Answer 2

Smooth muscles are found along the walls of hollow internal organs such as the esophagus. They are not voluntarily controlled or striated like the skeletal muscles. Their cells have centrally located nuclei and these muscles are small and tapered. They transport substances such as blood and food along organs in the body.
Striated muscle tissue is a muscle tissue that features repeating functional units called sarcomeres, in contrast with smooth muscle tissue which does not.
