Myocyte

A myocyte (also known as a muscle cell) is the type of cell found in muscles. They arise from myoblasts.

Each myocyte contains myofibrils, which are long chains of sarcomeres, the contractile units of the cell.

There are various specialized forms of myocytes: cardiac, skeletal, and smooth muscle cells, with various properties.

Cardiac myocytes are responsible for generating the electrical impulses that control the heart rate, among other things. (See Sinoatrial node)

Kindlin-2 plays a role in elongation.

GATA4 and GATA6 play a role in differentiation.
