Presentation Transcript


  1. Cardiac & Smooth Muscle By: Daniel Dierfeldt Molecular Biology

  2. Cardiac Muscle • Involuntary and striated muscle • Cardiocyte = Muscle Cell of the Heart • Short, thick, branched cells • Each cell has only 1 nucleus

  3. Cardiac Muscle • ~10-20μm in diameter • ~50-100μm in length • Each Cell joined by Intercalated Disks. • No Neuromuscular Junctions

  4. Cardiac Muscle • Contain Large Mitochondria • Proteins of Cardiac Muscle are similar to Skeletal Muscle • Mechanism of Contraction similar to Skeletal Muscle • Fatigue Resistant

  5. Smooth Muscle • Long, spindle-shaped cells • No Striations or Sarcomeres • No Neuromuscular Junctions • No Motor Nerves

  6. Smooth Muscle • No Troponin Complex • Calmodulin shuttles Calcium into the Cell. • Mechanism of Contraction differs from Skeletal and Cardiac Muscle. • Interaction of Myosin with Actin same as in Skeletal and Cardiac Muscle.

  7. Smooth Muscle • Encircle blood vessels and other hollow tubes of the body. • Also found lining the stomach, bladder, and uterus.
