muscles.

Front

What role does acetylcholine play in muscle contraction?

Back

Acetylcholine is a neurotransmitter that transmits signals from nerve cells to muscle cells, initiating muscle contraction.

Front

What is the difference between atrophy and hypertrophy?

Back

Atrophy is the decrease in muscle size and strength, while hypertrophy is the increase in muscle size due to exercise.

Front

What is lactic acidosis?

Back

A condition characterized by the build-up of lactic acid in the body, often due to intense exercise or oxygen deprivation.

Front

What is the significance of ATP in muscle function?

Back

ATP provides the energy required for muscle contractions and the relaxation of muscles.
