Cardiac muscle is a tissue. It is made up of multiple cells working together.
Cardiac muscle is a tissue. It's a group of cells working together for a common function.
I think that would be the electrolytes.
Atomic Level: Oxygen atom Molecular Level: DNA Organelle Level: Cell Nucleus Cellular Level: Cardiac Muscular Cell Tissue Level: Cardiac Muscle Tissue Organ Level: Heart Organ System Level: circulatory system Organism Level: Zebra
The levels of organization in the human body in descending order are: organism level (whole human body), organ systems level (such as the cardiovascular system), organ level (heart), tissue level (cardiac muscle tissue), cellular level (cardiac muscle cell), and molecular level (molecules within the cell).
Cardiac muscle has what is called "autorhymicity", if it is not stimulated by a higher level brain center, it will stimulate itself. Ayraayra: The correct term is acutally automaticity.
cpk enzymes are found in cardiac muscle, skeletal muscle and the brain, cpk will be elevated 10 to 25 times the normal level following a myocardial infarction, they will also be elevated after a trauma to skeletal muscle and in progressive muscular dystrophy, cpk can be elevated after strenuous exercise.
The heart essentially is a muscle. Myocardium or cardiac muscle forms the majority of the heart and its chambers. It is It is an involuntary muscle, that is opperates on an automatic/unconcious level. It differs by several characteristics from smooth muscle (found in places such as the intestinal tract, stomach etc) and skeletial muscle (the muscle's you can EASILY see on body builders).
Skeletal muscles are designed to give maximum strength - the drawback to this is that they can only operate for a short while. Try holding your arm out straight level for an hour. Cardiac muscles are designed to work continuously (short bursts but forever) - the drawback to this is that their maximum effort is only mediocre. Skeletal muscles are attached to your bones,smooth muscles work in your organs,and cardiac muscles work in your heart.
The answer to your homework-assignment is:3 types of muscle-tissue occurs in the human body:Smooth muscle (not discussed in this answer)Skeletal muscleCardiac muscleCardiac and skeletal muscle will look more or less the same seen through the lens of a microscope, because they are both striated. However, there are small differences which we wont get into here. Physiologically as well as anatomically (at cell level) there are several other important differences.The most obvious reason however is this: While you can move skeletal muscle voluntarily, i.e. clenching your fist or flexing your biceps, you cannot voluntarily move cardiac muscle. It is self-governing and under higher control from the central nervous system.And the type of muscle used in the heart - yes you guessed it - Cardiac Muscle.
The lowest level of current that can cause serious injury is around 20 milliamperes (mA). Currents above this level can cause muscle contractions, difficulty breathing, and potentially lead to cardiac arrest.
