Dystrophin   Dystrophin stabilizes the
             sarcolemma and protects
             muscle fibres from long-term
             contraction-induced damage
             and necrosis.
             Dystrophin serves to link the
             intracellular microfilament
             network of actin to a complex
             series of linking proteins in the
             cell membrane, and hence to
             the extracellular matrix

Smooth muscle tissue
Significance of smooth
   myocytes




Gastro-Intestinal smooth myocytes:

- Contractile type - Tone of gut, gut motility
- pacemaker (Interstitial cells of Cajal) – tone control, generation of electrical
slow waves
Significance of smooth
  myocytes




Vascular smooth myocytes:
-Tcontractile type - tone of vessel – resistence – blood pressure
- secretory rype – matrix production
