What is a myocyte?

• A. A type of nerve cell
• B. A blood cell
• C. A connective tissue cell
• D. An individual muscle cell

Answer: (D)

Muscle cells specialize in contraction, powering movement and force generation. A myocyte is simply a muscle cell—the basic unit of muscle tissue. These cells, whether skeletal, cardiac, or smooth, are designed to shorten and generate force. The prefix “myo-” means muscle and “-cyte” means cell, so a myocyte is an individual muscle cell. This is different from nerve cells (neurons) that transmit signals, blood cells that circulate in the blood, or connective tissue cells like fibroblasts that build and support the extracellular matrix.
