The muscles in your arm are primarily composed of what cell type?

The muscles in your arm are primarily composed of muscle cells, known as myocytes. These cells are specialized for contraction and come in three types: skeletal, cardiac, and smooth. Skeletal muscle myocytes are the ones that allow voluntary movement and are found in your arms, enabling you to lift, push, and pull with strength and finesse. Beyond just muscle cells, the arm also contains connective tissues, like tendons and ligaments, that work in harmony with myocytes. Tendons connect muscles to bones, allowing the force generated by contractions to produce movement, while ligaments connect bones to other bones and help stabilize joints. Together, they create a robust system for all your arm's actions!
