The heart is composed of cardiac muscle fibers. It is the same thing.

Yes, It does. :) Cardiac muscle have a nucleus, same as skeletal muscle and smooth muscle


Resting heart rate goes down (maximum stays the same).


Cardiac muscle is involuntary because its muscles related to the heart and if they were voluntary you would have to mentally tell your heart to pump each time. Smooth muscle tissue is involuntary because of the same reason as cardiac but instead it is located in areas such as hollow organs in the body, blood vessels,bladder, uterus,digestive tract.


No. The heart muscle contracts in sections, first the top (atrium) then the bottom (ventricle). But when it is working properly, the heart muscle fibers contract together in large groups.


No. Cardiac muscles are involuntary while skeletal muscles are voluntary, meaning you have control of the arm muscles, but not the heart muscles.


Muscle, just like the rest of the heart. edit: cardiac muscle is the tissue that makes up the heart so the right atrium is made up of the same tissue



which has more nuclei per cell skeletal muscle or cardiac muscle? I guess that they both have the same number of nuclei.


Cardiac Muscle it can be found in the heart it is called Involuntary because its contraction does not require conscious effort. It is also Striated in the same way as skeletal muscle.Hope I helped!!!


You call it as cardiac muscles. The muscle fibers contract rhythmically. The muscle fibers are attached to each other end to end. This facilitates the conduction of the impulse. The muscle fiber can be stimulated to give you contraction of the the same.


Cardiac distress is the same thing as a myocardial infarction, or heart attack.


Skeletal muscleBranchiomeric muscle (the same as skeletal muscle but different embryology)Cardiac muscle


Heart muscle is striated but not in the same way that skeletal muscle is. Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart.Cardiac and skeletal muscle are similar in that both appear to be striated in that they contain sarcomeres. In striated muscle, such as skeletal and cardiac muscle, the actin and myosin filaments each have a specific and constant length on the order of a few micrometers, far less than the length of the elongated muscle cell (a few millimeters in the case of human skeletal muscle cells).The filaments are organized into repeated subunits along the length. These subunits are called sarcomeres. The sarcomeres are what give skeletal and cardiac muscles their striated appearance of narrow dark and light bands, because of the parallel arrangement of the actin and myosin filaments.However, cardiac muscle has unique features relative to skeletal muscle. For one, the myocytes are much shorter and are narrower than the skeletal muscle cells, being about 0.1 millimeters long and 0.02 millimeters wide .Furthermore, while skeletal muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles.Anatomically, the muscle fibers are typically branched like a tree branch. In addition, cardiac muscle fibers connect to other cardiac muscle fibers through intercalcated discs and form the appearance of a syncytium (continuous cellular material).These intercalcated discs, which appear as irregularly-spaced dark bands between myocytes, are a unique and prominent feature of cardiac muscle .


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.


Cells that are the same form tissues. Muscle cells form muscle tissue.


the cardiac muscle is the heart. oxygenated blood flows into the heart, the heart pumps. this pushes the blood around the body transporting oxygen and collecting waste products such as carbon dioxide. deoxygenated blood is the same but is pumped to the lungs to be oxygenated. i hope that helps?


Involunary Musicle is only found in the heartreal answer...the cardiac tissue is found in your heart. it is involuntary and is striated.THe same in pigs but not goatsALL OF UR BASE R BELONG TO US



YesThe heart is a muscle tissue - cardiac to be preciseAny living piece of an organism is a tissueTissue is a cellular organizational level intermediate between cells and a complete organism. A tissue is an ensemble of similar cells and from the same origin, that together carry out a specific function.There are four main types of tissue:connectivemusclenervousepithelialThere are three types of muscle:smoothskeletalcardiac


They are the same thing. The only cardiac arrhythmia is asystole or no electrical activity in the heart. Cardiac arrest is the sudden cessation of the hearts functions.


Cardiac output will level off as your heart muscle strengthens and your body becomes accustomed to physical activity. For example, when first getting started, walking 5 minutes may be enough to increase your heart rate, but within a few weeks, you will need to increase the intensity of your walk to increase your heart rate by the same amount.


The heart is a organ-muscle that is about the same size of your fist.


There are two types of cardiac muscle cells, those that contract and those that set the rhythm. Both are basically the same cell.


Since the stroke volume increased then the cardiac out put would increase, pumping out more blood with the same amount of heart beats.


A cow's heart is a bit bigger than a human's heart, because of it's more massive body size. But other than that, the heart of a bovine is really the same as a human's, with four chambers and cardiac muscle that enables blood to be pumped through and from arteries and veins.
