Angina is chest pain cause by reduced blood flow to the heart.
What muscle is used when shrugging your shoulders?
A number of muscles are involved in shrugging your shoulders, including the latissiumus dorsi, the deltoids, the rhomboids, the scapular muscles, the biceps, the triceps, among others. The primary muscle is the upper trapezius muscle. The secondary muscles are the middle trapezius muscles and the levator scapulae.
Why is voluntary muscle also called skeletal muscle?
They contract when stimulated by motor neurons of the Central Nervous System or CNS (Martini & Nath, 2009).

Voluntary muscles are ones that you have the ability to consciously control: Arms, legs, mouth, head movement, etc. Most of the major muscle groups used or movement and communication are voluntary.
Involuntary muscles would be things like your heart and the muscles around your intestines, which you generally cannot consciously control.
The skeletal is called "voluntary" muscle because it is usually subject to conscious control.
Voluntary muscles are muscles that move because you decide to cause them to move. You also have involuntary muscles that move on their own without your thinking about it, and usually you are not able to influence their movement much.

The loin area in Latin is termed lumb-, or lumbo. So any muscles that have one of those roots in their name are loin muscles. An example is the quadratus lumborum.
What is the muscles group that is located on the top half of the leg in the back?
the prosterby muscle is the answer
quadricepts are the muscle on the front of your leg above the knee. they are used in football, rugby etc
What does the cardiac muscle look like?
It depends on the type of muscle. We have three kinds, smooth, cardiac, and skeletal. The skeletal ones are called striated because they have bands that divide the smallest contracting units called sarcomeres. Skeletal muscles look much like long cords, cardiac are 'Y' or 'H' shaped, and smooth muscle are spindle shaped.
What kinds of muscle tissue have important circulatory functions?
Both Cardiac and Skeletal muscles help the circulatory system. The cardiac muscle is in the heart, which cycles the blood through the veins and arteries. Skeletal muscle helps push blood in distal blood vessels against gravity into the inferior vena cava and then the heart.
Which muscle acts to medially rotate the tibia?
I believe it is the semitendinosus, semimembranosus and popliteus muscles.
What muscles do you work out when you wash dishes?
You use your pectoral , biceps , triceps , forearm hamstring / thigh (same thing) and calf to keep you standing , shoulder muscles and abdominal

What is the fastest working muscle in the body?
The muscles know as Type IIx (also known as type IId), which is less dense in mitochondria and myoglobin. This is the fastest muscle type in humans. It can contract more quickly and with a greater amount of force than oxidative muscle, but can sustain only short, anaerobic bursts of activity before muscle contraction becomes painful (often incorrectly attributed to a build-up of lactic acid). N.B. in some books and articles this muscle in humans was, confusingly, called type IIB.
The muscle with the fastest reaction time is the muscles used to close your eyelids. These are very close to the brain which is one reason why they are so quick. The other reason is if an object is seen coming towards the eye, it will close to prevent severe damage from occurring. Sometimes you will not even notice your eyes closing and then you are hit by something.
What muscles are worked doing a reverse fly?
Primary: Posterior Deltoids
Secondary: Rhomboids and Traps
How do muscles work with bones to allow locomotion in humans?
Muscles do is to command the bones to move and you need food and energy to move around.
What role does ATP play in muscle contraction?
The role ATP plays in muscle contraction is that ATP binds to sites on myosin heads, inducing a conformational change in the actin binding site and reducing the affinity for the actin substrate. Hydrolysis of ATP then cocks the myosin head and moves it closer to the z disk. Release of ADP increases the affinity of the actin binding site and a power stroke moves the head roughly 100 angstroms closer to the z disk. In short, after the power stroke, ATP is hydrolyzed to release the myosin heads from actin so that they can go to the next binding site on the actin filament. It's sort of like reloading the myosin gun.
I believe you are asking about striated, not banded. Two types of muscle are striated, skeletal and cardiac muscle.
Spasms of this straplike muscle often result in wryneck or torticollis?
The sternocleidomastoid muscle in the neck. Injury also called a wry neck.
The Hamstring muscles flex the knee. There are 3 of them
Semimembranosus: is the most superficial (closest to the surface), found on the medial (inner) side of the back of the thigh.
Semitendonosus: is found underneath semimembranosus
Biceps Femoris: is found on the lateral (outer) side of the back of the thigh. Attaches to the fibula and outside of the tibia
What ten muscles do you use every day?
eat, drink, blink, talk, breath, turn your head, walk, run, type, and EVERYTHING ELSE.
