Gross anatomy (worth double points)
Located in the upper arm, this muscle with a two-headed name is famous for “flexing” to show off strength.
What is the biceps brachii?
These basic cellular building blocks of muscles are so long and thin that they are simply called fibers, and the type of these we have learned from has three types of it, this is a bonus type.
What are muscle cells?
This vital hardworking type of muscle tissue is found exclusively in the heart.
What is cardiac muscle?
Bending your elbow or making a fist is an example of this movement that decreases the angle between bones.
What is flexion?
Commonly called a "pulled muscle," this injury happens when muscle fibers are overstretched or torn.
What is strain?
This large, triangular muscle covers the lower back and sides, often called the “lat” for short.
What is the latissimus dorsi?
This abundant mineral is stored in the sarcoplasmic reticulum and released to trigger muscle contractions, and is the main substance for hair and nails.
What is calcium?
As its name suggests, this type of muscle connects to your bones and allows you to move your limbs.
What is skeletal muscle?
The exact opposite of flexion, this movement involves straightening out a joint, like unbending your knee.
What is extension
This is a sudden, painful, and involuntary tightening of a muscle, often happening in the calf during sleep or heavy exercise.
What is a cramp?
Named for its four distinct heads, this massive muscle group on the front of the thigh extends the knee.
In the sliding filament theory, this ”thin” protein filament slides past the thicker myosin filament.
What is atcin?
Becuase you have to think to consciously think to move them, skeletal muscles are classified as this type of muscle.
What are voluntary muscles?
Doing this to your muscles before or after a workout helps prevent injury, increases flexibility, and elongates the tissue.
What is stretching?
This well-known genetic disorder causes progressive weakness and a gradual loss of muscle mass over time.
What is muscualar dystrophy?
The longest muscle in the human body, it runs obliquely down the thigh and is named after the latin word for “tailor”.
What is the sartorius.
This energy-carraying nucleotide-carrying nucleotide provides the nesseccary fuel for myosin heads to bind and pull actin fillaments.
What is ATP(adenosine triphosphate)
Unlike skeletal muscles, cardiac and smooth muscles work automatically without you thinking, making them this type.
What are involuntary muscles?
Turning your head from side to side to signal "no" is an example of this type of movement around an axis.
What is rotation?
Fitness buffs know DOMS stands for Delayed Onset Muscle This, which sets in a day or two after a brutal workout.
What is soreness
This deep muscle of the calf, named after the type of flatfish, lies just beneath the gastrocnemius.
What is the soleus?
This protein blocks the myosin-binding sites on the atcin filaments when a muscle is at rest.
What is tropomyosin?
This type of involuntary muscle gets its name because it lacks the "stripes" seen in skeletal muscle; it lines your stomach and intestines.
What is smooth muscle?
Muscles work in pairs; while your biceps contracts to bend your arm, this muscle on the back of your arm must relax.
What is triceps?
If a broken leg is kept in a cast for weeks, the muscles will experience this 7-letter process, meaning they waste away from lack of use.
What is atrophy?
