Muscle Tissue

• What is caused by contractile proteins located within the muscle cells (muscle fibers)?

  muscle contraction
• What are the three types of muscle tissue?

  skeletal, cardiac, and smooth
• What is being described?

  • Voluntary 
  • Striated (muscle fibers appear banded) and multinucleated

  skeletal muscle tissue
• What is being described?

  • Involuntary
  • Cylindrical and striated but uninucleated
  • Muscle cells are short and branching 
  • Connected to one another by intercalated disks, containing gap junctions

  cardiac muscle tissue
• What is being described?

  • Involuntary
  • Not striated and have a single nucleus 
  • Responsible for regulating the size of organs, forces fluids through tubes, and control light entering the eye
