People who have had a stroke tend to experience muscle wasting which is called ...... and is caused by.....

• Hypertrophy, muscles are rarely moved

• Atrophy, the brain is unable to regulate the muscles

• Atrophy, muscles are rarely used

• Hypertrophy, lack of muscle nutrition

• Hypertrophy, muscle is actively contracting

The mechanism that occurs in muscle contraction is....

• Lengthening of muscle size due to friction of actin and myosin molecules that require energy from the breakdown of ATP

• Lengthening of muscle size due to friction of myofibrils that require energy from aerobic metabolism of glucose

• Relaxing muscle size due to myofibril shear which requires inorganic calcium and phosphate ions

• Shifting of thicker filaments to thinner filaments and energy required from the breakdown of pyruvic acid

• Shortening of muscle size due to the Z zone becoming longer and the H zone becoming shorter, which requires energy from the breakdown of ATP
