Answer 1

Question 1.

Answer:Myosin filaments also called thick filaments.

Myosin is a special protein that transforms adenosine triphosphate ( ATP), a molecule used by cells for living and working purposes, into mechanical energy.

Question 2.

Answer: This inherited degenerative disease of the muscular system is where the muscles weaken and atrophy and become replaced with fatty tissue.is a muscular dystrophy.

A group of genetic disorders that cause progressive flaws and loss of muscle strength.
Abnormal genes mutations lead to muscle degeneration in muscular dystrophies. Most forms start in childhood.

Question 3

Answer:This chronic, non-progressive condition of pain in the muscles, tendons, and ligaments is called Fibromyalgia

Wide-spread muscle pain and tenderness in muscles.
Fibromyalgia is also followed by tiredness and impaired sleep, memory, and mood.

Question 4

Answer:Blood is pumped through the heart by which type of muscle?

Its a cardiac muscle.cardiac smooth muscles which pump the blood through the heart.

Question 5

Answer:What is an example of a repetitive motion disorder?carpal tunnel syndrome.

Repetitive motion disorders (RMDs) are a family of muscular conditions that result from repeated movements during normal work or day-to-day activities.

Question 6.

Answer: Which of the following statements is not true?

Select one:

c. Growth of muscles in preschool years is relatively fast compared to the growth of infants and teens.
