Question 1 of 20

According to the National Institutes of Health, the category "muscular dystrophy" includes how many diseases?

more than 30

... More than 30 progressively degenerative muscular diseases are grouped together under the term "muscular dystrophy."


Question 2 of 20

The muscles affected by muscular dystrophy _________.

are only skeletal muscles
eventually include all muscles
surround the organs
vary depending upon the form of of muscular dystrophy

... For each person, the muscles affected depend upon the type of muscular dystrophy and the severity. All muscles could be compromised, or it might be limited to one area, such as the pelvis, shoulder or face.


Question 3 of 20

Treatment to cure muscular dystrophy _________.

does not exist
exists for only one form of it
exists for some forms of it
exists for all forms of it

... There is no current treatment that will cure or reverse muscular dystrophy. Treatments are designed to alleviate specific symptoms such as respiratory difficulties and seizures.


Question 4 of 20

Individuals with muscular dystrophy begin to show symptoms _______.

as infants
as young children
in adolescence
at various times

... Although the more serious forms of muscular dystrophy begin showing their symptoms in early childhood, it tends to vary -- onset can even become symptomatic at adulthood.


Question 5 of 20

Muscular dystrophy is caused by ___________.

a bacterium
genetic inheritance
an impaired immune system
a virus

... Muscular dystrophy is an inherited disease.


Question 6 of 20

According to the Mayo Clinic, much of the research into muscular dystrophy is focused on __________.

gene therapy
in vitro surgery
laser surgery

... Gene therapy is a significant area of muscular dystrophy research; the focus is stopping the development of the disease.


Question 7 of 20

Research into muscular dystrophy also includes ___________.

drug therapy to slow muscle loss
enhancement of the body's ability to repair muscles
stem cell research
all of the above

... Research into reducing muscle loss, repairing damaged muscles and using stem cells to introduce a missing protein are all ongoing efforts.


Question 8 of 20

Physical therapy is used by muscular dystrophy patients to ________.

maintain flexibility
clear lung secretions
control edema
manage wounds

... Tendons progressively retract in muscular dystrophy patients, and physical therapy can be utilized to help maintain range-of-motion.


Question 9 of 20

One drug treatment for muscular dystrophy is the use of corticosteroids to __________.

control seizures
delay muscular degeneration
fight infections
reinvigorate dying cells

... Corticosteroids are used to reduce the rate of muscle loss.


Question 10 of 20

Vaccinations for pneumonia and influenza are important for patients with muscular dystrophy because of __________.

lung nodules
mucus build-up in lungs
suppressed immune systems
weakened respiratory muscles

... Some forms of muscular dystrophy affect the respiratory muscles surrounding the lungs and can make it extremely difficult for patients to breathe.


Question 11 of 20

Researchers of two of the later-onset forms of muscular dystrophy, myotonic and facioscapulohumeral muscular dystrophy, are assisted by a national registry that shares information about _________.

certification processes
family histories
federal funding sources
all of the above

... The federally-funded registry collects family histories, recruits patients for research and stores medical data. It is housed at the University of Rochester in New York State.


Question 12 of 20

According to the Centers for Disease Control, the two most common forms of muscular dystrophy in children affect ________.

boys more than girls
girls more than boys
boys and girls at approximately equal rates

... Duchenne and Becker muscular dystrophy affect around 1 in 3,500-5,000 boys.


Question 13 of 20

As muscular dystrophy progresses into the later phases, muscle fiber may be replaced by ____________.

epithelial tissue
nerve cells

... In the most serious stages of muscular dystrophy, muscles are often supplanted by fat and connective tissue.


Question 14 of 20

In 2009, researchers discovered a significant gene difference between humans and _________, which had been used as laboratory animals to study muscular dystrophy.

great apes

... Rats and mice do not have two specific components of the Duchenne muscular dystrophy gene, which could have affected their bodies' responses to experiments. Lack of knowledge of this difference may have negatively impacted research up to that time.


Question 15 of 20

Developmental disabilities due to muscular dystrophy occur ________.

in all cases
in some cases
in most cases
in no cases

... Developmental disabilities may be present in people who have some forms of muscular dystrophy, but they are not always present.


Question 16 of 20

The most common form of muscular dystrophy is due to a lack of a/an ___________.

reuptake inhibitor

... People with Duchenne, the most common type of muscular dystrophy, lack the protein dystrophin.


Question 17 of 20

Parents can find out if a child in the womb has muscular dystrophy through ___________.

umbilical blood testing
There is no prenatal test for muscular dystrophy.

... Amniocentesis (at 14-16 weeks) or CVS (chorionic villus sampling) in early pregnancy can be used to test for the presence of muscular dystrophy.


Question 18 of 20

Muscular dystrophy patients often develop contractures, which are __________.

dead muscles
muscle spasms
shortened muscles
twitching muscles

... A contracture is the permanent shortening of a muscle. In patients with muscular dystrophy, joints such as hands, feet, knees and hips are often affected.


Question 19 of 20

Some of the research into Duchenne muscular dystrophy gene mutation focuses on the use of __________.

gene splicing
stem cell implants

... Researchers propose that 80 percent of Duchenne muscular dystrophy patients could be helped by gene splicing, which may avoid the mutation altogether.


Question 20 of 20

As a result of the Muscular Dystrophy Community Assistance, Research and Education Amendments Act of 2001, the National Institutes of Health established muscular dystrophy research centers named for __________.

President Gerald Ford
Senator Paul Wellstone
Senator Ted Kennedy
Vice President Walter Mondale

... The centers are named for Senator Paul Wellstone of Minnesota, who was killed in a plane crash in 2002. Senator Wellstone was a strong proponent of muscular dystrophy research.
