Explain how muscles change their shape ?

Text Solution

Verified by Experts

The shape of muscles depends on ability to adapt to external forces. When placed under high demand, they generate great strength and power and maintain durability. Muscle is a soft tissue and their cells contain protein, filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and shape of the cell.
