09 Skeletal Muscles
- smooth muscle no striation
- triad of T tubule + 2 terminal cisterna
- A not change
- H and I shrink
- thin filament regulate: regulated by tropomyosin, part of actin
- smooth muscle thick filament regulated
- EC coupling: voltage and depolarization of muscle cell coupled by Ca to contraction of muscle
- contraction of muscle cells follows AP
- CCB main effect on smooth muscle not skeletal
- must get Ca back in for more contraction
