Which tissue type contracts to produce movement?

Explanation:
Movement is produced when muscle tissue contracts. Muscle fibers shorten as actin and myosin filaments slide past each other, driven by calcium signals and ATP. This contraction pulls on tendons attached to bones (in the case of skeletal muscles), creating motion. There are three muscle types—skeletal, cardiac, and smooth—but their common feature is the ability to contract to generate force. Nervous tissue, epithelium, and connective tissue each serve other roles: nervous tissue transmits signals, epithelium lines and protects surfaces, and connective tissue supports and connects structures without actively shortening to move parts.
