Questions and Answers

Which type of muscle tissue is responsible for voluntarily moving the bones in the body?

  • Cardiac muscle
  • Smooth muscle
  • Skeletal muscle (correct)
  • Visceral muscle

Which characteristic is unique to cardiac muscle tissue?

  • Its primary function involves involuntary movements.
  • It is striated in appearance under a microscope.
  • It is attached to bones via tendons.
  • It has the ability to contract without fatigue. (correct)

Where is smooth muscle tissue primarily located in the body?

  • Lining the heart chambers
  • Attached to bones for movement
  • Within the walls of internal organs (correct)
  • Surrounding skeletal muscles

Skeletal Muscle

Attached to bones and move bones using tendons. They are striated and voluntary.

Smooth Muscle

Found inside many internal organs and are involuntary.

Cardiac Muscle

Found only in the heart and is involuntary. It never gets tired.

Study Notes

  • There are three types of muscle tissue: skeletal, smooth, and cardiac.

Skeletal Muscle

  • Skeletal muscles are attached to bones and facilitate movement via tendons.
  • Tendons are connective tissues that link muscles to bones.
  • Skeletal muscle is striated, exhibiting a banded appearance.
  • Control of skeletal muscle is voluntary.

Smooth Muscle

  • Smooth muscle is located inside numerous internal organs, such as the stomach.
  • Its actions are involuntary.

Cardiac Muscle

  • Cardiac muscle is exclusively found in the heart.
  • Cardiac muscle contractions are involuntary.
  • Unlike skeletal muscles, cardiac muscle does not fatigue.
