There are five characteristics of Muscles; namely Responsiveness, Conductivity, Contractibility, Extensibility and elasticity. Assigning each example to the universal muscle characteristic being described; Conductivity; (electrically stimulating a muscle) Local electrical change triggers a wave of excitation that travels along the muscle fiber. Contractibility; Shortens when stimulated Elasticity; Returns to its original resting length after being stretched, Extensibility; capable of being stretched between contractions. Responsiveness; to chemical signals, stretch, and electrical changes across the plasma membrane.
