myoblast

plural myoblasts

1. An undifferentiated stem cell that develops into muscle tissue.

   It is the deeper parts of such cells which give rise to delicate muscular fibres or networks of fibres, while the superficially placed body of the cell (myoblast), the part which produces the above, performs other functions, and usually bears a cilium.
