How would you distinguish the structure of cardiac muscle from the structure of skeletal muscle?

one is slippery-which is the cardiac muscle\n\nanoter one is rough- which is the skeleton muscle.

THe heart is made up of two pumps; one that contains oxygenated blood, and one that contains deoxygenated blood...they are divided by this thick wall called a septum...each half is made up of a ventricle and an atrium...that question was on my science quiz today!!!

anatomy is all memorization of bones, muscles, artries veins, tissues and so one\nand physiology is more complex is the function of  how our systems work and whats an action potential physio is more diffucult than anatomy

As the heart increase in size, the surface area increase by the square, while the internal volume increases by the cube.\nExample: internal volume = Length * Width * height\n\nAs the internal volume increases the amount of blood pumped per heart beat (stroke volume) increases.\n\nThe actual “strength” of the heart is unchanged. Cardiac myosites are essentially unchanged between different mammal species. \n\nWell trained athletes tend to have a health heart hypertrophy (enlarged heart) and have heart beats in the 40’s-50’s BPM while the average adults range in the 60’s-80’s.\n\nAs an end product of all of this, large animals tend to have slower metabolic rates because while it may be possible for a 6 oz bird to eat its weight in insects a day a large animal like a dog can not be expected to do so.

Isn't this something they're trying to teach you at school? Think of the origins and insertions of these muscles, and of the movements achieved when each muscle layer contracts. Look at the pictures in any good Comparative Anatomy book and check the difference between the muscles of fishes and tetrapods (hint: new feature- lungs).

Type IIB and type IIX are different subtypes of skeletal muscle. They are not the same thing.

4 chambers ...\nWithin the adult heart are two parallel independent systems, each consisting of an auricle, or atrium, and a ventricle; from their anatomical positions these systems are often designated the right heart and the left heart.

There are three different kinds of muscle, and each does a different kind of work:\n\nSmooth muscle, also known as involuntary muscle, is found in the digestive tract, the urinary system, the blood vessels, and the reproductive organs.  (Yes, you need it to have sex.  Treat your smooth muscle well.)  It's non-stratiated, meaning that it's not very organized compared to other muscle.\n\nCardiac muscle is also a type of involuntary muscle.  It is found only in the heart.  In structure, it is a sort of middle ground between smooth muscle and skeletal muscle.\n\nSkeletal muscle, or voluntary muscle, is anchored to bones and tendons and used for movement.  It is very well organized.

(1)Heart is  the hollow muscular organ that receives blood from the veins and propels it into and through the arteries.\n(2)It helps to bring blood from the body returns to the right atrium through two large veins, the superior and inferior venae cavae; in addition the blood that has supplied the heart muscle is drained directly into the right atrium through the coronary sinus.

I found this great website http://www.yourpracticeonline.com.au/showcase.html\n\nIf you scroll right down to the bottom of the page there is a table in white, with a column labelled Heart, then under that click on the Heart Anatomy link. Sorry can't send you direct link - but this opens up a window with a superb anamation you can click around and even move around a 3d model of the heart. Then if you go through the presenation all the main items of the heart are shown.

Animal muscle tissue is fascinating, when you learn how it works or "clenches". The process by which muscle clenche and release seems rather complicated to learn about.  But, it's worth it.  I believe there's a possibility for alternative energy stemming from the principles for how muscles work.  I wish all engineers had to learn about anatomy and physiology.  Here are the three easiest sites I could find. You might buy a used entry level human anatomy and physiology textbook and just start at the beginning, don't try to remember all the names of everything.  But start with cells and move up to muscle tissue early in the text. It's amazing stuff. Excellent question and sense of curiosity:\n\n\nhttp://en.wikipedia.org/wiki/Muscle_contraction\nhttp://users.rcn.com/jkimball.ma.ultranet/BiologyPages/M/Muscles.html

muscle tissue cells- smooth (ability to contract) and cardiac(heart)\nepithelial tissue cells- forms the skin and organs

Lung tissue looks like a sponge.  Heart tissue looks like a steak.  Do an image search.

blood is necessary to sustain all muscles within the body.  The heart is a big muscle.  Muscle needs oxygen in order to survive.  Without a proper blood supply, it will eventually die.

organelle is a microscopic component of a cell...whereas a structure is refered to a cell..a whole cell and it's components

The contraction of a skeletal muscle is caused by the movement of actin and myosin fibers resulting from influx of exracelluar calcium caused by surface depolarization of the cell initiated by presynaptic discharge of a motor neuron. If this is a homework question, I suppose a one word answer would depend on the nature of the course discussion to which this question is addressed.
