Ca in sliding filament mechanism
initiates actin-myosin x-bridge
ATP in sliding filament mechanism
releases actin-myosin x-bridge
Sarcoplasmic reticulum
storage & release of Ca. Also, re uptakes Ca to terminate contraction (muscular version of RER)
T tubule (transverse tubule)
extension of plasma membrane transversely that helps spread the AP between fibers
Differences Smooth Muscle
No striations (sarcomeres). Have lots of thin filaments but little thick filaments
No troponin, rather actin-myosin interaction regulate by myosin conform.(enzyme) & thick-filament assembly
No T-tubules, but adjacent cells have gap junctions = slow wave contractions
Difference Cardiac Muscle
Everything is the same (fibrils, organization)
Different is E-C coupling @ organelle/molecule level
Dematomyositis (skin-muscle inflammation)
Clinical presentation: adult/↓children, characteristic skin lesion (heliotrope rash = eyelids/face)
Histology: interfascicular inflammation, perifascicular atrophy (atrophy only near skin/periphery) = pathognomic
Polymyositis (muscle inflammation)
Clinical presentation: adult women, onset week-month, Proximal weakness, ↑ CK, responds to corticosteroids
Histology: necrosis, regeneration (enlarged nuclei), inflammation (lymphocytes)
Denervation Atrophy
angular atrophy
fiber type grouping
Define congenital myopathy & causes (3)
present birth floppy baby, slowly progressive, genetic errors in metabolism machinary
-defect storage/synthesis glycogen
- defect carnitine palmiiotoyltransferase
-defect respiratory chain
Skeletal Muscle Cell K/Na concentrations
K+ high inside cell (2) &Na+ low inside cell (3) = (Na/K ATPase) & cell becomes more negative inside

Skeletal cell HIGH Cl- permeability results in only more Em negative by 3mV.
Skeletal cell HIGH Cl- permeability results in:.
- Decreases spontaneous excitability (requires large stimulus) & slave to NS
- Relieves need for K efflux (repolarization) thus uses less ATP in ATPase pump
