Cardiac Muscle Cells
Learn all about cardiac muscle cells!
Main Function
Cardiac Muscle Cells in Contraction
The Three Most Common Organelles in Cardiac Muscle Cells
Myofibrils- These surround the mitochondria and the glycogen. These organelles are so important because they take the energy produced by other organelles and use it to drive the contractions that allow blood to be pumped.
Glycogen- These are also surrounded by the myofibrils and their purpose is to store the energy. This is essential so that when energy is needed it is taken directly from the glycogen.
Connection- As you can see these 3 organelles create a chain of events. The mitochondria creates the energy(ATP), the glycogen stores the energy, and the myofibrils use the energy to make the contractions happen.
Cardiac Muscle Cells, Cardiac Muscle Tissue, Cardiac Muscles
Cardiac Muscles- Cardiac muscle is made up of a lot of cardiac muscle tissue. They are found in and and around the heart. These muscles are some of the most highly specialized due to the fact that they have to be constantly working for a persons whole life time. some of these muscles don't even need messages from the brain to do their function they just automatically do it.
