DISORDERS
100
Longest muscle in the body.
What is the sartorius muscle?
100
Individual parallel muscle fibers.
What are myofibrils?
100
The outermost layer of the muscle.
What is the epimysium?
100
The muscle fiber plus the motor neuron.
What is a motor unit?
100
A disorder in which muscles weaken over time, resulting in the inability to walk, talk, or breathe.
What is muscular dystrophy? 
200
the name of the muscles inside the heart.
What are cardiac muscles?
200
Transport.
What does the sarcoplasmic reticulum do?
200
Where the bundles of muscle fibers are stored. Also separates and surrounds fascicles.
What is the perimysium?
200
The sustained contraction of individual fibers, even when muscle is at rest.
What is muscle tone?
200
A disorder in which the joints of the body stiffen and become locked in place.
What is rigor mortis?
300
the muscle located on the lower back.

What is the latissimus dorsi?

300
inner material surrounding fibers (cytoplasm).
What is sarcoplasm?
300
Surrounds each muscle fiber.
What is the endomysium?
300
When fibers do not contract partially, they either do or don't.
What is the All-or-None Response?
300
A disorder in which there is a delayed relaxation of the skeletal muscles after voluntary contraction.
What is myotonia?
400
The main muscle on the chest.
What is the pectoralis major?
400
What myofibrils are made of.
What are actin and myosin?
400
The innermost layer of the muscle, deeper than the endomysium.
What are muscle fibers?
400
When muscles enlarge (either working out or certain disorders).
What is hypertrophy?
400
AKA amyotrophic lateral sclerosis.
What is ALS?
500
The function of the rectus femoris.

What helps extend the knee and flex the hip?

500
Muscle fiber membrane.
What is sarcolemma?
500
Surrounds the entire muscle.
What is the epimysium?
500
When more and more fibers contract as the intensity of the stimulus increases.
What is recruitment?
500
This disorder means "grave muscular weakness"
What is Myasthenia Gravis?
