23. 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
30. 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
31. Significance of smooth
myocytes
Vascular smooth myocytes:
-Tcontractile type - tone of vessel – resistence – blood pressure
- secretory rype – matrix production
