produce less lactic acid.
Which type of connection would be found on your rectus abdominus
aponeuroses
Arrange the following steps for contraction in the correct sequence.
- The muscle impulse reaches the sarcoplasmic reticulum and calcium is released.
- Thin filaments are pulled over the thick filaments.
- Calcium floods the sarcoplasm and binds to troponin molecules leaving active sites.
- The impulse arrives at the synapse and travels through the transverse tubules.
- The muscle fiber shortens and contracts.
- Tropomyosin molecules bind to exposed active sites, linking actin and myosin
