Final answer:

The human body has three types of muscle tissues: skeletal, cardiac, and smooth. These differ in structure, control, nuclei count, striation, and location. Skeleton and cardiac muscles are striated and multi or binucleated, while smooth muscle is non-striated and uninucleated.

Step-by-step explanation:

The body contains three unique types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle. Below is a chart that outlines the similarities and differences among these muscle types.

Similarities

  • All three types are composed of muscle cells containing the proteins actin and myosin.
  • Each type is essential for bodily functions and motion.
  • All muscles begin the contracting process when actin is pulled by myosin.

Differences

Skeletal muscle:

  • Striated appearance under the microscope due to the regular arrangement of actin and myosin.
  • Voluntarily controlled by the nervous system.
  • Composed of multinucleated fibers.
  • Attaches to bones and facilitates movement of the skeleton.

Cardiac muscle:

  • Striated appearance but cells are branched and interconnected, allowing the heart to contract as a unit.
  • Involuntarily controlled.
  • Contains one to two nuclei per cell.
  • Exclusive to the heart, enabling it to pump blood.

Smooth muscle:

  • Non-striated due to the irregular arrangement of actin and myosin.
  • Involuntarily controlled.
  • Single nucleus per cell.
  • Found in internal organs and responsible for regulating the flow of substances within various systems of the body.
