- Muscle cells, also known as myocytes, are specialized cells designed for contraction and force production. Skeletal Muscle Cells: These cells are long, cylindrical, and have a striated (or striped) ...

When a muscle contracts, the parts of a sarcomere "shorten" and come closer together. Each cardiac muscle cell can have over 5,000 sarcomeres, which compounds both the shortening and relaxation events ...

Now, in a study in zebrafish and human heart muscle cells, researchers show that a tiny deletion in the A-band of titin — the loss of just nine amino acids out of more than 27,000 to 35,000 amino ...
