- muscle cell
- A connective tissue cell with the ability to convert chemical energy into mechanical energy via a contractile apparatus. As part of the contractile apparatus, the proteins actin and myosin form parallel myofilaments. The interaction of actin and myosin mediates muscle cell contraction in response to stimulation of the excitable cell membrane.

- Mature contractile cells, commonly known as myocytes, that form one of three kinds of muscle. The three types of muscle cells are skeletal, cardiac, and smooth. They are derived from embryonic (precursor) muscle cells called myoblasts.
