Because it`s made of muscle. Cardiac muscle. Involuntary striated myocytes.
The heart is made up of cardiac muscle, which is a type of striated muscle.
The heart is made of smooth and cardiac muscle
myocardium
The heart itself is a muscle, however the heart all is made up of different muscles. The muscle knows as the MYOCARDIUM makes up the largest portion of the Heart Wall. The myocardium is made up of the cardiac muscle tissue, which is responsible for the pumping action.
The tissue which makes up cardiac muscle has striations present. The heart, which is made up of special cardiac muscle is composed of lots of branching cells that join into a continuous mass by intercalated discs. Cardiac muscle is also known as striated involuntary muscle. This cardiac muscle tissue forms the bulk of the heart walls of each chamber. The striations in cardiac muscle are irregular, but they are present. Striated muscle is also found in skeltal muscle tissue, skeletal muscle tissue unlike cardiac muscle tissue has a regular striated structure which you can easily see through histolgy.
The thick muscle layer of the heart is the myocardium. It is the middle layer of the heart and produces pressure.
It's the heart
no..only skelet muscle.....
The muscle of your heart MUSCLE would be your heart.
The muscle layer of beef gullet meat tissue is made up of striated muscles and the tissue layer is composed of compact muscle bundles. The muscle fibres are tightly joined by endomysium. The protein content of the gullet meat tissue is similar to that found in less valuable sorts of meat.
smooth muscle cell tissue
