type of muscle tisue

• Skeletal muscle:

  • Most muscle is skeletal
  • skeletal muscle is attached to the skeleton
  • Skeletal muscle is responsible for causing movement of the skeleton
  • Skeletal muscle is made of cylindrical cells that join to form multinucleated myofibrils
  • skeletal muscle has a striated pattern when stained and viewed using a microscope
• Cardiac muscle:

  • The heart contains cardiac muscle, it is used to pump blood.
  • Cardiac muscle is myogenic, meaning that it doesn't require input from the nervous system to contract and relax
  • Cardiac muscle cells are branched to allow contraction across the whole ventricle or atrium.
  • Cells are uninucleated
  • Cardiac muscle is striated when stained and viewed under a microscope
• Smooth (involuntary) muscle:

  • Smooth muscle lines organs, arteries, and arterioles.
  • By contracting and relaxing, it causes movement of the contents of an organ or blood vessel
  • smooth muscle cells are uninucleated
  • Smooth muscle tissue is spindle shaped
  • Smooth muscle is not striated.
