Final answer:
All muscle types have common features such as specialized cells, contractile proteins, and calcium ion release. They differ in structure, location, and control.
Step-by-step explanation:
All muscle types have certain features in common. Firstly, they are all made up of specialized cells called muscle fibers that are capable of contraction and relaxation. Secondly, they all contain the proteins actin and myosin, which interact to generate force and movement. Finally, they all rely on the release of calcium ions to initiate muscle contraction.
What distinguishes between the different muscle types are their structure, location, and control. Skeletal muscle is attached to bones and is responsible for voluntary movements, such as walking and lifting weights.
Cardiac muscle forms the walls of the heart and is responsible for involuntary contractions that pump blood throughout the body. Smooth muscle is found in the walls of internal organs, such as the digestive tract, and is also involuntarily controlled.
