| If cross sections of the myofibril at different levels of the sarcomere are examined by electron microscope, the filaments can be seen end-on, and the three-dimensional nature of the lattice of filaments can be appreciated. |
| The difference in the spacings in the top epicardium layer and the rest of the heart may indicate that sarcomere lengths in those regions are different. |
| The cardiac sarcomere is the contractile unit in each cardiac cell. |
| It turns out that C protein sensitizes certain parts of the sarcomere to calcium. |
| Effect of postrigor sarcomere length on mechanical and structural characteristics of raw and heat-denatured single pork muscle fibres. |
| Combined with the use of a single ATP, the interaction of myosin and actin creates movement and shortens the sarcomere. |
