Question

which of the following types of muscle tissue does not experience fatigue

skeletal muscle

none of the above

smooth muscle

cardiac muscle

Explanation:

• Skeletal muscle: It is voluntary muscle. It can experience fatigue due to intense or prolonged use. For example, after a long - distance run, skeletal muscles in legs get fatigued.
• Smooth muscle: It is found in internal organs like the digestive tract. It can also experience fatigue. For instance, in certain digestive disorders where smooth muscle contractions are over - exerted, fatigue can occur.
• Cardiac muscle: It has a high resistance to fatigue. This is because it has a rich blood supply (coronary circulation) to provide a continuous supply of oxygen and nutrients. Also, it has a large number of mitochondria (the powerhouses of the cell) to generate ATP (adenosine triphosphate, the energy currency) continuously.

Answer:

Cardiac muscle
